You must leave the key in the ignition in the "off" spot to reset the 2006 Chevy colorado protection device, and wait 10 minutes. Verify that the safety light is blinking. The security light will stop blinking after 10 minutes, and either turn off or remain continuously on.

Its probable become a problem because of wear on the key. We have two keys and one is worn a lot more than the other and it commonly trips the anti-theft protection. It also could be related to the tumblers in the mechanism sticking. If you jiggle the key every time you put it in, you can reduce the chances of it tripping.
But if the security device is working correctly you shouldnt have to do this, mine never used to do this and the answer im looking for is why its doing this now and how to fix it
