Well, I tried many different ways from the owner's manual your workshop manual. I can't get any sort of reprogram to start.

Just to confirm, you are trying to start the engine and the theft light is on or flashing?

If this is the case then you most likely have an active fault or issue in the system that is preventing you from disarming the system.

Below is some detail on this system but we need to start with checking the codes.

Let us know what you find with this and we can go from there. Thanks
