It is probably not the anti theft system if it cranks over fast then slow it is your timing chain. If you want to try resetting the anti theft system disconnect the battery cables for 24 hours and reconnect them.

1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the PASSKEY system to recognize your key.

2005 Chevy Colorado anti theft My truck shows the anti theft light on and it will not crank, how do I reset the computer?


There is no magical reset procedure , you have it scanned for DTC'S -diagnostic trouble codes ! Then tested and repaired . Which means you have to take your vehicle to a qualified repair shop .

06 trailblazer trouble with anti theft system, I think, starts right up then other times the anti theft light comes on and it won't start. can try it 2-4 hours later and it starts right up????


The first thing to do get it checked for DTC'S - diagnostic trouble codes . Not at auto zone or any other parts store , you want to have full scan of all the modules on the car. Don't know how much you know about automotive electronics , computer controlled systems etc.... Your vehicle has at least 10 modules (computers ) on board , there all talk to each other on a serial data network . C.A.N - controller area network . Or in the case of GM it has it's own . GMLAN -
How to Diagnose Controller Area Network CAN When you turn that ignition switch to start it is an input to the computer ,be it the PCM or BCM ..
