    Andy: Of course anything is possible, but my hunch is that the problem is with the electrical switch that is at the end of the key lock. In the wiring diagram, it's called D (see below). D has a series of sliding contacts that open/close as the key turns in the lock




    As shown, the switch connects directly to "J527" (not shown, but it's the device at the end of the 6 x wire loom in my picture) which is the Steering column electronics control unit. This device reads the D switch contacts and then it sends the relevant messages to various other control modules via the CAN bus (like engine turn ON/OFF)

    Here's a picture of D sitting at the end of the key-lock mechanism


    If you can get access to the cable and you have a multi-meter, here's how the contacts should operate as you move the key lock through it's 4 x positions



    Check these first - if you don't find a problem in the key-switch, then the problem can be in the CAN bus message
