Before programming HomeLink® to a garage door opener or gate operator, make sure that people and objects are out of the way of the device to prevent potential harm or damage. Your motorized garage door or gate will open and close while you are programming HomeLink. Do not program HomeLink if people or pets are in the path of the door or gate. A moving garage door or gate can cause serious injury or death to people and pets or damage to objects.
Vehicle exhaust contains carbon monoxide, a dangerous gas. Do not run the vehicle's engine while programming HomeLink. Exhaust gas can cause serious injury or death. When programming a garage door opener, it is advised to park outside of the garage.
Do not use HomeLink with any garage door opener that lacks safety stop and reverse features as required by U.S. federal safety standards (this includes any garage door opener model manufactured before April 1, 1982). A garage door that cannot detect an object signaling the door to stop and reverse - does not meet current U.S. federal safety standards.
If programming a garage door opener or gate, it is advised to unplug the device during the HomeLink programming and also if performing the "cycling" process to prevent possible motor burn-up.
- For first time training, press and hold the two outer HomeLink® buttons, releasing only when the HomeLink indicator light begins to flash, which may take up to 20 seconds. (Do not perform this step when training the additional HomeLink buttons.)
- Position the hand-held transmitter 1-3 inches away from the HomeLink surface, keeping the HomeLink indicator light in view.
- Using both hands, simultaneously press and hold the desired HomeLink button and hand-held transmitter button. DO NOT release until the HomeLink indicator light flashes slowly and then rapidly. When the indicator light flashes rapidly, both buttons may be released. (The rapid flashing indicates successful training.)
- Press and hold the trained HomeLink button and observe the indicator light.
- If the indicator light is solid/continuous, training is complete and your device should activate when the HomeLink button is pressed and released.
- If the indicator light blinks rapidly for 2 seconds and then turns a solid/continuous light, proceed with Steps 5-7 for a rolling code device. A second person may make the following steps easier. Please use a ladder or other device. Do not stand on your vehicle to perform the next steps.
- At the receiver (motorhead unit) in the garage, locate the "learn" or "smart" button (usually near where the hanging antenna wire is attached to the unit). If there is difficulty locating the button, reference the garage door owner's manual.
- Press and release the "learn" or "smart" button (the name and color of the button may vary by manufacturer). NOTE: Once the button is pressed, you have approximately 30 seconds to initiate the next step.
- Return to the vehicle and firmly press and hold the trained HomeLink button for two seconds and release. Repeat the "press/hold/release" sequence up to 3 times to complete the training process.
