Find a good locksmith. That resister in the key is old school. You probably won't find it at any quick key making machine.

You'll need to test the resistor on your existing kay. Many locksmiths can make you a new key, they just need the resistor value to know which blank to use in order to match your VATS. You can also order the correct blank yourself, and then have a new key cut. Chevy dealers can do it too, but that will cost a good bit more than the other options.

^ What he said. These keys are VERY easy to cut and don't require anything special. You can order an OEM key and then have it cut anywhere. No special cutting tool required with the VATS chip keys. Just confirm your resistance and key pellet number, order the right one, and you're ready to go.

You measure the metal part of the pellet side to side with your meter set to ohms. One meter lead to each side of the pellet. DO NOT use a harbor freight free or $5 meter. Use a quality meter. Then you use the chart to find the # of the VATs key you need to order. The blanks will be sold as #1, #2, etc.

One note - when I bought my car it only had one key and it was in really rough shape. I measured the resistance and bought a couple blanks. Then I paid the dealer the $25 fee to contact GM and get my key code and cut them. Otherwise I was going to be having a new key cut from a very worn blank. When you do that your new key is starting life as the worn key profile.

You can find keys on the big auction site too if you know the resistor value.

if you buy the correct key at any Chevy dealer....they will cut the key for free. You will need to know the key number.

I looked into buying a key online and then having it cut......but the Chevy dealer will be your cheapest source.

I bought one for my 03 on the big auction site and if you get a multi-meter put it on resistance and hold one probe to one side of the pelite and the other to the other side and hold it like that for 30 seconds ( My multi-meter need a few second to read it ) and if your car is like mine, it should read 0.523 or right around there. it's not complicated just kind of faddily. The key itself cost $21.00

Well I put a meter on my key and it read 890, does that sound right, would that mean i need a number 4 key ? Also could someone tell me what the "Big Auction Site" is ? Thanks

fleabay. Looks like a #4 per your reading. I have bought other locksmith stuff from UHS hardware online. They sell VATS keys too for under $6 each.

For some dumb reason people are afraid to say eBay on forums.

Ebay mentions were frowned upon on this site few years ago and would get your post deleted. Not sure that's the case now.....

That is a silly rule. Seen it on a few other forums too, I guess.

I measured and bought a new correct VATS key, for my 2002 for under $20 and had a local key shop cut it for $20 late last year. I just did a search and the vats key was $25 but still very reasonable. I also purchased a correct working fob (after I programmed) for under $25. They are all easy to find on line. Just pay attention to order the correct items for your specific car. I know earlier c5"s fobs have another function and are around $125.
