I'm pretty sure I read this whole thread, and no one has mentioned this yet..
say you take the whole thing apart, like Korrupt did here:
DIY: Replace dreaded steering-lock on 2009s and early 2010s.
Couldn't you just manually rotate the gear into the correct position (depressing the two buttons), then either cut the brown wire, pull the fuse, or possibly cut the motor power on the circuit board itself? (I haven't opened mine yet, going to do it tomorrow).
When the gear is in the position where the two switches are pushed in, is the mechanical lock pushed out and into the steering column? The pictures are hard to tell how the locking mechanism works, but he does say in the last picture "This piece has to be taped down or removed so that you can turn the wheel".
I know Fritz has mentioned he has some detailed instructions, but haven't gotten a response from him yet.
