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.
