Anyone have a recommendation for a thatcham approved transponder (not touch pad) type immobiliser which I can fit to my GTS? I know nothing about how they are installed etc do they rely on a door signal to show you have exited the car, or do they just auto arm once the key is removed? (I know they work using RFID etc)

There are loads on ebay ranging from about £30-£100+. Being a skint student, I would obviously prefer a cheaper one

Cheers,

Try this

I fitted one of these. Worked well and looks ok on the dash. Also can be set to over ride if you are playing around with the car and don't want to keep having to disarm it.

just leave the keys in the ignition, no one will dare take it as they'll think its a police trap car

or do what I do and have a huge number (53 in my case) on the roof!! handy for spotting your car on the telly

What roof?

I fitted a toad immobiliser to mine. Cost me £40. It is thatcham if fitted by a thatcham approved installer but mine doesnt qualify as i fitted it myself.

Well, I bought one of these:

Cheap as chips, sounds good for the money anyway. Time will tell!
