You think you’re protected…but you’re not!
Easy to get and simple to use devices called Relay attack units allow thieves to instantly copy your wireless keyfob signal.
It’s like you gave them their own set of keys. They unlock and start your car without the alarm ever going off.

Your car is constantly transmitting signals to see if the keyfob is nearby. When the keyfob is close enough, the keyfob will receive and transmit a signal back to the car, which will unlock and start your car.
Relay attack units copy those signals, allowing thieves to break in and drive away.
Each attack unit consists of a scanner and unlocker.
One thief stands outside your home holding the scanner, while his accomplice stands next to your car with the unlocker.
The unlocker broadcasts the car’s signal to the scanner.
As soon as the scanner picks up your keyfob signal, it immediately amplifies and retransmits it to the thief holding the unlocker, who then unlocks and starts your car.

Fobblocker is a motion sensor system controlled by a microcontroller. Its sensors are designed to cut off power as soon as motion is no longer detected. The keyfob doesn’t transmit a signal when powered off, so it can’t be copied.

Yes, if the keyfob battery is not weak or dead, and somehow FobBlocker malfunctions, by default you will be able to use your keyfob as normal. 

Absolutely! Pouches and boxes require you to:
  (1) Remember to bring them with you wherever you go,
  (2) Put your keyfob inside every time you lock your car, and
  (3) Take it out every time you unlock your car.
Only FobBlocker provides the convenience of automatic protection, so you don’t have to do anything.

Yes, Fobblocker has a motion sensor that can detect movements like banging on the window or shaking the car. This will wake up the keyfob, allowing you to unlock the car.
