If you think someone knows the code to open your garage door or your remote has been stolen, it is time to change the code on your garage door opener. Newer garage door openers have a keypad in addition to the remote, which makes it slightly easier to change the code. If you have an older garage door that is only operated by a remote, you must physically move the switches inside the remote and door opener to change the code.
Garage Doors with a Keypad
Place a ladder beneath the garage door’s motor unit to reach the unit.
Press the learn button located on the side of the motor and hold it down. Release the button when the light beside it goes out to remove the old code from its memory.
Push the learn button on the motor again, so its light comes on again. Enter the desired code on your keypad on the garage wall. The motor unit’s light blinks to indicate that the new code has been accepted.
Press the learn button on the motor once more, so the light on the motor lights up again. Press a button on your remote. The motor unit’s light blinks to indicate the remote has been programmed with the new code. Repeat this step to program all other remotes.
