whoops, sorry. Didn't mean to come off like that. What I meant by "land shark" is that I look for posts containing issues with GM's security then give my advise.
Yes, some people have reported decent findings with the cleaning of the ignition cyl. and the removal of unneccessary keys and junk off of the key ring. Most of the vehicles that I've bypassed though the people had tried this with mixed results and just don't want to take the chance of being stranded. Infact, I just bypassed a '99 Malibu this morning!
