When it comes to car security, the common solutions that people come across are either alarms or steering locks.
But if we look at the most efficient car security solution, we can easily list the Thatcham Cat 2 Immobiliser above all.
This immobiliser offers a silent, effective layer of protection that thieves hate. It prevents the car from starting unless the correct PIN is entered, typically using existing control buttons.
What Is a Thatcham Cat 2 Immobiliser?
A Cat 2 immobiliser is an aftermarket engine-blocking system certified under the Thatcham Category 2 standard.
It integrates with your vehicle’s electronics via the CAN bus to halt the engine from starting if the required PIN isn’t entered.
Unlike usual alarms or steering locks, the Thatcham Cat 2 Immobiliser works quietly and does not draw attention.

Practical illustrations of the Thatcham Cat 2 Immobiliser
Below are some everyday situations where a Cat 2 immobiliser truly shines:
- Keyless relay attack: Thieves amplify the signal from your key fob to unlock and start your car. A Cat 2 immobiliser prevents them from doing so.
- Valet or keyed access: Cat 2 Immobiliser gives you ultimate control. Without the immobiliser disarmed, your car stays parked.
Each of these moments highlights why many of our customers say a simple Cat 2 immobiliser is a must-have.
Contrasting features between Cat 2 and Alarm systems:
- Stops engine starting: A Thatcham Cat 2 Immobiliser is capable of stopping the engine from ignition until the correct pin is entered. Alarms don’t do that.
- Requires user activation: While the Cat 2 immobiliser requires a PIN to start your vehicle, an alarm system requires a key for the same.
- Silent, invisible protection: The cat 2 unit works discreetly, offering a silent, effective layer of protection, whereas the Alarm systems alert the user and surroundings
