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. Or you could go to the dealer and have them replace the entire system for over $1000. They will have to replace the key/tumbler/hall effect switch/wiring and EVO-Passlock module to get it right.
Prior answer:
the key is worn out and neededs to be reprogramed to theft module. turn ing on with out starting for ten mins. then off and on it should program key i think. the dealer should also tell you the right way to do this. very common problem.
