If you have trouble starting your 2005 Chevy Colorado due to the passlock system, resetting it is a simple task. Typically, the passlock can immobilize your car. To reset it, insert your key into the ignition and turn it to the on position and then off position three times consecutively without starting the engine. The theft system light will flash; wait for it to stop flashing, then start your engine. If you continue to experience issues with your alarm system, I suggest taking your vehicle to a Chevrolet dealership for controller inspection.
The security light on my truck remains on constantly, even after leaving the key in the on position for a while. Despite this, my truck still won't start.
To disable the 2005 Chevy Colorado passlock system, insert your key into the ignition and turn it to the "on" position, then back to the "off" position, and again to the "on" position. Wait for the theft system light to stop flashing, then promptly start the car.
I gave it a shot, but it's not functioning properly and it has a five-cylinder engine.
Follow these steps carefully to start your car:
1. First, make sure your door is open. Insert the key into the ignition but don't turn it yet. Listen for the rapid dings for about 3-4 seconds.
2. Next, turn the key to the ON position but don't start the engine. Wait for the slower dinging sound to stop and the lights on your dashboard to turn off.
3. Finally, turn the key to the START position to start your engine. I hope these instructions are helpful to someone! :-)
I thought the engine was the issue so I swapped in a new one for my truck, hoping it would start. However, it's still not starting. I heard that the passlock system might be preventing it from getting spark or fuel. Can anyone advise me on what to do next?
