Anyone here know someone in a Vauxhall Garage?

[.Mark]

Mate has bought a write off Corsa that he is rebuilding for his daughter, it's almost done but he has had to put a new instrument pod in it and it has some sort of code to make it work. So currently not being able to find out, or put in the code the bloody thing is activating the immobiliser so the car won't start.

The garage want blood as well as limbs to do it so I figured I'd ask here to see if anyone can help - I am sure some beer tokens will exchange hands.
