I installed the bypass kit on my 02 with no problems. Been running great for several months now.
The kit came with a cigarette lighter adapter to temporarily power the lock and move it to the disengaged position before installing the bypass. I couldn't get that to work, so per the instructions, I just powered the car up, disengaged the lock, then disconnected it. This got me a fault code which was easily cleared, also per the instructions, by removing a designated fuse in the fuse box.
All in all, it took less than an hour to install this. Much piece of mind for me.
