hi went to get in car to take it for mot and the damn thing wont work now i cant do anything with fob the light on the fob comes on however the car does nothing i unlocked it via key but still cant start the car
if anyone can help please

Do you have the usual dash ignition lights coming up & if so is engine turning over but not starting?

Or is everything dead as in no electrics & nothing at all works ?

Entwood had this issue, it turned out to be the immobiliser chip had come loose inside the key. he superglued it back in place. Bingo! HTH :y

that was one od the first things i check was if the fob was working from every indication it is

just wondering if it is possible to disable the immobiliser
and is so would that solve the issue
also if so who can do it

How do you know it's the immobilizer stopping the car from starting?

cos the immobiliser light dont go out like it normally does

Assuming you have a standard Vx. keyfob and alarm system then you can re-sync the fob to the car by turning on the ignition and pressing and holding the lock and unlock buttons together. This will only re-set the alarm and central locking, the immobilizer is a separate system to the alarm.

The e.m.l. won't go out if the cars not running.
Is it flashing?

S'not the immobilizer stopping it from starting then.
