Immobiliser problem
I have just bought a 2006 Focus TDci, when I bought it the seller only had one key (the 3 button fob) and the battery in it was dead. I got the car home and changed the battery, went back out to test it and it locked/unlocked the car no problem. I then went to start the car and nothing happened. The immobiliser light is flashing so I'm assuming this is preventing me from starting the car.
I have tried a couple of reprogramming tips (turn the key from 0 to II 4 times and wait for a beep then press a button and wait for another beep) and I still can't start the car.
Any help would be very much appreciated.
Thank you in advance!
