Frequently, due to some failed or intermittent sensor in the pass lock system, truck will simply not start or function. Truck will not engage the starter and if bypassed will not engage furl or spark systems. System is designed to prevent theft but upon intermittent failure, prevents normal usage. Pass lock light will appear on dash. Car will not start, ten minute periods will pass when system is supposed to reset, but often it will not which means another 10 minute wait for next reset. At times it takes up to four resets to convince the security system to accept the input. I often now carry two sets of keys to try to increase the signal strength-no idea if that helps. I would hate to be in an unsafe area or out in -20 degree weather with this piece of crap gm engineering. Dealer uses the "can't duplicate problem but we will be happy to just randomly begin replacing parts at your expense" approach. A mandatory recall to force the corporation to fix this rampant (google passlock and see the cottage industry trying to fix this piece of crap engineering) problem in gm vehicles.
