Signal Blocker (Defender)

Signal blocking pouch protects your keyless car from thieves.

High tech criminals are stealing cars by extending the signal of keyless fobs inside homes of victims to fool their cars. By simply placing your car's fob inside this pouch it will block all signals and prevent this new type of vehicle theft. The pouch is a low-tech, low-cost solution.

The dual purpose pouch can block radio signals to/from anything you put inside including a mobile phone. If you want to drive without your phone dangerously distracting you, but without needing to switch it off, put it into the pouch to block calls and notifications.

This product is police approved by being Secured by Design accredited. It also won the Auto Express "Best Buy" award. See the "Description" section for videos of criminals stealing keyless cars while the owners are asleep.

Please pick a colour before adding to your shopping cart.  Don't forget to buy an extra one for your spare fob if you're unable to disable it.

Watch the CCTV video below to see how easily a pair of thieves can unlock and drive away a car in under 30 seconds.

The next video shows thieves silently steal an expensive electric Tesla car off the owner's drive once they figured out how to disconnect its charger.

How did they do that? One thief holds up a bag containing a special receiver that picks up a signal being transmitted from the car's fob. The fob could be by the front door. The signal is then transmitted from the first thief's device to the second thief's device. This thief is standing next to the car he wants to steal. The car thinks the owner is standing next to it with the correct fob and unlocks the doors and allows its "start" button to start the engine. The thieves completely compromise the car's high-tech security by simply re-broadcasting the fob's signal to within the proximity of the car's own receiver.

The BBC reported that thieves stole a £40,000 car in Southend. It took only moments as you can see in the CCTV footage in the article. (Link opens in new tab)

There are many other CCTV videos on the Internet showing how vulnerable modern cars are to being stolen if they use keyless entry and start.
