Legacy garage openers work with various brands and remotes.

Though not as common as the Craftsman, LiftMaster and Genie garage door openers, Legacy is a system commonly used in garages around the United States. Legacy garage doors allow you to program your motor to a variety of remotes, allowing for wireless entry. Sometimes, however, remotes stop working and signals are lost. To troubleshoot this situation, you can simply reset and reprogram the openers in just minutes from your garage.


Step 1

Press and hold the "Prog" button on your wireless keypad. Then press and hold the "6" key and the key with the up and down triangles. Release the buttons at the same time to reset the keypad.
