Vehicle Immobiliser

A vehicle immobiliser is a system that is installed into the ignition system of the car and prevents the car from easily being started without the key. With this device a tag is carried along with your keys and before attempting to start the car the tag fob is touched to a receptor mounted in the car, this disables the immobilisation circuit and allows the key to then start the car.

This is a cheaper option than a full alarm system, and the best solution if all you require is a car immobiliser for insurance. We will provide you with an MESF multi-copy document where one is provided specifically for insurance companies. Customers however, should be aware that this device will not provide protection for the cabin space, and if the vehicle is broken into no siren will sound. It is also worth noting that if your insurance company asks for a Cat 1 immobiliser then they are asking for a full Category 1 alarm system, with integral immobilisation circuit included as standard.

Thatcham Category 2

This product is Thatcham Category 2 immobiliser and is a touch immobiliser relying on the driver touching a tag to a receptor placed in the vehicle. The receptor is usually placed discretely on the dash or in an empty push switch slot, if available. The choice of placement is dictated by the interior of the car and what is physically the best option, this will mean that a hole needs to be drilled in the dash to house the receptor. Customers receive two tags, at the time of installation, and one of these can be carried on your split ring along with other keys.

If one tag is lost or broken then we recommend customers purchase a replacement from us. This is because it is necessary to have at least one active tag to disable the system before a new tag can be programmed to the immobiliser system. If neither tag is available then there is no other option but to have the immobiliser replaced by a completely new system. Should this happen to you, please remember that we will take out the old system free of charge, if a new immobiliser or alarm is installed at the same time.

Please be aware that we use different Cat 2 touch immobilisers from different manufacturers to keep costs to a minimum, (please see pictures).


* Extra Parts and Labour will incur a reasonable additional charge as some vehicles require extra time for fitting e.g. Nissan Elgrand adds £80 to any alarm system, built motorhomes may need extra installation time, and door motor fitting is charged extra on a per door basis.
