Stop thieves before they start your car.

Keyless entry makes life convenient — but it also makes vehicles vulnerable. Modern car and motorcycle fobs constantly broadcast a wireless signal. That signal can be intercepted and amplified by criminals, allowing them to unlock and drive away your vehicle without ever touching the keys.

This type of crime is called relay theft, and it’s growing worldwide. Thieves don’t need to crack codes or hack encryption. With a simple signal extender, they can trick your car into believing the fob is right beside it — even when it’s sitting inside your home.

How Car Key Fob Theft Works

  • Your key fob constantly emits a low-frequency radio signal (typically 125 kHz).
  • Thieves use a relay device to capture and boost that signal — often from outside your home or near you in public.
  • The amplified signal is transmitted to a second device near your vehicle, which unlocks and starts as if the fob were present.
  • Once started, a car will keep running until it runs out of fuel, is switched off, or reaches a location where thieves can reprogram new fobs.

This means a car can be stolen in seconds — silently, without forced entry, and often driven straight overseas to be resold.
