This next generation of key hider features RFID-blocking fabric to prevent transmissions of wireless signals from your hi-tech key fobs. Smart keys and smart key fobs constantly emit a signal looking to connect to a vehicle. The signal allows the doors to automatically unlock and the “Push to Start” button to work. The Signal Blocking Key Hider is designed for the many instances where you do not want to activate these features such as when hiding a spare key, unintentional unlocking of vehicle, multi-user business vehicles, preserving the battery life on the smart key fob, and preventing car theft. Simply place your smart key or smart key fob into the pouch to block the signal.
