Protect car keys from theft and relay attacks using signal-blocking pouches, secure storage, and awareness. Modern keyless entry systems are vulnerable to tech-enabled theft, proper protection prevents vehicle theft.
Modern keyless car keys are vulnerable to relay attacks where thieves amplify your key’s signal to unlock and start your vehicle. Understanding these threats and implementing protective measures safeguards your vehicle investment.
1. Understand Relay Attack Technology
Thieves use signal amplifiers to extend your key fob’s range, even from inside your home. One device captures the signal near your door/window, while another at your vehicle mimics it, unlocking and starting your car. This happens in seconds without forced entry or alarm triggers.
2. Use Signal-Blocking Storage
Store keyless entry fobs in Faraday pouches or metal boxes that block radio signals. These inexpensive solutions prevent signal transmission when keys aren’t in use. Keep keys in blocking storage at home, work, and when carrying them in public.
3. Increase Physical Distance
Store keys as far from external walls, windows, and your parked vehicle as possible, ideally on upper floors at the back of the house. Greater distance reduces relay attack success rates even without signal blocking.
4. Disable Key Fobs When Not Driving
Some vehicles allow key fob deactivation through button sequences (check manual) or via settings in car apps. Disable your fob at night or during extended parking periods, reactivating only when needed.
5. Combine with Physical Security
Layer your security: steering wheel locks, parking in garages, driveway gates, and visible security cameras all deter thieves. Even with key access, physical barriers increase theft difficulty and duration, often causing criminals to abandon attempts.
