How to Replace the Battery in a Garage Door Remote

Whether you've got a chain or a belt drive, a basic 1/2-horsepower model or a beefier 3/4-HP machine, your garage door opener likely has a handy, pocket-sized wireless remote. These little buggers range just as widely as the openers themselves, so battery-changing practices vary just a bit depending on whether you're working with a Craftsman, LiftMaster or Genie device, for instance. It's always best to refer to your owner's manual for specific instructions where available, but if you can't get your hands on a manual, rest easy knowing these varied gizmos do share some commonalities.

Most often, wireless garage door opener remotes draw power from a tiny coin-cell battery, sometimes called a button-cell battery. By and large, these remotes take a 3-volt 2032 lithium coin-cell battery, although some require a different 3-volt coin-cell, such as a 2016 or 2450, especially if they have extra functions such as flashing LED lights. If your remote doesn't take a coin-cell, chances are it needs an alkaline battery such as a common AA or AAA.


  • If you're unsure what type of coin-cell your remote takes, look at the old battery; it should have a number and voltage written on its face. Likewise, battery compartments often have labels indicating the compatible battery type.

Wall-mounted wireless keypads, on the other hand, most often use 9-volt batteries. In rare cases, wireless openers require compact A23 alkaline batteries, a special type of battery available at most hardware stores.
