Programming your 2015 GMC Sierra 1500 key fob to automatically fold your mirrors can enhance convenience and protect your vehicle. This guide will walk you through the process, troubleshooting tips, and frequently asked questions.

Programming Your Key Fob for Folding Mirrors

Folding mirrors with your key fob is a great feature, offering both convenience and protection. Here’s how to potentially enable this on your 2015 GMC Sierra 1500, but keep in mind that not all trims may have this functionality available.

Check Your Owner’s Manual: The most reliable source of information is your owner’s manual. It will tell you if your specific trim level supports this feature and provide instructions tailored to your vehicle.
Look for the Option in Your Vehicle’s Settings: Some GMC Sierra 1500 models allow you to enable or disable this feature through the infotainment system. Explore the settings menu related to vehicle personalization, door locks, or remote features.
Consult Your Dealer or a Qualified Technician: If the information isn’t readily available, contacting your GMC dealership or a qualified auto technician is the best way to determine if your truck supports automatic mirror folding and how to program it. They can access your vehicle’s specific build information and provide precise instructions.

Common Issues and Troubleshooting

Sometimes, the key fob might not work as expected. Here are some common problems and how to fix them:

Dead Battery: A low or dead key fob battery is the most common culprit. Replace the battery and try again. This often resolves the issue.
Key Fob Programming: Sometimes the key fob loses its programming. Consult your owner’s manual or a professional locksmith for reprogramming instructions or assistance.
Faulty Mirror Motor: If the mirrors don’t fold even after replacing the battery and confirming the programming, the mirror motor itself might be faulty. This requires professional diagnosis and repair.
Fuse Issue: A blown fuse could be preventing the mirrors from functioning. Check the fuse box for any blown fuses related to the power mirrors.
