Reprogramming Common Universal Transmitter Codes

To program a device to the HomeLink® transceiver using a button that has been previously programmed, follow these steps:

1. Press and hold the desired HomeLink® transceiver button. DO NOT  release the button. The indicator light will begin to flash after 20 seconds. Without releasing the HomeLink® transceiver button, proceed to step 2.
2. Position the end of your hand-held transmitter 3-8 cm (1-3 inches) away from the HomeLink® transceiver button while keeping the indicator light in view.
3. Simultaneously press and hold both the HomeLink® transceiver button to be programmed and the hand-held transmitter buttons. Do not release the buttons until step 4 has been completed. 
   NOTE:

   Some gate operators and garage door openers may require performing an alternative procedure for this step. If needed, perform the Step 3 procedure below, in the "Canadian Reprogramming/Gate Operator Reprogramming" section.

4. The HomeLink® transceiver indicator light will flash slowly and then rapidly after the HomeLink® transceiver successfully receives the frequency signal from the hand-held transmitter. Release both buttons after the indicator light changes from the slow to the rapid flash.
5. Press and hold the selected reprogrammed HomeLink® transceiver button and observe the indicator light. If the indicator light illuminates constantly, reprogramming is complete  and the device should activate when the button is pressed and released.
   NOTE:

   If the indicator light blinks rapidly for two seconds and then illuminates constantly, continue with "Reprogramming" steps 6-8  to complete the reprogramming of a rolling code equipped device (most commonly a garage door opener).

6. At the garage door opener receiver (motor-head unit) in the garage, locate the "learn" or "smart" button. This can usually be found where the hanging antenna wire is attached to the motor-head unit.
7. Firmly press and release the "learn" or "smart" button (The name and color of the button may vary by manufacturer).
   NOTE:

   Step 8 must be initiated within 30 seconds.

8. Return to the vehicle and firmly press and hold  the programmed HomeLink® transceiver button and release after two seconds  . Repeat this "press/hold/release"  sequence a second time, and depending on the brand of the garage door opener (or other rolling code equipped device) repeat this sequence a third time, to complete the reprogramming.

   The HomeLink® transceiver should now activate your rolling code equipped device.
