4 Key Chain 2 Pack -RFID-Key -Guard

Criminals can exploit a vulnerability in keyless entry/start systems using a digital theft technique called a relay attack. The Sanji faraday bag has two pockets that are both protected and have anti-radiation capabilities. Store your credit or bank cards in one pocket and your keyless vehicle entry remote in the second pocket. After inserting the items, close the hook & loop flap for full signal-blocking functionality. Once your key fob is inside the bag, it will provide a complete signal block and prevents thieves from picking up and relaying signals. Remove the key fob from the pouch for keyless entry, starting and vehicle driving. For complete protection after exiting the vehicle and locking the doors, insert the key fob into the bag and close the hook & loop flap. Your vehicle is now safe and sound.
