ROUND-THE-CLOCK PROTECTION FOR YOUR CAR
The Best Car Anti-Theft Device against Relay Attack
KEYLESS PROTECTOR
Keyless Protector is a non-invasive anti-theft device that protects your vehicle from relay attacks. If your car doesn’t have anti-theft protection, thieves can steal it in just a few seconds. One thief intercepts the signal from your key fob, while the other gets in the car and drives away.
Keyless Protector is an anti-theft solution in the form of a simple clip for the key fob battery, cutting off its power supply. No power means no signal, and no signal means no car theft. Installation takes just a few minutes and does not limit the key fob’s functionality like a Faraday cage or keyless etui. The Keyless Protector is user-friendly and non-invasive, unlike CAN-based systems that require soldering into the vehicle’s wiring.
KEYLESS PROTECTOR LITE
The Lite version offers the same key protection benefits in an even more compact form – a battery integrated with a microprocessor and motion sensor. Unlike the standard version, which is a clip-on overlay for the battery, the Lite version is a fully integrated solution.
Just like the classic Keyless Protector, the Lite version cuts off power to the key fob when it’s not in use, preventing it from sending out a signal. As a result, the relay theft method becomes impossible, because a powerless key cannot transmit a signal and therefore cannot be cloned.

The Relay Attack – A Real Threat
The “relay attack” is a genuine and growing threat. Thieves use special equipment to intercept and extend the signal from your key fob, even when it’s inside your home. One thief stands near your house to capture the signal, while the other stands by the car to receive it and unlock the vehicle – all without the original key.
This method allows them to steal your car in seconds, silently and without leaving a trace.

Step 1
Relay theft is a method of stealing a car by exploiting the vulnerable keyless entry system.
Although convenient, this system requires additional protection to prevent theft.
Step 2
A key fob with a keyless entry system constantly emits a signal to communicate with the car.
Thieves use electronic amplifier to extend the key fob’s signal.
Step 3
This allows them to unlock, start, and drive away with your vehicle — all without the actual key.
The relay theft method requires no force, is fast and highly effective. To a bystander, relay attack looks like a vehicle owner driving away in his own car.
