Liftmaster Garage Door Remote Battery

Replacing the battery in your Liftmaster garage door remote is a simple task that can be completed in just a few minutes. By following these step-by-step instructions, you can ensure that your remote is functioning properly and that you can continue to open and close your garage door with ease.

Step 1: Gather your materials.

You will need the following items:

A new 9-volt alkaline battery
A small Phillips head screwdriver

Step 2: Open the remote.

Locate the small screw on the back of the remote and remove it using the screwdriver. The remote should now come apart into two pieces.

Step 3: Locate the battery.

The battery will be located inside the remote, usually near the circuit board. Carefully remove the old battery by lifting it out of the compartment.

Step 4: Insert the new battery.

Insert the new battery into the compartment, making sure that the positive (+) and negative (-) terminals are aligned correctly. You should feel or hear a click when the battery is in place.

Step 5: Close the remote.

Fit the two pieces of the remote back together and tighten the screw until it is snug.

Step 6: Test the remote.

Point the remote at the garage door and press the button. The garage door should open or close, indicating that the battery has been replaced successfully.

Additional tips:

Always replace the battery with a new 9-volt alkaline battery.
If you are replacing the battery in a remote that is used frequently, you may want to consider replacing it with a lithium battery, which has a longer lifespan.
If you are having trouble getting the remote to work after replacing the battery, check the battery terminals to make sure that they are clean and free of corrosion.
