In any given year, Genie's lineup of garage door openers encompasses more than a half-dozen different residential models, and the company offers plenty of compatible remotes that work with other garage door brands. Luckily for users, the process for changing the batteries in these remotes is one of two straightforward methods. Remotes that use coin-cell batteries use one method, while those using AA, AAA and A23 batteries use another.
Like many common wireless garage door opener remotes, Genie's basic three-button and one-button remotes rely on a single CR2032 lithium coin-cell battery. To replace the battery, open the remote's case by inserting a coin into the slot on top of the device and using it to pry off the battery compartment cover. Remove the old battery and insert a fresh one, referring to the symbols in the compartment for proper polarity placement. Usually, the positive side of the battery -- marked with a plus sign -- faces up.
Genie's Closed Confirmed remotes, which work with the Genie Network Adapter to deliver visual and audible confirmation when your garage door closes, requires two regular AAA batteries. To swap them out, simply slide off the battery cover on the back of the remote, remove the old batteries, and align the new ones with the positive and negative polarity symbols.
The three-button remotes that work with Genie's line of Intellicode products use a special type of alkaline battery known as an A23, commonly used in alarm, keyless entry and security devices. You can track these down at most hardware stores, and changing them out is just like changing AA batteries. Slide off the battery cover on the back of the remote, remove the old battery and pop the new one in, ensuring that it's aligned according to the polarity symbols.
