If your Nest door lock is running low on battery power, you’ll need to replace the batteries. Here’s a quick and easy guide on how to do just that.


Replacing the battery in a Nest door lock is a simple task that can be done in a few minutes. However, preparation is key to success in this task. You will need to have a new 9-volt battery, a Phillips head screwdriver, and a flat surface to work on. Gather these supplies before beginning the process and make sure that you understand the steps involved in replacing the battery.

Gather the necessary tools

Before beginning to change the battery in a Nest Door Lock, it is important to gather the necessary materials and tools. The list of supplies you will need includes a Phillips screwdriver, a flathead screwdriver, needle-nose pliers, tweezers or forceps, and fresh batteries for your lock. Additionally for safety reasons you may want to gather work gloves and safety glasses. Once all of the necessary supplies are gathered, you should be able to begin the process of changing the battery in the Nest Door Lock quickly and easily.

Shut off power to the door lock

Before attempting a battery replacement, it is important to cut off any power supply to the Nest door lock in order to avoid the risk of electric shock. The power can be shut off at the breaker box or by unplugging a power cord near the door. Once this is done, locate a Phillips-head screwdriver, then unbolt and remove the cover from the door lock. This will allow access to where Nest Door Lock batteries are located – usually within an interior compartment of the device. It is important that you identify and remove both of these items before accessing this area.

Removing the Lock

Changing the battery in a Nest door lock is a straightforward process, but there are several steps that should be followed carefully. The first step is to remove the lock from the door. This can be done by unscrewing the two bolts on the inner side of the door. Once the bolts have been removed, the lock should come off the door easily.

Remove the screws from the faceplate

Once you have determined that the battery needs to be changed, take off the faceplate of your Nest door lock by using a screwdriver to remove the screws around it. Keep in mind there may be a warning label covering one of these screws. On most models these are Phillips head screws and care should be taken to not over-tighten them. Once all of the faceplate screws have been removed, carefully lift off the faceplate and set it aside in a safe place until reassembly is needed.

Open the door lock

Removing the battery cover from a Nest door lock can seem intimidating. However, with a few simple steps, you can quickly complete this task and ensure that your door lock stays in good working order.

To open the door lock and replace the battery, locate the small indentation on the back of the Nest Door Lock. Just under this indentation, you will find a slot where you can insert a flat head screwdriver or butter knife. Insert either object into this slot and twist gently in an anticlockwise direction until you hear a clicking sound. This indicates that the lock is open and ready for you to remove the battery cover.

Once you’ve opened the door lock using these steps, carefully place your finger under the battery cover’s lip and lift up to release it from its position. When done correctly, it should come off without too much resistance. Now that you have removed the battery cover, it’s time to change out your old Nest Door Lock batteries with new ones !

Remove the interior assembly

The first step in changing the battery in your Nest Door Lock is to remove the interior assembly. To do this, turn off your Nest Door Lock, then begin separating it by grasping firmly and twisting. Some versions require a flathead screwdriver to hold the buttons while you twist, while others require the use of a downward motion to separate them. Have an eyeglass screwdriver and a non-conductive tool nearby so that you can unscrew any screws that are blocking your progress. Once all of the screws are removed, you can proceed to carefully pull apart the interior assembly with both hands. It should separate in two parts-the front and back casing-in order for you to access and switch out the battery.

Replacing the Battery

Changing the battery in a Nest Door Lock is a relatively easy process that can be done in a few minutes. There are several steps involved in replacing the battery, but with a few simple tools, the process should go quickly. Knowing the proper instructions for replacing a Nest Door Lock battery will help you confidently make the change yourself instead of calling for service. Let’s get started.

Remove the old battery

In order to replace the battery in your Nest door lock, you will need to first remove the old battery. To do this, start by pushing the release latch located inside the back side panel of your Nest door lock. Then pull out the battery compartment and gently slide out the old battery. Once it is completely removed, dispose of it in an appropriate manner according to local waste disposal regulations.

Install the new battery

Once the old battery is removed, take the new AA battery and insert it into the chamberthat housed the old one. Be sure that you orientate the correct side of the battery face forward. It is essential to note that if a battery is installed incorrectly, it can damage your Nest door lock and other system components.

Now, if your new battery won’t fit snugly in its chamber, this usually means that it requires further adjustment. Refer to your user manual for more information on how to readjust the chamber as needed. Finally, reassemble any protective covers or panels you had need to disassemble prior to installing your new AA battery before running a test with a working set of batteries.

Test the new battery

Now that the Nest Door Lock’s existing battery has been removed and replaced with a new one, it is important to test the new battery to make sure it is functioning properly. To test the new battery:

1.Place the interior side of the Nest Door Lock face up on a flat surface.
2.Use a flat-head screwdriver to lightly press and turn the control button located below and to the right of the latch release/autolock button until it clicks three times in succession.
3.Release pressure from the control button and press down firmly on top of it while counting to three.
4.Release pressure from the control button, wait for two seconds, then press it down firmly again and hold it until you hear four beeps in rapid succession – this indicates that your Nest Door Lock has successfully rebooted with your new battery!
5.Press any previously registered user keys against their respective registration spot on the Nest Door Lock for three seconds each successively – any green LEDs which flash signify successful enrollment in your Nest Door Lock! You’re all set now – you’ve just changed your Nest Door Lock’s battery!

Reassembling the Lock

Reassembling the lock after changing the battery is important for the proper functioning of the Nest door lock. This step-by-step guide will help you reassemble the lock and get it back to its original condition. You will need the correct tools to successfully reassemble the lock, such as a Phillips-head screwdriver and a pair of pliers. Let’s go over the steps necessary to complete this task.

Place the interior assembly back in the door lock

Once the battery has been replaced and the interior assembly is reassembled, it is time to place it back in the door lock. Start by handing the assembly into the door lock while ensuring that all components are aligned with their corresponding slots. Then, use a screwdriver to secure the assembly in place using the screws removed previously. Make sure that all screws are tightened firmly and that all components are properly secured before moving on to the next step.

After securing the interior assembly, hand in any additional parts such as strike plates, keypads, and faceplates if applicable. When inserting each part or component into its slot, make sure it fits snugly and is mounted correctly inside of the door lock. Once all parts have been placed securely within their designated slots, use a screwdriver to secure each of them in place with the provided screws. Carefully tighten each screw until all components are firmly held in place within your door lock before moving on to testing it out!

Replace the screws in the faceplate

Once the battery has been replaced, the faceplate needs to be reattached. This process is quite simple and can be completed in just a few steps.

Begin by aligning the four screws found on the back of the faceplate in their respective holes along the edge of the lock. Secure them tightly, again using a Phillips-head screwdriver. Once all four screws are in place, turn the lock slowly clockwise to make sure it moves freely in its tracks. Finally, replace and tighten the narrow assembly screw using a wrench or pair of pliers if necessary.

The battery has now been successfully replaced, and your Nest door lock is ready for use!

Test the door lock

Before installing a new battery into the door lock, it is important to test that the lock is functioning properly. First, rotate the internal knob slowly in a clockwise motion. If the internal handle moves freely and the lock opens, the problem may not be related to the battery.

Next, using a flat head screwdriver or another small tool, firmly depress the reset button located within the back of your Nest Yale Lock’s keypad until you hear or feel a click. Then, turn the knob once more to test for proper operation. Hold down on each button individually to ensure no sticking or sticking sound occurs while depressing each key. If you experience any issues after resetting your Nest Yale Lock, please contact customer service for assistance.

Offer helpful tips and advice

If you have been unsuccessful in changing the battery in your Nest door lock, we have some helpful tips that may be of assistance.

First, check to make sure the battery is properly seated in the device. Make sure all connections are clean and free of debris or other obstructions. If it still does not work, use a different brand of battery, as some batteries may not be compatible with your Nest lock. If all else fails, contact customer service for help.

Taking good care of your Nest door lock also helps ensure it works efficiently and lasts longer. Regularly check and clean the keypad to get rid of any dirt or dust that might accumulate on it over time–these materials can eventually interfere with the performance and accuracy of the device. Additionally, periodically lubricate any moving parts such as hinges or tumblers to keep them from becoming rusty or worn down over time–this can help prevent sticking when using the Nest lockset. Finally, make sure to test your keys occasionally for wear and tear-replace them if they are noticeably aged or damaged as this could cause problems when trying to open your door with them.

By following these suggestions, you should have a better chance at changing out the batteries in your Nest door lock successfully!
