MONOJOY Car Anti Theft Lock Device


One of the most common ways to enter and steal your vehicle these days is to use a signal repeater. By taken the signal from your key, your keyless-entry car can be opened and stolen without issue. Enter the key signal blocker. Perfect for these keyless cars, the signal blocker works against car hacking and keeps would-be car thieves from their prize.

These are compact, easy to use (with no set up required) and extremely effective. Simply place your keys into the case and your car will be kept safe from signal repeaters and therefore the theft of your car.
