Keyless entry was sold as convenience. Walk up, the car unlocks. Press a button, it starts. No fumbling for keys. The trouble is that the same technology handed thieves a way to steal a car in under a minute, without breaking anything, and without ever touching your keys.
How a relay attack actually works
Your key fob is always chattering quietly, broadcasting a short-range signal. When the car senses the fob nearby, it unlocks and allows the engine to start. That is the whole system, and it assumes the fob is only close when you are.
A relay attack breaks that assumption. It takes two people and two cheap radio devices. One thief stands near your house, close to where your keys sit on the hall table, a hook by the door, a kitchen counter. Their device captures the fob’s signal and relays it to a second device held by an accomplice standing next to your car. The car believes the key is present, unlocks, and starts. They drive away.
No smashed window. No forced lock. No noise. By the time you notice, the car is gone, and to any camera it looked like a normal driver getting into their own car.
Why it is spreading
Relay equipment is cheap and easy to get. The method needs almost no skill, just two people and a bit of timing. And the number of keyless vehicles on the road keeps climbing, so the pool of targets grows every year. It is a low-effort, high-reward crime, which is exactly the kind that spreads fastest.
It also pairs with other quick crimes. The same crews working driveways at night are often the ones cutting catalytic converters from cars a few doors down. Modern vehicle theft is fast, quiet, and opportunistic.
What does not stop it
Plenty of common advice helps a little but does not solve it. A steering lock is a visible deterrent but a determined crew works around it. A traditional factory immobilizer does not help, because the relay attack fools the car into thinking the real key is present, so the immobilizer stands down as designed.
A signal-blocking pouch for your keys genuinely helps, and it is worth using. But it only works if everyone in the house uses it every single time, and one forgotten night undoes it. You want protection that does not depend on perfect habits.
The feature that actually stops it
This is where driver recognition changes the game. ScorpionTrack Secure and Elite include two Automatic Driver Recognition tags. The system expects an approved tag to be present when the vehicle is driven. If the car moves without one, as it does in a relay theft, that is an instant alert, because the thieves have the car but not your tag.
And on our top tier we go further than alerting. ScorpionTrack Elite adds automatic and remote immobilization, so the engine will not start without a valid driver tag present. That means a relay attack stops at the driveway. They can fool the factory system, but they cannot produce your tag. Prevention beats recovery, and this is the clearest example of it.
The monitoring behind it
Even with the best hardware, someone has to be watching. Our Secure Operating Center monitors your vehicle around the clock. If it moves when it should not, we contact you to confirm it is not just you before coordinating recovery. You do not have to wake up, notice the car is missing, and start making calls. We come to you.
Choosing your level
- Scorpion Go for anything without permanent power, monitored the moment it moves while armed.
- Standard for hardwired, monitored recovery on an everyday vehicle.
- Secure adds the two driver tags that catch keyless and relay theft.
- Elite adds immobilization, so a relay attack is stopped, not just tracked.
Every tier is insurance approved and includes the monitoring behind it. See them together on the products page. British engineered, protecting vehicles since 1973.
