A keypad door lock is a great way to add an extra layer of security to your home. In this blog post, we’ll show you how to install a keypad door lock in just a few simple steps.


Installing a keypad door lock is a great way to boost your home security. Before you begin the process, there are some preparations you should take. This includes checking to make sure you have all the necessary tools, measuring the space where the keypad will go, and ensuring that you have access to a power source for the lock. All of these preparations are important for a successful installation.

Gather the necessary tools

Gathering the necessary tools is an important step in successfully installing a keypad door lock. Depending on the type of door lock you are installing, you may need a keyhole saw, drill driver/bits, level or other standard hardware or carpentry tools. Having all the right instruments ready before you begin will make installation faster and smoother. It is important to use the right tools to ensure that the door lock is installed properly and securely.

If you do not have access to specialized tools or feel uncomfortable using them you can always contact a professional locksmith to take care of your installation needs.

Measure the door and the hole for the lock

The first step in installing a keypad door lock is to measure the door and the hole for the lock. This will ensure that you purchase a durable and reliable lock that will fit your door frame. If you have existing holes, it’s important to note if they line up with the holes specified by the manufacturer of your chosen lock. Once you have taken accurate measurements, consult the user manual to ensure that your chosen model is compatible with the dimensions of your door. If necessary, adjust pre-existing holes to meet those specifications before proceeding with installation.

Removing the Old Lock

Before you can install your new keypad door lock, you must first remove the old one. Depending on the age and type of lock, this process may vary. Regardless, this step is essential in order to make room for the new lock, and ensure a secure installation. Let’s look at the process of removing the old lock.

Unscrew the existing lock

Before you can install a new keypad lock on your door, you will need to remove the old one. Unscrewing and removing the existing lock is necessary in order to make sure that the new lock system fits properly and securely in place. Before beginning, turn off any power sources supplying power to your door lock, such as electricity or batteries.

Unscrew the bolts that fasten the door’s strike plate to the door jam. Then remove the key cylinder from its faceplate by unscrewing it from beneath or behind. On a mortised model, use a screwdriver to press down on the metal spring clips and slide out the complete lock assembly from its casing in the edge of the door.

Next, unscrew or pull out any screws holding back plate of this lockset’s strike plate onto its jamb bracket and pull off both pieces of hardware from doorway. Finally, use a screwdriver or drill bit to unscrew any remaining mounting hardware around edge of old lockset before disposing of it properly, including any electronics and all mounting hardware associated with it.

Disconnect the wires

To begin, disconnect the wires going to your old lock. You should see two or three colored wires coming from the back side of the cylinder, these colors represent different functions: a card reader, an unlock function and an alarm. Carefully unscrew and remove each wire to avoid damaging them. If your lock includes a key pad, you may need additional specialty tools in order to safely disconnect it. Be sure to store all of your old parts in a secure location for potential future use. Once all of the necessary cables are disconnected, you can then move on to installing your new keypad lock.

Installing the New Lock

Installing a keypad door lock can be a great way to increase security at your home or business. You will need to follow detailed instructions to ensure the lock is properly installed. In this section, we will discuss the steps you will need to take to install the new keypad door lock.

Insert the new lock into the hole

Beforeyou insert the new lock into the hole, you need to check that all the components are in order. This includes the mounting plate, wrench, door latch, and keypad. Make sure that all of these items are snugly held together by the components screws and nuts. When everything is secure, align the mounting plate with the edges of your door frame so that it fits evenly inside.
Once you have properly secured the mounting plate to your door frame and aligned the parts, take a Phillips screwdriver to attach them together. Use screws from outside-to-inside inside-to-outside sequence to ensure a snug fit. If your lock has a number code on it for protection against brute force attempts from thieves or intruders, make sure this code is correctly set as well before replacing any screws or bolts.
Once everything is tightened and secure, insert your new lock into its housing provided by the mounting plate. Firmly press down until it clicks into place and adjust as necessary until it’s completely flush with your door frame or wall surface. Test it out by locking and unlocking several times – this will ensure that all components are securely locked into place before moving onto the next steps of installation!

Secure the lock with screws

Once your keypad lock is placed in the door, you’ll need to secure it with screws. This will help to ensure the lock is securely fastened in place and won’t become loose. Be sure to check that the screws are tightened. Test that the lock works by entering a combination before you fully tighten them.

There should be two screws included with your lock, as well as two holes in the back of the casing for installing them. Secure one screw at a time and keep an eye on any movement of the main plate itself- some locks may require slight adjustment when fitting the last screw so that everything lines up perfectly when locked. Use a small Phillips head screwdriver to install these screws and make sure they are tightened properly before finishing installation.

Connect the wires to the new lock

Carefully connect the wires from the inside of the door to the new lock’s terminals. Ensure that you have matched each colored wire to its appropriate terminal in order to ensure successful installation. Make sure you make all connections firmly as a loose connection could be hazardous and lead to an incomplete or inaccurate wiring system. You should ensure the wires are not pinched and are safely tucked away from exposure and movement which could damage them.

If your new keypad lock comes with a battery backup, be sure to install this as well, connecting both of its wires properly for power supply. As next step, a proper grounding system must be connected if you want optimal security and functionality. This often consists of connecting a ground wire (green-colored) to either the door frame or via an additional ground plate that comes with your keypad lock product.

Programming the Lock

Programming your new keypad door lock is the last step in the installation process, and also one of the most important steps. It is essential that this step is completed correctly so that the lock functions as expected. This article will provide you with a step by step guide on how to program the lock. We’ll cover the different programming options available, and how to set a code for the lock.

Enter the factory-set code

Once the wiring is complete and the battery installed in your keypad door lock, you are ready to set your personal entry code. To enter the lock’s factory-set code, press and hold the “program” button until the keypad beeps. At this point, you will enter a 6-digit code. This can be any number from 0-9; most people select a combination of meaningful numbers or birthdays – something that is easily remembered.

Next, make sure to confirm this code by pressing “#” and then entering it again. Finally, press “#” once more to save your custom code. After that, you’ll have to turn your deadbolt on manually by using the single cylinder knob that came with your lock kit. Once in position, you can use your new keypad door lock as normal – simply press # or 0 (depending on model) followed by your custom 6-digit code to open and close it at will!

Create a new code

Creating a new code for your keypad door lock is a simple process. Before beginning, make sure that the set screws on the inside of the keypad are loose, allowing you to open the unit. The following steps will help you create and program a new code for your keypad door lock.

1. Locate the programming button on the inside of your keypad – it may be labeled ‘reset’, ‘prog’ or something similar. Press and hold this button until you hear two beeps from the unit; your current code is now cleared out and you can enter a new one.
2. Choose a four to eight digit code that is easy to remember, but difficult to guess by an intruder or anyone else who doesn’t have permission to enter your premises. Avoid using commonly used patterns such as 0000 or 1234 when selecting your access code as they can easily be guessed by any would-be intruder wanting to gain entry into your property without permission.
3. Enter your chosen access code via the keypad – each press of a digit should result in one audible beep from the unit confirming entry into its memory bank – then press enter or ‘*’ to finish programming process. You will now hear two consecutive beeps from the unit confirming successful entry of new access code
4. Tighten up set screws on interior side of keypad so all parts remain secure whilst programming process runs its course
5. Test out newly programmed access code and make sure it unlocks door easily before setting back away from entrance/exit point

Test the new code by locking and unlocking the door

Once you have programmed your new code into the keypad lock, it is important to test that it is functioning correctly. To do this, first ensure any existing codes are deleted (refer to manual). When the code has been completely deleted, you can proceed to testing whether the newly set code allows access. To test your new code:

1. Enter your chosen code into the keypad.
2. Lock and unlock the door in quick succession using the lock button or turning the deadbolt lever depending on your type of lock system (refer to manual for specific instructions).
3. Test that both functions are working correctly and achieve a secure locking position when required. If not, repeat steps 1 to 3 until both functions are working properly.
4. Check that incorrect codes are not accepted by attempting entry with alternative numbers and verify that entry is denied as expected.
5. Once you have run all tests successfully, you can be sure of a safe and secure lock mechanism with only access granted upon input of your chosen code!

Finishing Up

Installing a keypad door lock is a great way to add an extra layer of security to your home. You’ve finalized the installation process by bolting the keypad door lock in place and testing out the code you’ve set up. Now it’s time to put any final touches in place. This section will cover how to tidy up the area around the door and how to replace the batteries in the keypad door lock.

Replace the cover plate

The next step is to replace the cover plate on the door jamb. Slide your hand back inside the space where you previously installed the door bolts. If everything looks good, carefully place the cover plate on the jamb like a puzzle piece until it fits into place. Make sure you push it all the way into the jamb before attempting to attach the mounting screws. At this point, it should be fairly easy to see all of your pre-drilled mounting holes and you’re ready to attach your screws with either a Phillips head or flathead screwdriver.

Once you have secured this piece in place with several lengthwise mounted screws, you’re finished with installation! It’s time to check out how conveniently your keypad lock works for you and enjoy its security benefits every day. Be sure not to lose any of your keys as backups!

Test the lock one more time

Before you finish the installation, test the lock one more time. This is your last chance to ensure that everything is working correctly. Enter the master code again, and then use the user codes to unlock and lock the door. Make sure that both work properly, and that different user codes all produce different results when used at the keypad. If this all works, you can be assured that your keypad door lock has been installed successfully!

Clean up the area

Once you have passed all the steps, it is important to properly clean up the area around your newly installed door lock. Make sure to pick up and discard any scraps of wood, plastic or metal that may be left from the installation. Use a damp cloth and mild cleaning solution to wipe off any dirt or dust that has accumulated on nearby walls as this can increase the risk of a potential fire hazard. After lightly moistening and wiping down the surfaces around your new lock, ensure that all power tools are unplugged and stored away in an orderly fashion. Finally, make sure to properly store any excess door lock wiring out of reach from children or pets. A tidy workspace will significantly reduce potential future accidents and provide you with peace of mind knowing that your new keypad deadbolt is safe and secure for daily use.
