I have a problem with the immobiliser on my vauxhall movano van 55 plate (same van as renault master). The battery went flat, now its just turning over with the immobiliser light on the dash flashing fast. Central locking works fine though. Ive tried both keys and both wont start it. It was only left a week and has never caused me a problem before.

Anyone have any suggestions before i have to have it towed to renault or vauxhall and give them a blank cheque?

I have the key code number on the information card and a 4 digit number next to that if this coulod be used to bypass it in some way?

Im due for a 200 mile trip over the weekend so need to try and get this sorted as soon as possible if anyone could help me please.

Cheers.
