If you have a Vivint door lock, you may need to change the battery at some point. Here’s a quick guide on how to do it.


Repairing your Vivint door lock is a simple task that requires some basic precautions to ensure its successful completion. Before starting, make sure that you have all the necessary tools and replacement parts. Also, be sure to turn off the power to the door lock before beginning the procedure. This will prevent any electrical shock or damage to the unit. Once you are adequately prepared and have all the necessary tools and parts, you can begin the repair process.

Gather the necessary tools

Gathering the necessary tools before beginning this project is an essential step in ensuring it goes smoothly. A Phillips head screwdriver and a flathead screwdriver will be needed to complete the process. An allen driver may also be required depending on the type of lock you have at your home or business. It’s possible that the company that installed your lock has special tools that are needed for the process, so confirm this with them if available. You should also have a light to better see what you’re doing if your lock is installed in a dark area, and a towel or rag to protect the finish on your door and lock from scrapes and scratches as you work.

Check the battery type

Before beginning the process of changing the battery on your Vivint Door Lock, it is important to first identify the type of battery in use. This information can be found in the owner’s manual or on the back of the device. Common batteries used in Vivint locks include CR123A and AAA. If a different kind of battery is needed, it will need to be purchased before proceeding with battery replacement. It is also advisable to purchase two batteries so another one can be kept as an emergency backup in case of sudden failure or power loss. Taking these precautions before starting will ensure a smooth process and make sure you don’t get caught off guard with a dead door lock!

Removing the Old Battery

Before you can replace the battery on your Vivint Door Lock, you’ll need to remove the old battery first. Fortunately, this is an easy task. The first step is to open the battery compartment located at the bottom of the door lock. You’ll need to use a small flathead screwdriver to remove the screws that hold the lid in place. Once the lid has been removed, the old battery can be taken out.

Remove the cover

The first step in replacing your Vivint Door Lock battery is to locate the battery casing. The casing is located on the side of your lock and may require a Phillips screwdriver to access the Door Knob. Once you’ve located the casing, unscrew the screws and remove the cover. It’s important to be careful when doing this, as some models are fitted with a spring-loaded Door Knob that can be delicate.

When you have removed the cover, you will see a battery compartment that contains three battereies – one for each of the three components of your lock (receiver unit, operator unit and pull pocket). Carefully remove each of these batteries using anti-static tools or gloves – this helps prevent any static electricity from damaging any components under the Door Knob. Set aside all components and make sure not to mix up any parts, as incorrect installation could cause damage to your lock’s electrical system.

Locate and remove the old battery

When you are ready to replace the battery on your Vivint Door Lock, the first step is to locate and remove the old battery. To do this, you should:

1. Make sure that your lock is in “Off” mode. To enter “Off” mode, press the lock button until it turns blue and release.
2. Locate the small screw on the side of your lock near the top – typically, this is an allen head type screw and can be found on either side of the product body. With a flathead screwdriver, loosen but do not remove this plug/drain screw.
3. With a pair of needle nose pliers carefully pull out old battery and discard appropriately per local disposal regulations. Batteries contain hazardous materials that could adversely impact safety if not disposed of properly
4. Once removed, install your new CR123A (3 volt) lithium battery – noting proper polarity (+/-). Replace drain/plug screw tightly in to hole
5. Press and hold power button for two seconds for activation; LED indicator will start blinking green if connected correctly

Installing the New Battery

Changing the battery on your Vivint Door Lock is an easy process. The first step is to remove the old battery from the device. Once it is removed, you can install the new battery by inserting it into the back of the device. Then, you can close the back cover of the device and the battery should be installed. Now you can test the device to make sure the new battery is working properly.

Insert the new battery

Once the battery casing has been removed, insert the new battery carefully into its compartment. Make sure that the positive and negative terminals on the battery are in line with the positive and negative poles inside the battery casing. Once you are certain that it is properly aligned, push down on the battery to secure its place in the casing. Replace any installed screw or pieces before closing it up again. With that done, your replacement is complete and your Vivint door lock should now be fully functional!

Replace the cover

Once you have firmly secured the new battery, unscrew the back cover by using your flathead screwdriver. On most Vivint door lock models, screws are located in each corner. Align the door lock back panel and press it in place. Secure all four screws with the flathead screwdriver to Cut the Key and complete the job. Be sure that the long tounge on the back plate lines up properly with the slot in the door lock’s faceplate; this is important for proper operation.
Upon completion of all steps, test your Vivint door lock by placing two AAA batteries into your remote (if applicable). Press firmly until both pieces are securely attached. Test as many times as necessary to ensure that you have not missed anything and that everything is in working order. Be sure to discard of any old batteries according to local regulations for hazardous waste disposal.

Testing the New Battery

Before you can start using the new battery for your Vivint door lock, you need to make sure that it is working properly. Testing the new battery before installation is a critical step, as it will allow you to determine if the battery is fully charged and that it is compatible with your door lock. In this section, we will discuss how to properly test the new battery.

Test the lock with a key

Once the battery has been changed in the Vivint door lock, it is important to test that it is working properly before re-installing the cover. To do this, insert a key into the keyhole and turn it clockwise. This should cause the deadbolt mechanism to rotate, locking or unlocking the door depending on its current status. If this does not occur when you turn the key, then there is likely a problem with battery wiring connections and should be returned to be fixed by a professional locksmith.

Once you’ve tested the lock successfully with a key and verified that it does indeed work properly with the new battery, simply replace any screws and covers that were removed during installation. Now your Vivint door lock has been successfully retrofitted with a fresh set of batteries and you can rest assured knowing your doors are secure.

Test the lock with a code

Once the new battery is installed in your Vivint lock, it is important to test the door to make sure that it is functioning properly. To do this, use a custom code to activate the lock. The factory settings on most models come with a six-digit pin code. To enter this code, press down and hold the number pad’s “lock key” button until all six of the number keys light up on the display. Once they are lit, press down and release each of the numbers in turn using your finger. After you have inputted the six numbers – if correct – a green light will appear above them in the display window indicating that it has unlocked successfully. Test opening and closing the door with keyless mode as well as with a key for added security before returning your new lock to its rightful place in your home for daily operation!

Test the lock with the app

Once the new battery has been installed, it’s time to test the Vivint door lock. To do this, first pair it with your home automation system in accordance with the instructions provided by your home security company or at Vivint Smart Home. After pairing the door lock to your network, you can use the Vivint Smart Home app to test that it’s functioning properly.

To use the app for testing:
1. Open the app on your smartphone
2. Select “Door Lock” from the main menu
3. Tap on “Unlock Door Lock”
4. Verify that unlocking and locking process is successful by opening and closing the lock manually
5. Once you have confirmed that your new battery is working properly, close up any screws and finish any other assembly processes necessary based on instructions in owner’s manual
