The Signal Blocker is industry-leading frontline protection for your keyless car fobs. Not only does the Defender Signal Blocker perform as protection against theft, it also functions as a physical barrier between a driver and their phone, preventing incoming notifications and phone calls, meaning no distractions on the road, allowing you to fully focus. The pouch will also protect your device from any scratches or cracks, should you wish to store your phone in the glove box. Your car keyless entry fob emmits a short range signal that allows you to open your car without pressing any button on the fob.
