In the early to mid 90's it became compulsory for manufactuers to fit immobilisers.

Looking up your car here:- www.abi.org.uk/carinsurance/search.asp

From the list, most corsa's are T2 security rated.

T2 = An immobiliser that has been judged to comply to the Thatcham criteria.

www.abi.org.uk/carinsurance/help.asp#Security

Also see www.thatcham.org/security/pdfs/categories/PassengerCarCAT2.pdf

There is as small transponder chip inside the keyfob that talks to a reciever right next to the ignition barrel, that in turn talks to the car's ecu.

it does have an immobiliser fitted as standard. It has a chip built into the key which is probably a crypto type which cannot be cloned which is why the machine didn't recognise the chip.

If it has an immobiliser fault then the engine management light will flash indicating a problem. It has to go on a diagnostic machine to code in anoter key which will also require the immo code which should be on a car pass security card which has your key no, radio code and immo code.

Vauxhall will supply it but charge
