Car Key Signal Blocker Pink Pouch Guard your vehicle against technology-smart car thieves with this superb, signal-blocking key fob pouch! Modern keyless fobs carry identification chips that pick-up radio signals sent out by their car. The vehicle recognises the fob when it\'s in range and unlocks the doors. Keyless ignition systems work in the same way - enabling cars to start when the key fob is detected in the cabin. This pouch features an inbuilt, dual weave, faraday shield lining to block electromagnetic frequencies. The exterior features a faux-leather look and is pink in colour. It’s designed to stop all frequency signals being sent or received by your car fob, stopping access to your car. It’s compatible with 99% of all remote key fobs. There is also a second section in this pouch for credit or debit cards, blocking the signal from theives and to make sure that they cannot get access to your details.
