Question about GMC Vehicle Parts & Accessories
Hi. You can reset the security system by detaching the negative port of your battery and then put it back. You can test also the ignition if it is bad by turning the headlights on then turn the key to start position. Headlight should go dim if the ignition is good. If nothing happens to the headlight when you turn the key to start position then you have a bad ignition.
