Access Master Keypads

Access Master keypads use the same model numbers as liftmaster. The 377AC is the same as the Liftmaster 377LM they are interchangeable and work for the same operators just follow the numbers 977 or 877 and ignore the letters. Access master is just another division of the liftmaster brand and will match up to your garage door opener. These accessmaster keypads are color coded to line up with the learn button on the overhead motor. Press the learn button indicator light to see if a red, orange, amber, or purple light lights up. The wireless keypads should work flawlessly with any access master garage door opener once you determine what version you have.
