Thanks. found and removed the relay so now just need to sort or reset the immobiliser if anyone can help with this. Also do you know the correct way to sort out the alarm fob so i can program this to the car. I have found a few ways that people say you should do it but none of them seem to work for some reason. I have bought a new replacement key fob do i will try again with that when it arrives with me.

I programmed two fobs using the instructions I found here on JF. It was tricky, but I finally got it to work. You have to get the timing of the steps just right.
