When batteries get older, or are in remotes that are used often, the first problem that is usually noticed is decreased range. If you're noticing that everyday you have to be closer and closer to the door in order for the remote to work, it's a good idea to try replacing the batteries. At the bottom of this article, you'll find links to instructions on how to change the batteries in some of the most common garage remotes.

Why Batteries are Important in Garage Door Remotes

Every garage remote has a radio transmitter in it, while the garage door opener has a matched radio receiver. In order for the remote to be able to open the garage door, the signal from the radio transmitter must be strong enough to reach the radio receiver in the garage. As if that weren't enough, the radio receiver also has to be able to pick out the signal through all the other radio frequency noise in the area. The radio transmitter requires a certain amount of power to send its signal at full strength, which is the point at which the receiver has the best opportunity of "hearing" the signal.
