Reprogramming Common Universal Transmitter Codes

Program a device to the universal transmitter (also known as the HomeLink® transmitter or the Universal Garage Door Opener/UGDO) using a button previously trained, as follows:

1. Press and hold the universal transmitter button that you want to reprogram. Do not  release the button. The red transmission indicator will begin to flash slowly after 20 seconds. Without releasing the transmitter button, proceed to Step 2.
2. Position the end of your hand-held transmitter 3 to 8 centimeters (1 to 3 inches) away from the universal transmitter buttons while keeping the red transmission indicator within view.
   NOTE:

   Some gate operators and garage door openers may require that you replace Steps 3 and 4 with the Step noted in the CANADIAN REPROGRAMMING OR GATE REPROGRAMMING procedure, which follows this procedure.

3. Simultaneously depress and hold both the universal transmitter button that you want to reprogram and the hand-held transmitter button. Do not release these buttons until Step 4 has been completed. 
4. The universal transmitter red transmission indicator will transition from flashing slowly to flashing rapidly after the transmitter successfully acquires the frequency signal from the hand-held transmitter. Release both buttons after the transmission indicator begins flashing rapidly.
5. Press and hold the universal transmitter button just programmed and observe the red transmission indicator. If the transmission indicator stays on solid  (not flashing), reprogramming is complete. The newly programmed device should activate when this universal transmitter button is pressed and released.
   NOTE:

   If the red transmission indicator flashes rapidly for two seconds and then changes to solid, proceed to Steps  6 through  8 to complete programming of a rolling code equipped device. Rolling code is most commonly found on garage door openers.

6. At the garage door opener receiver on the motor or head unit in the garage, locate the Learn  or Smart  button. This can usually be found near where the hanging antenna wire is attached to the motor or head unit. The name and color of the button varies by manufacturer.
7. Firmly press and release the Learn  or Smart  button.
   NOTE:

   You have about 30 seconds after completing Step 7 in which to initiate Step 8.

8. Return to the vehicle and firmly depress, hold for two seconds then release the reprogrammed universal transmitter button. Repeat the depress, hold, then release sequence a second time. Depending upon the brand of the garage door opener (or other rolling code equipped device), it may be necessary to repeat this sequence a third time to complete the programming. The newly programmed rolling code equipped device should now activate when this universal transmitter button is pressed and released.
