How hard is it to install a keyless entry system: How to Install a Keyless Door Lock

How to Install a Keyless Door Lock

Keys are so 20th century. These days, the way to go is keyless. That’s because keyless door locks offer a degree of convenience that keyed locks never could. You never have to worry about losing your keys, because as long as you can commit a few numbers to your memory (or if you have your trusty fingerprint with you), you’ll always be able to enter your home. Plus, if you go out for the night and aren’t driving, you won’t have to worry about carrying a bulky keyring with you, because — that’s right — keyless!

Here’s everything you need to know about keyless door locks and how to add them to your home.

Keyless Door Lock Styles

There are two basic kinds of keyless locks: mechanical and electronic. Mechanical locks usually consist of a series of metal buttons that you push in a certain order to unlock the door. The order corresponds to a code, so if you pushed the first, third, second and fifth buttons, your code would be 1325.

Electronic locks also work via a code (and sometimes a fingerprint), but they need a battery to operate. Among electronic locks, there’s a range of options, including locks that do little more than open after your code is entered and those that connect to your home’s Wi-Fi system and allow you to operate the door when you aren’t even home. The most advanced version of these locks also can offer you the chance to send digital «keys» to visitors. You can set the key codes to work for a specific period of time, after which they will cease to function, so these kinds of locks are perfect for people with short-term rental units.

Installing Keyless Door Locks

Most keyless door locks are deadbolt-style, although there are some that operate as a door handle — albeit with mixed reviews regarding reliability. If you decide to go with a doorknob-style lock, you will simply remove the old doorknob and slide the new one into place, following the directions included with the device.

The much more common deadbolt version of keyless door locks can also be installed just as simply. If you have an existing deadbolt, installing the new lock can be as simple as removing it and sliding the new one into place.

If you don’t yet have a deadbolt on your door, then the project gets significantly more complicated. You’ll need to drill a hole for the lock on the door, a slot for the bolt to slide through and chisel out the area for the strike plate on the door jamb. If you’re starting from scratch, check out our instructions on how to install a deadbolt. Instead of inserting a standard deadbolt, you can simply install your keyless lock.


Particularities of Keyless Door Locks

While keyless locks install the same as traditional locks, there are a few things to be aware of during installation:


Keyless door locks tend to be larger both in height and thickness than standard deadbolts, so be sure to check the dimensions of the new lock and make sure it will clear your door handle. You want to make sure it won’t be so thick that it bumps up against your storm door.

Electronic Components

Whereas in a standard deadbolt installation you simply need to align the two sides of the lock and screw the assembly together, electronic door locks are going to involve batteries and some kind of electronic link between the two halves. The instructions that come along with your lock will walk you through the exact details, but the installation usually involves feeding through a small cable from one side to the other that plugs into a port to provide power to the lock mechanism.

Strike Plates

In most installations, you’ll be able to keep your existing strike plates in place and simply slide the new lock into place. If, however, you find that the bolt isn’t sliding smoothly, you’ll need to replace these with the versions that come with your lock. This is actually something you might want to do anyway so that the hardware all matches. If you still find that the bolt isn’t working properly, you might also need to chisel out more of the wood in the jam where the bolt inserts to ensure it has proper clearance.

Setting the Code

Finally, keyless door locks always need to have their code adjusted after they are installed – whether they are mechanical or electronic. For mechanical locks, this often involves turning a screw a quarter turn, flipping a latch to clear the old code, and entering a new code. For electronic locks, you are usually provided a master code which, after being entered, will put you into programming mode from where you can enter your new combination.

One significant difference between the two styles of locks is that electronic deadbolts will allow you to enter multiple combinations, while mechanical styles usually only allow one combination at a time. In either case, it’s critical that you save the master codes and the procedure to change the codes in a secure place because those instructions will be critical if you need to change the code or if you’ve forgotten the one you’ve programmed.

One-Sided Installation

The vast majority of keyless door locks replace existing deadbolts or get installed as new deadbolts. This means you’ll have both a new outside lock face — the part that’ll have the combination pad — and a new inside lock face, which usually has a simple thumb-turn lever.

Should you decide you want to forgo the keypad/code situation but still access your home without a key, there are several companies that offer options that mount right over your existing deadbolt interior hardware, such as the August Smart Lock and the Kwikset Kevo Convert.

To install these locks, you simply tape the outside portion of your deadbolt to the door (the key side), then remove the inside portion, where the thumb-turn lever is. After installing a mounting bracket, you slide the new mechanism on top of the lock stem, and then you can open and close your door using an app on your phone. You can also program your lock to open automatically when it senses authorized smartphones in the near vicinity. And because you’ll only be replacing the inside portion of your lock, you’ll still be able to open the door with your existing deadbolt key.

How to Install Keyless Door Lock? Step by Step Instructions

Keyless Intelligent door locks provide convenience and security to your home by eliminating the need for keys. Keyless locks are easy to install and don’t require expensive equipment; you don’t have to be an expert handyman or pay exorbitant installation fees.

However, you must ensure you have all the necessary parts before starting your installation.

How to install a keyless door lock step by step?

Now, let’s get to the step-by-step instructions on installing a keyless door lock.

What tools will you need to install a keyless door lock?

As you prepare to install your keyless door lock, you must know what tools you need. This can vary depending on the brand and model of the keyless door lock you purchased. However, there are some standard tools used for most installations:

  • A screwdriver. It is best to use an adjustable head, as this will allow different size screws.
  • Drill bits. This tool is used to drill holes into walls or doors so that screws can be put through these holes so that nothing slips out of place during installation. You will want to make sure the bit is a perfect fit for the size of your deadbolt; if it doesn’t fit correctly, it could cause damage to your lock or door frame when installed.
  • Socket wrench or ratchet wrench– This tool is used for removing and installing hardware like hinges and handles from doors or drawers (as well as many other things).
  • Tape measure- Use this tool and measuring marks on doors/windows, which should help guide where measurements should go during installation.
  • Batteries – These are needed for the keyless door lock to work properly. If there aren’t any batteries included with your purchase, ensure there is a battery compartment before installing anything else, or else the device won’t function properly after installation.
  • Chisel and hammer. To cut the mortise in the door, use the chisel to shave off excess wood around the edges of each side of the lock. Then use your mallet to tap on it until you have a nice, clean-cut hole for your lock’s mortise.
Step 1: Prepare all necessary tools.

Before installing your new keyless door lock, ensure you have all the necessary tools. You’ll need a few screwdrivers, a drill or screwdriver bit set, a level, and at least one drill bit.

Step 2: Remove the Old Door Lock

The first thing you should do is remove any old hardware on your door. This includes any handles or knobs attached to it.

Start by removing your old door lock (if you don’t already have one). If you’re replacing an existing lock, remove the screws holding it in place with a screwdriver.

If this is a new installation, you’ll need to remove any screws attaching the current hardware to your door before removing that hardware.

Note: please clean up all surfaces. Clean off any dust or debris you may have created by removing your old lock by wiping down all surfaces with a damp cloth or paper towel, making sure to wipe both sides of the door frame and the inside and outside surfaces of the new door lock once installed.

This will prevent dirt buildup inside your new smart door lock mechanism that could cause malfunctions or damage to parts over time due to a lack of lock maintenance on your part!

Step 3: Fit New Keyless Door Deadbolt

Next is preparing your new keyless deadbolt by removing its packaging and mounting plate and setting them aside. Make sure you know where these pieces go later on before continuing!

Next, we want to take our deadbolt unit (the part with two side holes) and line up our strike plate to see how much room we have left when connecting them later during installation.

Fit the new keyless door lock into the door, and mark where you need to cut it so it fits snugly in place.

Step 4: Install the strike plate.

Remove the old latch and strike the plate. If they are screwed on, use a screwdriver to remove them. If they are held in place by clips, press down on the top of each pin with your thumb while pulling outwards until it releases.

Step 5: Mount the faceplate and secure it with screws.

Fit a new latch onto the door and then fit a strike plate over it until it clicks. Mount the faceplate and secure it with screws. If you’re replacing an existing faceplate, unscrew it from its current position.

If possible, use screws rather than glue when mounting them together—this will allow easy removal if necessary!

Step 6: Adjust if needed.

Adjust if needed by loosening or tightening any screws until everything is aligned correctly; test by locking/unlocking several times with keys and codes if unsure whether adjustments have been made accurately.

If you want to adjust keypad sensitivity (to avoid false entry), remove the battery cover from the back side of the casing and carefully bend tabs away from the inside surface of the case until the desired level of sensitivity is reached (be careful not to break off tabs).

Step 7: Test the lock

Open and close your door five times a row, making sure that all locks work as they should by locking and unlocking them each time you close your door. There will be some resistance when turning the keyless deadbolt, which is normal and helps keep intruders out of your home.

Step 8: Program Your New Lock and set a new code.

The last step in installing a keyless entry system is programming it so only you can get inside! You must set a programming code to manage this Keyless Door Lock. Also, you need to set a new guest code for your daily use. can’t be loaded because JavaScript is disabled: Keyless Door Lock Install & Top 5 Questions | Schlage Connect (https://www.

Door locks, even on expensive cars, sometimes stick, especially in the cold. Installing keyless entry on the car significantly reduces the time to open the doors and start the engine. To get into the salon, you don’t even need to get the keys. To open the doors, it is enough to find the key fob in your pocket.

What does keyless entry mean in a car?

Installation and connection of keyless entry guarantees comfortable opening and closing of a car without using keys. Electronic equipment exchanges coded information between the driver’s key fob and the unit installed inside the car. Thanks to this, the system provides identification of the owner and unlocks the locks when he approaches the car.

How keyless entry works

There are many keyless entry systems with different functions and options. Among them there are both standard (installed at the factory) and manufactured by third-party manufacturers. The latter are highly versatile. Car owners can install them on a car with their own hands or in a service station.

In general, the keyless entry system works as follows.

  1. After the engine is turned off, the microcircuit inside the key fob performs radio exchange with the control unit. When the driver leaves the passenger compartment and removes him for a certain distance, the locks are activated.
  2. When the owner approaches the car, the exchange between the key fob and the control unit is resumed. The ECU transmits a signal at a frequency of 125 kHz. The key fob chip responds to 433 or 866 MHz. A number of models provide for the need to send the first request from the driver. In this case, he must press the corresponding button on the key when approaching the car.
  3. Depending on the algorithm used, the locks open either automatically when the driver approaches or by hand pressing the door handle.
  4. To speed up the start of the engine, a start-stop button is used, which also exchanges coded information with the key fob chip.

The system installed in the car can perform a number of additional functions such as opening the trunk, operating power windows, etc.

To increase security, each kit uses its own unique exchange algorithm. The control unit transmits an encoded sequence, to which the built-in key must respond with a strictly defined digital message. With each new call, the transmitted request and the response combination change in a quasi-random manner.

Additional protection is provided by a very high rate of radio exchange between the elements of the system. The protocol provides for receiving response signals within nanoseconds. These factors make it impossible to decrypt and crack passwords in real time.

How to make keyless entry in a car

To install keyless entry in a car, you can purchase ready-made kits or assemble the circuit yourself from individual elements. In the second case, some savings are possible. However, it is much more convenient and reliable to use fully equipped and ready-to-install systems.

In general, the following components are required.

  • Transponder. A transceiver device implemented on an electronic board.
  • Antenna. Provides direct connection of the unit installed in the car with the driver’s smart key. There are options with several antennas on the car.
  • Touch sensors. Additional functionality that is not always used. The installation of such sensors ensures that the car access system is triggered when the hand touches the door.
  • Start-stop button. Used to start and stop the engine, as well as turn on the ignition mode.
  • Central locking. It is not always used, it can be used already installed on the car.
  • Control unit. Provides coordination of the work of all components and the system as a whole.
  • Connecting wires.

Only experienced drivers who are well versed in electronics will be able to independently assemble and install such a circuit with their own hands. To avoid unnecessary risk and save time, it is more advisable to purchase a ready-made kit with optimal functionality for yourself. Various devices provide options for remote autostart and trunk opening, the presence of an immobilizer, etc.

Installing keyless entry in a car generally involves the following operations. The specific algorithm may differ depending on the vehicle model and system configuration used.

  1. Installation of the control unit. It is advisable to remove it under the torpedo.
  2. Installation of start-stop button.
  3. Car cabling. If necessary, installation of additional sensors and antennas, connection of electric drives for opening doors, power windows, trunk, etc.
  4. Connection to on-board power, alarm, central locking.
  5. Setting and synchronization of work.

How to set up the keyless entry

After installing all the components on the car, it is necessary to set up the hardware. The algorithm of actions differs depending on the device used. In the general case, it is necessary to coordinate the operation of the electronics with the alarm, the engine control unit and the central lock. Synchronization with a smart key is also performed. The actions required for this are described in the instructions for a specific kit.

Activation of keyless entry

After setting up and synchronizing the system, it is necessary to activate it. Some models are activated automatically upon completion of the setup. Others require additional steps. After a single activation, keyless entry will work until it is forcibly disabled.

Keyless Entry Wiring Diagram

When keyless entry is installed in a car, the specific wiring diagram depends on the system used and the car model. In general, it is necessary to connect the control unit to the power supply, signaling, central locking, antennas, sensors and actuators. It is also required to connect and properly power the start-stop button.

The spatial distribution of individual elements is shown in fig. 5, a variant of the connection diagram — in fig. 6 (car Lada Priora).

How to use keyless entry in your car

Installing a keyless entry system in your car makes it much easier to open and close your car, as well as start and stop the engine. The following details how to open the car and start the engine. There is also the possibility of closing the car with the engine on and completely turning off the function.

After the start of the movement, the door locks are automatically locked and the start-stop button is blocked. This provides security and protects against accidental launch activation. After stopping, pressing the start-stop button turns off the engine and opens the door locks.

How to lock a running car with keyless entry

A number of devices allow you to lock a running car without stopping the engine. This is especially convenient in winter. To perform the operation, you need to get out of the car without turning off the engine. After that, use the key fob to remotely close the locks.

Another option is to automatically lock the doors after getting out of the car. Some devices require this function to be activated inside the car beforehand.

How to open a car with a keyless entry

When the driver approaches the locked car, a radio connection is established between the smart key and the indoor unit. Depending on the algorithm used, various options for the owner’s actions are possible.

  • A number of systems provide automatic door unlocking. The driver does not need to perform any action, it is enough to come close to the car.
  • The owner needs to bring his hand to the door or press the handle (button). The blocking is removed after the sensor is triggered.
  • When approaching the vehicle, the owner must press the key button to establish a connection between the system components. Subsequent unlocking is carried out similarly to one of the two options described above.

How to start the car with keyless entry

To start the car, you need to get inside the passenger compartment with a smart key and press the start-stop button. Depending on the model, you must first depress the brake or clutch pedal. In some cases, you will also need to hold the key fob next to the hidden immobilizer or insert the key into the ignition socket.

There is also remote start and auto start functionality. For example, you can start the engine remotely by pressing the corresponding key button three times.

How to disable the keyless entry

There are different options to disable the circuit after installation, depending on the model. For example, on Lexus vehicles, the following method is used:

  1. The close button is pressed and held.
  2. Without releasing the first button, press «open» twice.

Alternative combinations can be used to disable other devices, usually also quite simple.

Why the key is in the keyfob

There is a chip inside the keyfob that functions as a smart key. It is used to exchange coded information with the vehicle’s control unit. After establishing a connection between the key fob and the ECU, the key is identified. This ensures security by preventing unauthorized unlocking of the locks.

Keyless entry stopped working

Some time after installation on the vehicle, the equipment may start to fail or even fail. Malfunctions are caused by various factors. Among them, it is worth highlighting corrosion, water ingress, mechanical damage, temperature fluctuations, software failures, etc.

The car does not see the keyless entry key

If the car does not respond to the smart key at all, there may be several basic problems.

  • The batteries inside the key fob are dead (or poor contact).
  • Electromagnetic interference or shielding of radiation. Sometimes it is enough just to shift the key to the other hand.
  • Wear, damage to the internal contacts of the remote key.
  • Software failure. Requires a reset or reprogramming of the key fob. The same procedure may be necessary after installing a new battery.
  • Contamination or icing of the car body. This happens more often with older cars.
  • Temperature fluctuations (heat or severe frost).
  • Problems with power supply inside the car (battery dead).

Some vehicles have an automatic lock function after a long period of parking. In this case, you need to open the lock with a mechanical key.

Keyless entry locks but does not unlock car

If the key fob does not unlock the car, the problem may be with the sensors. For example, the system does not open the driver’s door due to a malfunction of the sensor located on it. Such sensors often work only for opening, and do not take part in closing the locks.

A malfunctioning sensor or button can be caused by dampness, icing, dirt, normal wear and tear, or corrosion.

Keyless entry button repair

To troubleshoot buttons or sensors, it may be enough to wash the relevant door or remove dirt (frost) from it. If cleaning the component and washing the car does not help, the part may need to be repaired or replaced.

The keyless access button is frozen

In severe frosts and ice conditions, the button may freeze and not respond to pressing. To fix the problem, it must be warmed up and, if necessary, dried. If the car is outside, you can try to gently heat the button with a lighter or other method.

I washed the engine and the keyless entry stopped working

If the system stopped working after visiting the car wash, the problem is most likely caused by water getting on the sensitive elements (sensors, gauges) or connectors of the connecting cables. To fix the problem, you will need to remove the liquid and dry the damp component.

After washing the engine, problems with the electronics are also possible. To eliminate the failure, it is enough to briefly disconnect the battery terminal.

what it is and development prospects

In recent years, among the options offered on the market, you can find the so-called keyless entry system in the car. It is equipped with a large number of models of various price ranges, including even relatively affordable cars.

However, not everyone knows what such a system is and how it works. It is logical that motorists have many questions, including its reliability, efficiency and, of course, the degree of protection of the car from unauthorized entry by intruders. It is about what a keyless car access system is and what is the principle of its operation that we will talk about in this material.

The history of appearance

The ability to exclude the key from the list of accessories necessary for a car enthusiast has attracted car engineers and ordinary motorists since the middle of the 20th century. Not without reason during the Soviet Union, motorists tried to independently install a button to drive the starter instead of the ignition switch on the products of the domestic automobile industry.

However, such a «modernization» did not allow to do without keys in the literal sense of the word, but only reduced their number. It is known, after all, that on a number of Soviet cars there were two different keys at once — one for the driver’s door and trunk, and the second — directly for the ignition switch.

Video — how keyless entry to a Kia Sorento car works using Autolis Mobile:

As you can see, the principle of operation of the system is very simple, and a reader familiar with the basics of electronics may wonder why such systems appeared only in the 90s of the last century, and not earlier. After all, the properties of radio signals were well known much earlier.

The answer to this question can be the main technical difficulty faced by the developers of such systems — ensuring the safety of the car.

The machine must «learn» only the owner’s key, and at the same time remain inaccessible to access attempts from third parties. The first experiments with radio tags showed that the key signal could easily be intercepted and re-simulated, and therefore a hijacker equipped with a portable radio signal receiver and transmitter could easily take possession of the car. Cryptoprotection looked like a logical way out of the situation, but once the code was received, it still made the car vulnerable.

The solution to this problem was the emergence of digital systems and, as a result, complex coding based on a digital signal. This made it possible to build a system of interaction between the car and the smart key based on a «floating code».

Such interaction implies the presence of a large number of options when, and at the stage of preliminary interaction of the key with the block in the car, an arbitrary code variant is generated from the available ones.

In practice, this means that even if an attacker intercepts the sent code, he will not be able to use it, since other numerical values ​​​​of the electronic encoding will be generated. Since there can be a huge number of code options, the possibility of randomly choosing the desired encoding is reduced to almost zero.

What keyless entry systems are in use today and how do they differ?

Answering this question, it is immediately worth noting that the differences between the systems lie, first of all, in the form, not in the content. The principle of operation of systems for all automakers is similar, and only the form of the smart key differs, as well as the scheme for its use.

So, some systems, especially on cars of the late 90s and early 2000s, still have a folding key that is used «just in case». So initially, automakers tried to protect the owner from a possible malfunction in the keyless entry.

Today, there are practically no such options, and a smart key is either a key fob or a smart card. In the first case, as, for example, on Volkswagen and Audi cars, the key fob simultaneously plays the role of an engine start button.

Once in the car, the owner pushes it into a special groove and thus activates the starter. The smart card system (pioneered by Renault) is somewhat different.

Video — how keyless entry to the car and the start-stop button work:

The card does not need to be inserted anywhere, just that it is in the owner’s pocket or wallet. That is, he approached the car — the doors were unlocked, and you just need to get behind the wheel, press the button and start the engine.

An interesting variation of the smart key is the development of Jaguar, which it has implemented on its latest F-pace crossover model. Here, the role of the identifier is performed by a wrist bracelet, which does not require batteries and is made in a waterproof design.

Undoubtedly, in terms of its convenience, this system of access to a car without a key surpasses all others, because the owner does not risk losing a smart key or card. At the same time, he can safely go to the beach without thinking about where to leave the keys to his car.

Almost certainly other car manufacturers will soon copy this solution, of course, in their own variations. Perhaps the chips will be integrated into watch bracelets or even jewelry, but for now this is a matter of the future.

Prospects for the development of keyless car entry systems

At first glance, it may seem that keyless car entry systems are already perfect at the present stage and do not require any modifications. Indeed, on expensive brands of cars, such complexes can not only open a car without a key and allow it to start, but also restore individual seat settings for a particular driver and even turn on your favorite disc or radio station in the multimedia system.

However, progress is not standing still, and car manufacturers are working closely with electronic component suppliers to look for ways to further develop such systems.

One of the priority areas in this is the integration of the system with mobile communications — primarily with smartphones. Here, however, lies the same problem that was at the dawn of the appearance of keyless systems — the issue of security from outside interference.

Video — «pitfalls» of keyless entry on the example of Skoda Superb:

Experts also predict the emergence of cheap systems with fingerprint sensors that can be integrated into the car handle. Alas, the issue of reliable identification in any conditions, in a wide range of external temperatures and in case of contamination of the car body, is still acute.

Scientists simply cannot create a sensor that would work reliably both at positive and negative temperatures, in rain, snow and slush. For this reason, the use of fingerprint systems is limited only to access to secondary functions of the car — the same settings for seats and electronic devices. In addition, the high cost of such engineering «frills» also affects, not without reason that only Audi decided to use fingerprinting in its flagship A8.

Features and disadvantages of modern systems

Many car owners are wondering how reliable keyless car entry systems are. After all, the fact is known that the more complex the device, the more it is subject to various problems.

In addition, the climatic conditions in our country are far from ideal, and drivers quite logically think about how the system will work in cold weather or, conversely, in hot weather.

The experience of service centers shows that the fears of motorists are, in fact, in vain. Of the total number of breakdowns in modern cars, the keyless entry system presents «surprises» extremely rarely. In terms of protection against theft, it is also very reliable, but when used in conjunction with anti-theft systems. However, the immobilizer function in such devices is available “by default”, and it is sufficient for basic vehicle protection.

However, there may still be problems with the car’s keyless entry system. They are connected, first of all, with inattention. So, if you lose your key fob or card, you will not get access to the car.

Moreover, you can unlock the system or “write” a new key in the memory of the block only at the official dealer center, not a single “garage” service will undertake such a task. In principle, at the time of purchase, a duplicate can be foreseen in advance, but it should be stored very carefully.
