The HomeLink® Wireless Control System provides a convenient way to replace up to three hand-held radio-frequency remotes used
to activate devices such as gate operators, garage door openers, entry door locks, security systems, even home lighting. The below
steps are generic programming instructions; for Genie and Sommer garage door openers please go directly to the HomeLink website.
Additional information and programming videos can be found at www.HomeLink.com and www.youtube.com/HomeLinkGentex.
Precautions!
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. 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. It is also recommended
that a new battery be placed in the hand-held remote (garage door opener remote) of the device for quicker and more accurate
training. Some vehicles may require the ignition switch to be turned on or to the “accessories” position for programming and/or
operation of HomeLink.
Keep the hand-held remote (garage door opener remote) of the device you are programming for use in other vehicles as well as
for future HomeLink programming. It is also suggested that upon the sale of the vehicle, the programmed HomeLink buttons be
erased for security purposes. Refer to “Erasing HomeLink Buttons”.
Programming a New HomeLink Button
1. Press and release the HomeLink button that you would like to program.
The HomeLink indicator light will ash orange slowly (if not, refer to “Erasing
HomeLink Buttons.”)
2. Position the hand-held remote (garage door opener remote) 1 – 3 inches (2 – 8
cm) away from the HomeLink button that you would like to program.
Note: Some hand-held remotes (garage door opener remotes) may actually
train better at a distance of 6 – 12 inches (15 – 20 cm). Keep this in mind if you
have diculty with the programming process.
3. While the HomeLink indicator light is ashing orange, press and hold the hand-
held remote button. Continue pressing the hand-held remote button until the
HomeLink indicator light changes from orange to green. You may now release
the hand-held remote button.
Note: Some devices may require you to replace this “Programming a New
HomeLink Button” step 3 with procedures noted in the “Gate Operator /
Canadian Programming” section.
Programming a New HomeLink Button (cont’d.)
4. Press the HomeLink button that you would like to program and observe the
indicator light.
• If the indicator light remains constant green, your device should operate
when the HomeLink button is pressed. At this point, if your device operates,
programming is complete.
• If the indicator light rapidly ashes green, rmly press, hold for two seconds and
release the HomeLink button up to three times to complete the programming
process. At this point if your device operates, programming is complete. If the
device does not operate, continue with the next step of the programming
instructions.
5. At the garage door opener motor, (security gate motor, etc.) locate the “Learn,”
“Smart,” or “Program” button. This can usually be found where the hanging
antenna wire is attached to the motor-head unit (see the device’s manual
to identify this button). The name and color of the button may vary by
manufacturer.
Note: A ladder and/or second person may simplify the following steps.
6. Firmly press and release the “Learn,” “Smart,” or “Program” button. You now have
30 seconds in which to complete step 7.
7. Return to the vehicle and rmly press, hold for two seconds and release the HomeLink button up to three times. At this
point programming is complete and your device should operate when the HomeLink button is pressed and released.
In the event that there are still programming diculties or questions, additional HomeLink information and programming videos
can be found at www.HomeLink.com and www.youtube.com/HomeLinkGentex. For Genie and Sommer garage door openers
please go directly to the HomeLink website.
Gate Operator / Canadian Programming
Canadian radio-frequency laws require transmitter remote signals to “time-out” (or quit) after several seconds of transmission,
which may not be long enough for HomeLink 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. The indicator LED on the hand-held remote will go o when the
device times out, indicating that it has nished transmitting.
If you live in Canada or you are having diculties programming a gate operator or garage door opener by using the programming
procedures, replace “Programming a New HomeLink Button” step 3 with the following:
While the HomeLink indicator light is ashing orange, press and release (“cycle”) your device’s hand-held remote every two
seconds until the HomeLink indicator light changes from orange to green. You may now release the hand-held remote button.
Note: If programming a garage door opener or gate operator, it is advised to unplug the device during the “cycling”
process to prevent possible overheating.
Proceed with “Programming a New HomeLink Button” step 4 to complete.
Using HomeLink
To operate, simply press and release the programmed HomeLink button. Activation will now occur for the trained device (i.e.
garage door opener, gate operator, security system, entry door lock, home/oce lighting, etc.). For convenience, the hand-held
remote of the device may also be used at any time.
Erasing HomeLink Buttons
To erase programming from the three buttons (individual buttons cannot be erased but can be “reprogrammed” as outlined
below), follow the step noted:
Press and hold the two outer HomeLink buttons for at least 10 seconds. The LED indicator will change from continuously lit to
rapidly ashing. Release both buttons. Do not hold for longer than 20 seconds. HomeLink is now ready to be programmed at any
time beginning with “Programming a New HomeLink Button” — step 1.
Reprogramming a Single HomeLink Button
To program a previously trained button, follow these steps:
1. Press and hold the desired HomeLink button. DO NOT release the button.
2. The indicator light will begin to slowly ash orange after 20 seconds. The HomeLink button can be released at this point.
Proceed with “Programming a New HomeLink Button” — step 3.
3. If you do not complete the programming of a new device to the button, it will revert to the previously stored
programming.
