Hello. My name is Mark and I will be assisting you today.
When the system shows immobiliser active it means the key has not been recognised.
The first thing to do is try the spare key.
If this also is not recognised then the fault is with the vehicle.
This means the system needs to be reset using the correct diagnostic equipment.
You also have to do all the keys for the vehicle. If you only did the main used key then the spare will not work.
