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
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.
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. In the garage, locate the
garage door opener receiver
(motor-head unit). Find 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 pressing
this button, complete the
following steps in less than
30 seconds.
