Liftmaster 373LM  3-Button Remote Control

Our basic 3-button remote control isn't so basic. It can operate up to 3 garage doors or gates, and/or turn your garage door opener lights on/off. You can also use it as an extra remote control to turn on lights or small appliances inside your home – all from the comfort of your car. It features Security+® rolling code technology that sends a brand new code every time it is used. One 5-year 3-volt battery is included.  

The MHz frequency of your garage door opener will determine what remote controls will work with your system.

The Liftmaster 373LM is one of Liftmaster's New Frequency (315Mhz) transmitters. It is not compatable with the old frequency receivers (390Mhz). Be sure to check the frequency on your receiver or working transmitter. Note the symbol on the transmitter. It is different from the old frequency.
