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.
However said it can't be bypassed is wrong. Sometimes whether you change the ignition or wire breaks whatever the case look up your vehicle wireing diagram find what color the security wire in the driver door and ground it out. I put mine on a small push button under the dash that when pressed it grounds that wire out untill I release it. Ground it out resets everything.
Thank you alot you saved me alot of trouble it worked perfect

May have a bad key. But most likely something has happened to trigger the antitheft. There is a relearn procedure that is time consuming or you can have it towed to a dealer or if you have a shop you trust they should be able to handle it. google pass lock procedure.
