What Is HomeLink?

Originally a built-in garage-door opener, HomeLink's capabilities have expanded over the years.

Whether integrated into a rearview mirror housing or built into the driver's sun visor, HomeLink's three buttons are found in many vehicles and have a variety of uses. HomeLink, which hit the market about 30 years ago, is a remote-control-focused technology that's been installed in more than 100 million vehicles.

When it was first rolled out, HomeLink helped people remotely open garage doors. While garage-door opening is still among HomeLink's current capabilities, the company has expanded its repertoire to operations such as opening and closing security gates and turning lights on or off.

HomeLink Connect, an accompanying smartphone app for compatible vehicles, enables a range of additional smart-home functions.

Homelink Can Open More Than a Garage Door

On their own, the HomeLink buttons inside vehicles are, for the most part, limited to opening and closing garage doors and gates. In some newer vehicles, however — such as certain Tesla Model 3s and Model Ys — drivers don't even need to press a button to operate doors and gates. HomeLink will automatically open the garage door when the vehicle arrives and close it after departure.

That said, because the tech uses radio frequencies to communicate with your home systems, some drivers have said they've found the range is limited to a few hundred feet — or less, if trees, the terrain, or other buildings block the line of sight.

With the HomeLink Connect app, vehicle owners can control connected devices ranging from thermostats, door locks, and window shades to more advanced tech such as home robots and smart speakers. The app also allows for programming routines that incorporate multiple devices, such as switching on your home's lights, adjusting the temperature, unlocking the doors, and disabling a security system.

Once the owner's phone is paired with their vehicle, routines can be programmed through the HomeLink app and then activated through the HomeLink buttons to avoid needing to fumble for the phone as you arrive home.

Actual programming varies somewhat by the age of the system installed on a vehicle. Check your owner's manual for specific instructions related to your vehicle and keep in mind that HomeLink may not work with all garage-door openers, either.

Homelink Is Available on Many New and Used Cars

Brands ranging from Chevrolet to Volkswagen offer the basic three-button HomeLink, though it could be standard or optional equipment depending on the automaker or model. It is also available from the aftermarket. HomeLink Connect is compatible with many aftermarket Bluetooth-equipped rearview mirrors.

Homelink Won't Alert You to a Security Breach

There is no built-in security system for the basic three-button HomeLink. It's important to remember that having HomeLink is like always having a garage-door opener in your car. That means if someone breaks into your car, they might be able to gain access to your home. In addition, on some vehicles, Homelink can open garage doors even if the vehicle isn't running.
