How do you program your acura to a gradge door M.B.X without a remote?

To program your Acura's HomeLink system to a garage door opener without a remote, first ensure the vehicle is parked within range of the garage door opener. Turn on the ignition and press and hold the HomeLink button you wish to program until the indicator light changes from a slow blink to a rapid blink (this may take about 20 seconds). Then, press and hold the garage door opener's "learn" button on the motor unit until the light blinks, and return to the vehicle to press and hold the programmed HomeLink button until the garage door activates. You may need to repeat this process to finalize the programming.
