Relay Attack Protection Car Tag Immobiliser Keyless Theft Engine Block Key Fob
In a relay attack, one thief stands near your front door while another waits by the car, boosting your key signal to open and start it. With a tag immobiliser fitted, that is only half the job. The engine also needs your LockCar tag within a short range, so the car stays put.

Relay Attack Protection: A Tag the Relay Box Cannot Replace
A relay box extends the signal between your car and the factory key inside your home. It does not give the thieves your LockCar tag. The immobiliser needs that tag before the engine runs, so a successful relay only gets them as far as the driver’s seat.
- Tag works separately from the keyless factory fob
- Engine start needs the tag, not just the factory key
- Encrypted Bluetooth code paired to your car
- Compact tag for a keyring or pocket
Short Tag Range Keeps the Signal Close to You
Relay attacks work by stretching a signal over distance. The tag range is set in the app from 1 to 5 metres, so you can keep it tight. Walk away and the immobiliser arms itself, whether the car is outside the house or in a car park.
- Tight range, starting from 1 metre
- Automatic arming when you walk away
- Automatic release when you return
- Switch the tag off with its ON/OFF button
Step by Step: How a Relay Attack Is Stopped
One thief holds a relay device near your front door while another waits by the car. The doors open and the dashboard wakes up. Then the immobiliser checks for your tag, finds nothing, and keeps the engine blocked. The car stays on your driveway.
- Relay opens the doors, but the engine will not run
- Two independent systems to beat instead of one
- Hidden module placed differently in every car
- Anti-hijack and motion detection for extra cover
Wear Your Key: Smart Watch or Smart Ring
Pair a compatible smart watch or smart ring and it releases the engine just like the tag. Your phone app stays the master control, with range, valet mode and the authorisation log all in one place.
- Smart watch or ring as an alternative key
- Phone app is the master control
- Authorisation log for every engine release
- Remove a lost device straight away
Technical data
Frequently asked questions
What is a relay attack?
Thieves use two devices to extend the signal between your keyless key and the car, so the car behaves as if the key were next to it. It is a common way keyless cars are stolen.
Will a tag immobiliser stop a relay attack?
The thieves may still open the doors, but the engine will not start without your LockCar tag in range.
Can the tag signal be relayed as well?
The tag uses an encrypted Bluetooth code and a short range that you choose, which makes relaying far harder. It also works separately from the factory key, so thieves face two systems instead of one.
Do I still need a signal-blocking pouch?
A pouch can help protect the factory key, but it only works when you remember to use it. The immobiliser protects the car automatically every time you park.
Could the immobiliser void my car warranty?
It is installed over the CAN network with no cutting of critical factory wiring, and it can be fully removed, so it should not affect the manufacturer warranty.
What if my phone is dead or has no signal?
The car does not depend on the phone. The paired tag, watch or ring releases the engine by itself.
