Thought I'd post a reply just in case anyone else experiences similar problems. To recap the remote key is not locking/unlocking the car.

Following the instructions provided by Fixmycar I removed the cover to the instrument panel. Underneath it on the passenger side of the panel is sat a sensor of some sort (Cobra part No. 5460). This is connected to a larger unit on the other side of the panel (Cobra part No. 0144). Thinking that the intermittant nature of the problem pointed to a lose connection I removed all connections from the main unit and then reconnected them. To my joy in all started working again.

COngratulating myself on a job well done I put the unit back in its holder and replaced the dash cover. Just to make sure I rechecked the remote C/L and it was still working. I had to wait for a while before I needed to drive it. After that, to my great dissapointment, it stopped working.

I have now called in a independent alarm specialist to help get to the bottom of this mystery. However, if there are people out there who can help solve it as well I would appreciate your input. I feel there are enough clues to get to the root cause. So a bit of background:

Apparently, according to my friendly specialist, the Espace is not shipped with an alarm fitted in the factory, it is fitted by the importer. The alarm is designed to tap into the car's electrics and supplement the immobilizer. This would suggest that the remote central locking feature is built into the car as the remote key is Renault made. This would also suggest that faulty remote central locking would be due to the car and not the alarm.

Unfortunately, or fortunately, the whole things springs into life if I reset the Cobra alarm. How is that happening?
