short answer is that the immobiliser does not need resetting. you have a different problem. give us loads of details and previous problems etc and we will try harder, you are in the right place but we have nothing to go on so far...

this suggest a fault with the key or the relevent module on the car. is this the flip out bladed key or the non bladed key? i am guessing you have only one key, if you had another you would have tried it, right??

You can do a re sync,,the details are in the DIY something like putting the key in the ignition and pressing any button on the key, do take a read. I take it it is the flip out key

exactly what i thought, but i am trying to walk away from this one, i think it is going to be 'one of those problems'. the o/p is not giving much away, but i am sure there is more to it than we have been told so far.
