Training a Garage Door Opener with a
"Rolling Code" Feature (If Equipped)
If you have not previously programmed the hand
transmitter to the universal transmitter, see
"Programming the Transmitter" listed previously. If you
have completed this programming already, you now
need to train the garage door opener motor head unit to
recognize the universal transmitter. Refer to your garage
door opener owner's manual for the proper transmitter
training procedure for your garage door opener brand.
1. Find the training button on the garage door opener
motor head unit. The exact location and color will
vary by garage door opener brand. If you have
difficulty finding the training button, refer to your
garage door opener owner's manual.
2. Press the training button on the garage door opener
motor head unit. An indicator light will begin to
flash when the motor head unit enters the
training mode.
Note: Following this step, you have 30 seconds to
start Step 3.
3. Return to the universal transmitter in your vehicle
and firmly press and release the universal transmitter
button you have already programmed for two to
three seconds. Press and release the button again
(you may need to do this step up to three times) to
make sure that the universal transmitter has been
trained to the garage door opener motor head unit.
