Most garage door openers sold after 1996 are Rolling
Code units.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before you begin. If you do not follow these actions,
the device will time out and you will have to repeat
the procedure.
To program up to three devices:
1. From inside the vehicle, press the two outside
buttons at the same time for one to two seconds,
and immediately release them.
2. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the "Learn" or
"Smart" button. It can usually be found where the
hanging antenna wire is attached to the motor-head
unit and may be a colored button. Press this button.
After you press this button, you will have 30 seconds
to complete the following steps.
