Help! My only remote garage door opener is lost. How can I program a new car without it? I can drive under the garage door opener motor and I know how to operate the remote buttons in the car but can I sync them from just the motor in the garage overhead? Thank you!

There should be a button on the garage door opener that you set, which will allow you to program your remote. Once it's set, you normally have 30 seconds to synchronize or program the remote.
