Your car key fob might seem harmless, but thieves can exploit its signal to steal your vehicle—without ever touching your keys. This scam, called a relay attack, happens fast and leaves no signs of forced entry.
How Thieves Hack Your Key Fob
Criminals use handheld devices to intercept your key fob’s signal, even from inside your home. One thief stands near your door or window, capturing the signal. Another stands by your car, relaying that signal to trick the vehicle into unlocking and starting. Within seconds, your car drives away—with your key still in the house.
The Aluminum Foil Fix
A simple solution? Wrap your key fob in aluminum foil. The foil blocks the signal, preventing thieves from intercepting it. For better protection, use a Faraday pouch or metal box. These work the same way but look less like leftovers.
Extra Security Measures
- Disable wireless signals (if your car allows it).
- Store keys away from doors/windows to reduce signal range.
- Use steering wheel locks as a visible deterrent.
Stay One Step Ahead
Push-to-start cars are convenient but vulnerable. Don’t wait until it’s too late—shield your key fob today. A little foil could save you from a big headache tomorrow.
