You can reset the 2002 Chevrolet blazer security system by removing the security system fuse. Keep the fuse out for 10 seconds and replace it to its original slot. Place the key in the "Run" position, but don't start it. Walk away. Come back in about 20 minutes. Turn off the key. Start the Blazer. You're done.
