Running light does not work what is the problem
To reset the security code on a 2002 Chevy Trailblazer, 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. Turn the key to the "Off" position for a few seconds, then repeat the process two more times. This should reset the security system, allowing you to start the vehicle. If issues persist, consult the owner's manual or a professional mechanic.

The 2001 Chevy Blazer does have an ignition security system that is controlled by the computer in the vehicle. The light might come on because of an error that is coming up in the computer due to a key problem or an ignition problem. This is a common issue with the 2000 and 2001 Blazer.
