Holden Astra starting problem?

Question

When the car is hot inside (engine cold) the car won't start. If you reduce temp by opening doors etc then car starts. I think its imobilser problem - car has been to dealer and they are unable to resolve. Where is the "device"that is overheating - perhaps I could spray freeze onto it or how do I bypass it so don't have the problem?
