While I am not aware of a way to bypass or circumvent the security system, resetting the system should fix the problem if it was somehow tripped. This can be done by diconnecting the battery (while either positive or negative side will work but I would recomment negative because of less sparks on disconnect) for a period of time (usually 10-12 seconds but I would leave it disconnected for a minute or two).

The Passlock security system is the problem. Should be recalled. Go here http://newrockies.com/?ap_id=craigpeate for a module to bypass the system completely. The resistor workaround at the key isn't always the only problem. I tried it on my 99 Suburban and it didn't do any better with the resister bypass. You need to eliminate the entire security system. Buy the pro module for $179 plus shipping and save yourself the hassle of dealing with it ever again.
