Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, Eddie here and I will do my best to help. Do you see that small black item at the end of your key? it's a resistor. you have to measure the resistance of that key in order to make a duplicate. There are 15 possible resistance values in the GM VATS key system. and you compare your resistance value to this table. Is this what you are looking for? Let us know, Thank you.
