To reset the Passlock system on a 2004 Chevy Colorado, first, insert the key into the ignition and turn it to the "On" position without starting the engine. Leave it in this position for about 10 minutes until the security light turns off. After that, turn the key to the "Off" position for a few seconds, then start the engine. If done correctly, the Passlock system should be reset, allowing the vehicle to start normally.
