How to Replace the Battery in an Automatic Garage Door Remote

Garage door remotes have a simple job; they beam coded radio signals to garage openers, giving you remote access to your garage. But even the extremely low battery draining task of beaming signals to the garage door opener can eventually lead to battery drain and the need to replace the battery. Replacing the battery in a garage door remote control isn't difficult; all you need is a coin or a screwdriver.

  • Screwdriver or coin (depending on the remote control)
Examine the back of your garage door remote. Look for screws securing the back of the garage door remote to the front. Use a screwdriver to remove the screws, and pry the garage door remote open; the two halves of the remote should come apart easily by hand. If there are no screws on the back of the remote, you will have to pry it open.

Look for the wedge groove along the bottom or sides of the garage door remote. Take a coin--a dime or quarter, depending on the size of the groove--and insert the edge of it into the groove on the garage door remote. Twist the coin, either clockwise or counterclockwise, to separate the top half of the remote from the bottom; use your fingers to completely separate the two halves of the remote.

Remove the battery from the garage door opener. Use your fingertips to pry the battery out of it's holder. Set the new battery into the battery holder in the garage door remote with the positive side of the battery facing up. Press the battery down securely into the holder.

Line up the two halves of the garage door remote, and press them back into place. If applicable, replace the screws on the back of the garage door remote.

Tips and Warnings

  • If you are unsure what type of battery you need, take the battery with you to the store when you go to buy a new one. If you're looking to order the battery online, search for the battery by the number printed on the positive side.
