The best solution you'll get from books at www.reliable-store.com

These are books containing info on repair, service, troubleshooting, parts info, assembling dissemble, removal, error/fault codes, wiring diagrams and everything on any vehicles cars, atv, trucks. forklifts, boats, excavators etc

According to RepairPal: "the car wont start due to anti-theft system, it will say wait three minutes then start, but repeat this process 4-5 times - Visitor"

They say there are 75 reports of: "Problems with the anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The the key and ignition lock cylinder must be replaced to correct this condition."

Will the car start? If you can start the car, that may disarm the system.

The theft light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hot wired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

check battary

Then a problem is occurring in the system, have the dealer scan it and see what is keeping it from starting. It may not be the alarm system, other problems may be occurring.

YOU CAN CRANK VECHICLE BY PUTTING KEY IN THE IGNITION SWITCH IN ON POSITION FOR 10 MINUTES UNTIL SECURITY LIGHT TURN ITSELF OFF.THEN TURN OFF IGNITION SWITCH FOR 5 SECONDS THEN START ENGINE.YOU CANT BYPASS THE THEFT SECURITY SYSTEM BECAUSE ITS A FEATURE THAT CAME WITH TRUCK.THEFT SECURITY SYSTEM IS CONTROL BY BCM AND PCM. IF YOUR IGNITION KEYS AND SWITCH IS FAULTY ALSO THE BCM THEY ALL HAVE TO BE REPLACED AT DEALERSHIP AND REPROGRAMMED CANT BYPASS SYSTEM YOU HAVE TO GET IT FIXED.
