Coding Seat Leon keys to immobilser

[evo_ufo]

Wondering if anyone can recommend someone in the Ipswich area that could setup the immobiliser on my Seat Leon to accept the transponder in some new flip keys. I lost the original and have been working away with the non flip key, but now have a couple of spare flip keys with new transponders that I'd like coded up. Keys are already cut and are working the central locking, but not the immobiliser.

Cheers
Will
