Has anyone bypassed the passkey II security system in their car? My lock cylinder gave out, which I soldered resistors and got it to work for a month, and now it won't start again and I fear the security computer took a dump. Can't find one of those so I am trying to figure out how to bypass the whole system. Let me know it you have any ideas.

to bypass it altogether, i've seen someone make a 555 timer based circuit that made the proper wave pattern and sent it to the PCM and basically bypassed the system altogether. all you would need is a correctly cut key.
