Can only start car with master key - immobiliser problem
I don't have the car yet but he told me there's a problem where he can only start the car with the master key. The engine cuts out and the immobiliser light comes on if he tries it with the other key.
Faulty key or reader on the ignition coil? How do I go about fixing or replacing?
You will have to program the second key to the immobilizer's code.
What model is that car?
Check the forums for the procedure on how to program the key. I remember that it is an easy procedure
