HomeLink is an incredibly convenient feature that allows you to control your garage door, gate, and other home automation devices directly from your car’s rearview mirror or visor buttons. If you have multiple vehicles, programming HomeLink in each can streamline your daily routines. However, setting up HomeLink for two cars, especially with modern rolling code garage door openers, can sometimes present a few hurdles. This guide will walk you through the process, ensuring a smooth setup for both of your vehicles.
Tip #1: Understand Garage Door Opener Memory Limits
Many garage door openers come with a programming limit, often around seven devices. This limit includes car HomeLink systems, handheld remotes, and keypad entries. If you’ve programmed several devices over the years, you might hit this limit when trying to add a new car. You might find that your garage door opener refuses to learn new HomeLink codes, no matter what you try. It’s not a rolling limit where old devices are automatically removed.
