Reprogramming Transmitter Codes

WARNING: Vehicle exhaust contains carbon monoxide, a dangerous gas. Do not run the vehicle's exhaust while training the HomeLink® transceiver. Exhaust gas can cause serious injury or death.

WARNING: Your motorized door or gate may open and close while you are training the HomeLink® transceiver if the vehicle is in range of the motorized device. Do not train the HomeLink® transceiver if people or pets are in the path of the door or gate. A moving door or gate can cause serious injury or death to people and pets or damage to objects.

NOTE: If programing the HomeLink® transceiver is unsuccessful using the following procedure, refer to the Owner's Manual for the current customer assistance phone number.

To program a device to the HomeLink® transceiver using a button previously trained, follow these steps:

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.
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.
Simultaneously press and hold both the HomeLink® transceiver button that you want to train 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 you to replace this Reprogramming Step 3 with procedures noted in Canadian Programming/Gate Programming .
The HomeLink® transceiver indicator light will flash slowly and then rapidly after it 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.
Press and hold the just trained HomeLink® transceiver button and observe the indicator light. If the indicator light stays on constantly, reprogramming is complete and your device should activate when the button is pressed and released.
NOTE: If the indicator light blinks rapidly for two seconds and then turns to a constant light, continue with "Reprogramming" steps 6-8 to complete the programming of a rolling code equipped device (most commonly a garage door opener).
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.
Firmly press and release the "learn" or "smart" button. (The name and color of the button may vary by manufacturer.)
NOTE: There are 30 seconds in which to initiate step 8.
Return to the vehicle and firmly press, hold for two seconds and release the reprogrammed HomeLink® transceiver button. Repeat the "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.

Canadian radio-frequency laws require transmitter signals to "time-out" (or quit) after several seconds of transmission which may not be long enough for the HomeLink® transceiver to pick up the signal during programming. Similar to this Canadian law, some U.S. gate operators are designed to "time-out" in the same manner.

If you live in Canada or you are having difficulties programming a gate operator by using the "Programming" procedures (regardless of where you live), replace "Reprogramming HomeLink® Transceiver Codes" step 3 with the following:

NOTE: When programming a garage door opener or gate operator, it is advised to unplug the device or move the vehicle out of range during the "cycling" process to prevent possible overheating.

3. Continue to press and hold the HomeLink® transceiver button while you press and release every two seconds ("cycle") your hand-held transmitter until the frequency signal has successfully been accepted. The indicator light will flash slowly and then rapidly. Proceed with "Programming" step 4 to complete.
