did the car work without he transponder in key key originally?
perhaps the original immo has been removed and an aftermarket one put in. In which case, youll need to find it, take it out, and rejoin the wires which have been cut. Which will more than likely be on the ignition barrel or near the fuse box. It could even be something as simple as a relay controlling the ignition like a simple immobiliser, so just try and find soemthing that isnt meant to be there...
id put money on it being the immobiliser now if not fuel pumprelay
