Are you sure it was the immobiliser? Did the light flash rapidly when you tried to start the engine?

The reason I ask is that there are often problems with the top dead centre sensor which cause the same sorts of problems

Google for 'Renault TDC sensor fault' and see if any of it sounds familiar. It's very cheap and easy to fix if it is the problem.

as both have said,seems like a sensor problem.

sounds stupid but we had an identical fault on a megane scenic a couple of years ago. Turned out to be nothing more than a poor negative connection to the battery

some of the older renaults central locking/immobiliser systems were infra red and they had some probs with them, not sure if this is the system on your car maybe someone on here could know??
