This Signal Blocking Key Hider is a protective storage pouch that features a unique RFID blocking material that prevents the transmission of wireless signals, making this the ideal option to hide your spare key. The pouch securely adheres to any surface, so you can safely store your spare key in or on vehicle while preventing RFID key fobs from automatically locking, unlocking or starting ignition. Car thieves within range can use your key fob’s wireless signal to steal your car. Place your keys inside the pouch at home to stop them from stealing your signal and keep your car safe. Newer key fobs feature an anti-lockout function, which prevents you from accidentally locking your keys in your car.
