Frequently Asked Questions
What is HomeLink® Wireless Control System?
HomeLink is an integrated transceiver (a transmitter and receiver) that can be programmed to activate Radio Frequency (RF) devices such as garage door openers, estate/community gates, entry door locks, home/office lighting, or other RF devices.
HomeLink is compatible with radio frequency devices operating between 288 and 433 MHz. Select 2007 and newer vehicles are compatible up to 433 MHz.
How does HomeLink work?
By means of a simple programming process, HomeLink learns the codes of your original remote control. Working closely with manufacturers of automatic door opening systems and radio equipment, Gentex has engineered HomeLink to operate systems that use either standard or rolling codes.
How can I get HomeLink?
HomeLink is packaged as a standard feature, bundled within a specific trim level, or as an option on most new vehicles.
You can also purchase HomeLink as an aftermarket product. Click here to learn more.
I can't program my HomeLink.
First try the following troubleshooting tips:
- Check the frequency of the device’s handheld transmitter (usually found on the back). HomeLink is compatible with radio-frequency devices operating between 288-433MHz.
- Put a brand new battery in the handheld transmitter. During the programming process, the battery strength of an older battery will drain, decreasing the strength of the signal sent to HomeLink. A new battery will ensure a strong signal.
- Retrain HomeLink holding the handheld transmitter at different distances and angles from the HomeLink button you are trying to program. Try 4-6 inches away, and at a different angle.
- Cycle the handheld transmitter during programming: Press and hold the HomeLink button while you press and release the handheld transmitter every 2 seconds until the indicator light changes from a slow blink to a rapid flash.
- To verify HomeLink has programmed, press and hold the HomeLink button and observe the indicator light:
- If the indicator light remains solid, it has picked up the signal and should operate the device.
- If the indicator light blinks rapidly for two seconds and turns solid, HomeLink has successfully picked up the rolling code signal. Please follow the rolling code instructions outlined in the "Programming a garage door opener" section to complete the process.
- If the indicator light remains a slow blink, HomeLink has not picked up the signal from the handheld remote. Try programming the button again or choose another button to program.
Range troubleshooting tips:
Range issues can be caused by interference near the vehicle or home or due to the use of older batteries in the original transmitter during programming.
- Put a new battery in your handheld transmitter. Training the HomeLink® takes more power from the battery than when you push the button to open the door. Sometimes by putting a new battery in the handheld transmitter, it does help pick up a better signal and increases the range.
- Retrain the HomeLink at different distances and angles. Start by holding the handheld transmitter 3-4 inches away, then 5-6, and even 6-8 inches from the buttons. Sometimes this helps pick up a better signal to HomeLink.
- Try a second transmitter with new batteries.
- Straighten the antenna wire that hangs down from the garage door opener motorhead.
What other capabilities does HomeLink have besides operating garage doors?
HomeLink will operate home/office lighting, small appliances, Radio Frequency (RF) door locks, and estate gates.

How do I program a pre-1982 garage door opener?
As long as the garage door opener is in the same frequency band (288-433 MHz), HomeLink® can be programmed to this older unit. However, frequencies of some older openers can shift outside of the HomeLink operating band, and become incompatible. The best way to program an older garage door opener is: 1) Put new batteries in the original transmitter and 2) Hold the original transmitter between one and three inches away from the HomeLink surface until HomeLink learns the signal (refer to our programming section for complete instructions).
If HomeLink has not trained within a few seconds, position the original transmitter at different distances and angles.
If these suggestions do not work, you may have a problem with the garage door opener itself. If you chose to contact a garage door opener service technician, be aware that, under FCC regulations, they or anyone else are unable to service the device if it was manufactured before 1982. Many garage door openers manufactured before 1982 do not have the safety stop-and-reverse feature which is now required by law. Some states (NY, IN, CA, MN) require service technicians to totally disable the opener if they find it to be malfunctioning.
My garage door opener doesn’t have a handheld transmitter. Will HomeLink still work?
No, you have to have a handheld transmitter or wireless keypad to program HomeLink.
How do I use my wireless keypad to program HomeLink?
The wireless keypad needs to be taken off the wall and brought into the vehicle. When programming the signal into the HomeLink button you will put in your pin number to activate the garage door and hold down the enter button simultaneously holding down the HomeLink button you would like to program. Hold both buttons down until LED light flashes rapidly. Continue with regular programming instructions.
What and where is my learn button?
The learn button is the button located on the garage door opener motor that is used for programming the remotes and keyless entry. It is usually located right above the antenna wire that is hanging from your opener. It may be under the light cover.
What is a Compatibility Bridge and why would I need one?
The HomeLink Compatibility Bridge Kit is designed to allow compatibility between a newer Chamberlain, Sears Craftsman, or LiftMaster garage door opener fitted with a yellow antenna wire and the HomeLink system in your vehicle. These garage door openers were manufactured in 2011 or later. If your opener does not have a yellow antenna wire or is not one of the brands listed above, please consider purchasing a Universal Receiver to ensure compatibility.
What is a Universal Receiver Kit and why would I need one?
The Universal Receiver is a radio frequency device that allows the HomeLink® in your car to communicate with your one, two, or three stall garage door opener. Included is a handheld transmitter to assist with programming your HomeLink. This kit is for owners of HomeLink-equipped vehicles whose existing garage door openers are not currently compatible with HomeLink. This kit, when installed in the garage, allows your HomeLink-equipped vehicle to operate your garage door. This kit will NOT install HomeLink on a vehicle that is not already equipped with HomeLink. If you have a newer Chamberlain, Sears Craftsman or LiftMaster garage door opener fitted with a yellow antenna wire, please consider purchasing a HomeLink Compatibility Bridge Kit to ensure compatibility.
When I programmed HomeLink, why did all other transmitters stop operating my garage door (handheld transmitters, exterior button panel, etc)?
You may have pressed the learn button on the garage door opener for too long of a duration which clears out all programming. The learn button should be pressed and released like a doorbell. Then you have 30 seconds to return to your vehicle to complete the programming process.
During the programming process, why doesn’t my HomeLink accept the signal from the handheld transmitter and the HomeLink light keeps blinking slowly?
Put a brand new battery in the handheld transmitter. During the programming process, the battery strength of an older battery will drain, decreasing the strength of the signal sent to HomeLink. A new battery will ensure a strong signal.
Do I have to clear the memory on the HomeLink between each button that I program?
No, when you are programming a 2nd or 3rd button on the HomeLink you will want to make sure to skip the first step. Do not hold down the two outside buttons until you get a rapid flash. This will clear the button you just programmed.
I recently installed some LED light bulbs on my garage door opener and noticed a loss of range or intermittent operation on my remote opener/HomeLink about the same time. Are the two items related?
Yes, certain brands or types of LED bulbs may cause interference with the radio signals used for operating your garage door, and impact the range of your garage door remotes or HomeLink. To solve this issue, it is recommended you use an LED bulb approved by your garage door manufacturer. Visit your garage door manufacturer’s website for more information.
During programming, it is possible that garage doors, gates, or other devices may operate. For this reason, make sure that people and objects are clear of the garage door or other devices to prevent injury or other potential harm.
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.
Garage door opener motors manufactured after 1995 may be equipped with rolling code protection. If this is the case, you may need a stepladder or other sturdy, safe device to reach the “Learn” or “Smart” button on the garage door motor.
It is suggested that upon the sale or lease termination of the vehicle, the programmed HomeLink buttons be erased for security purposes.
