First, follow the manufacturers' guidelines for the signal blocker you use. But for all signal blockers, your vehicle's keys need to be placed inside the RFID blocking area. Some pouches have 2 or more compartments of which not all may offer protection so be careful! Close the signal blocker making sure it is fully closed. The signal blocker should now be fully functional. To get in your car or truck simply remove the keys from the blocker and away you go.
