Keep Foil Around Your Keys Shielding your keys with aluminum foil can improve your car’s security. Thieves now use advanced devices to intercept key signals and steal cars without needing the physical key. These devices can capture signals even if your car is parked in a garage or under a building.

Car owners are often unaware when their key’s signal is being intercepted. Thieves can quickly unlock and access the vehicle. Experts recommend using metal to block these signals, as it prevents relay attacks.

Alternatively, use a signal-blocking pouch or case designed for key fobs. These products protect your keys from unauthorized access while keeping them convenient to use.
