The Chamberlain 371AC remote control can be programmed to open your automatic Chamberlain or Security Three-Button Remote garage door. The remote can also be programmed to turn on the garage opener's lights without actually opening the door. To use this feature, you must have a multi-function door control that features multiple buttons. All remotes come with a replaceable lithium battery that has a life of up to five years. Once programmed, the remote can both open and close the garage door from up to three car lengths away.
Program Remote Control
Press the "Learn" button on the garage door opener. This is the console that's mounted inside the garage and opens the door. The LED light will start glowing and will stay on for 30 seconds. You must complete the programming within that time. You may need a stepladder to reach the opener.
