Our advanced anti-theft systems make your car more secure

We like to make life easier for you - and more difficult for thieves, so we fit a range of security systems to our cars.

Anti-Theft Alarm System

If someone tries to break into your locked car, the alarm will sound and the hazard lights flash continuously. It's designed to frighten away thieves and attract the attention of passers-by.

In order to protect against theft, more and more cars are being equipped with systems that are set off and deactivated via a coded radio remote control. If an unauthorised person tries to open your car doors, bonnet or boot they will trigger the alarm. The ultrasonic system also knows if someone tries to get into your car through a broken window. The alarm's interior protection system detects movement inside the car, but a button can easily turn it off if you have to leave pets inside for a short time.

The latest generation of alarms has a warning signal that works independently of the car's own electrics, and a time-controlled alarm. Locking the car primes the alarm, unlocking the car turns it off. Some of our cars include tilt sensors which detect any change in the car's position (caused by an attempt to tow it away). Initially, the horn sounds intermittently for 30 seconds and the hazard warning lights flash continuously.

Electronic Engine Immobiliser

The engine immobiliser has revolutionised car security. It uses coding software to ensure the correct key is being used to start your car. When you insert the key it 'talks' electronically to the immobiliser and the engine which will only start if the correct key is used. So it stops the wrong user from starting your engine, and driving off.

How does it work?

When the key is inserted, a transponder in the key sends a unique code to the car, ensuring that only the correct key will start the engine. You can rest assured that the engine will not start, even if someone has a perfect copy of your key, as it will not have the right code.
