Summary:
Modern key fob ignition systems do more than just start or unlock your car. Many key fobs come with additional features that enhance convenience and functionality.
Hidden Features of Key Fobs
- Lower Windows & Open Sunroof: Many fobs let you lower all windows by pressing the unlock button twice and holding the second press.
- Fold Mirrors: Some vehicles fold mirrors when you hold the lock button for 10 seconds.
- Seat Memory: Certain models assign a number to each fob, allowing automatic seat adjustments based on who’s driving.
- Radio Presets: Fobs can also store individual radio presets for each driver.
- Summon Vehicle: Tesla fobs can move the car forward or backward remotely. “Summon” must be enabled first from the vehicle’s center screen.
- Extend Fob Range: Holding the fob to your chin can boost its signal due to your body’s conductive properties, according to tech critic David Pogue.
Common Issues & Solutions
- If Your Key Fob Stops Working: Replace the battery—this is usually the root cause.
- If You Lose Your Fob: Contact your dealership or a locksmith for a replacement.
