PLEASE HELP...Need to bypass passkey 3 on 2000 Pontiac Grand Prix GTP.
I've done the unhooking of positive cable an waiting 10 mins to reset it. That
only last about a day.Then the next day after driving 4-5 miles the security
system will shut it down while driving, like its's being stolen, then i have to reset
it again for it to start and good for another day.
