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.
3. Immediately return to the
vehicle. Press and hold the
Universal Home Remote button
that will be used to control the
garage door until the garage
door moves. The indicator light,
above the selected button,
should slowly blink. This button
may need to be held for up to
20 seconds.
4. Immediately, within one second,
release the button when
the garage door moves.
The indicator light will blink
rapidly until programming is
complete.
5. Press and release the same
button again. The garage door
should move, confirming that
programming is successful and
complete.
To program another Rolling Code
device such as an additional garage
door opener, a security device,
or home automation device, repeat
Steps 1 through 5, choosing a
different function button in Step 3
than what was used for the garage
door opener.
If these instructions do not work,
the garage door opener is probably
a Fixed Code unit. Follow the
programming instructions that follow
for a Fixed Code garage door
opener.
