How do I know if the Liftmaster 371LM remote is compatable with my garage door opener?
The most surefire way to find out if your remote is compatible is to look for the learn button on the back of your garage door opener. The purple learn button (pictured) is the color that indicates compatibility with the Liftmaster 371LM. Other colors such as red or green will not be compatible without additional equipment. If you have any of these colors, you can visit Liftmaster-Remote.com to help find your compatible remote.
If you are not able to view your learn button, you can simply identify the model of an existing remote. If a remote of the same series works with your opener, then the 371LM remote will as well. To find your model number, look on the back of your garage door remote, keychain, or keypad. There will be a two or three digit number followed by a “LM”. If your remote says 371LM, 372LM, 373LM, 370LM, 376LM, or 377LM then your system is compatible with the Liftmaster 371LM remote. The same holds true for models 373W or 373P.
