Vauxhall cars with factory fitted Thatcham security systems

Vauxhall fit as standard a Thatcham category 2 immobiliser or category 1 alarm to nearly all new cars built for the UK market. Privately imported car models or older cars will have no Thatcham approved security at all so your insurance company may ask for an aftermarket alarm or immobiliser to be fitted.

"Does my car have a thatcham alarm or immobiliser?"

It's very important to check BOTH lists as some cars may have be fitted with a CAT2 first but later models could be fitted with a CAT1.

Older cars have NOT been listed below, more detailed information about older cars fitted with Thatcham alarms or immobilisers can be downloaded here as a PDF file from

Vauxhall cars without Thatcham security systems
