Do car key signal blockers work? 

The technology in a car key signal blocker works by isolating the key fob radio frequency signal. A key signal blocker is commonly used to protect against devices that are used by thieves to boost a key fob ID and gain entry into cars without the key. The benefits of a key signal blocker are to isolate radio frequency signals from the key fob, prevents car theft and can be used for all contactless/fob-style accessories.

Car security is essential to prevent thieves from stealing your car whether it’s at home on the drive or parked out in public. Our collection of car security products is a great addition to your car for added peace of mind.
