Control your gate from your car using the built-in Homelink button

If you have a vehicle with a built-in remote control Homelink and would like to use this button to control your gate, you're in the right place. Homelink is the most common manufacturer of in-car remote controls. Devices from this company are used mainly by Audi, BMW, Mercedes-Benz and Volkswagen, but you can also find them in Alfa Romeo, Jaguar, Land Rover, Lexus, Porsche, Renault, Toyota, Volvo and other brands.

Your existing remotes probably use a rolling code, but unfortunately they are not compatible with Homelink, since Homelink supports older fixed-code encoding from NICE . So you would need to

  1. Buy an older external receiver with a fixed code NICE FLOX2 and a fixed-code remote control NICE FLO2, or NICE FLO4. 
  2. Connect this external receiver to your gate operator (power supply + relay to the same input as the wired button).
  3. Set the same combination of DIP switches on both the receiver and the remote control.
  4. Pair the remote control with the car according to the car's manual.

And that's it—you can now operate the gate using the button in your car!

Note: You can then put the remote control in a drawer in case it gets erased from the car, or you buy a newer one :)
