When I bought my new ignition lock cylinder, it wasn't as expensive as the two new keys for it. But I can't rememer what I paid, if it was maybe $25 for the cylinder or so.

if you have VATS, i highly recommend going with a A/C delco lock cylinder.
i have put in the after market VATS lock cylinders & they don't last like a Delco does.

seems like a Delco is around $25.00~30.00.

Yes I agree only use delco for the ignition cylinder,but I think they are a little more pricey than 25-30 dollars.

I have an ignition switch and key out of a '92 if interested. I sold the VATS box though.

Question for you guys, I have been reading up on the VATS and how to bypass it and I decided im going to by pass it witht he resistor since Im gonna use this for a track only car. My question is could I buy a used cylinder with matching key and use that with my vats box or does everything need to match? An I called up my chevy dealer and they said $65 for the cylinder and $40 for a key. Thats just insane!

Read up on the VATS bypass some more. If you have your old key, that is the resistor size you need. After you splice the resistor in, any non-vats lock cylinder and key will work.

I thought you could still use your key and ignition that was already in the car & all you had to do was wire in the resistor???????????......... I MEAN ,, THINK ABOUT IT!!!!!!!!!!!!!!!!!!!!!!......... iF YOU HAVE TO GO THROUGH THE BULL **** OF CHANGING THE CYLINDER ANYWAY, THEN WHATS THE POINT!!!!!!!!!!!!!!

You can measure the resistence between the two sides of the pellet in the key and get the value of the resistor you need to slide into the contacts of the VATS harness under the dash. You just unplug the harness, it's the big orange sleeve with the two tiny white wires. Slip the ends of the resistor into the terminals that lead to the body and then use your existing key and cylinder to start the car as you would normally. You will probably need to build a resistor pack to create the final resistence that you need, or you can get the 14 possible resistors for installing remote starters.

Or, if you've got a gazillion miles on your car, the chances are that your key is worn out. Having a NEW GM keyblank (NOT AFTERMARKET!!!) cut to fit your old lock cylinder costs about $14 and usually will solve intermittent VATS issues.

New cylinders come with a key blank without a pellet. A new VATS keyblank with a resistor matching the original key from the car, then needs to be cut from the plain key.

I'd spend the money and replace the parts correctly, or have a non-vats memcal created for your car. Resistor packs leave too much to chance. You never know when the connections might go bad and leave you stranded.

The key must match the VATS box (the resistance, to be specific).
So unless you know what resistance was in the old key, you're out of luck without it.

The three options you got is:
- keep trying different resistor values (look it up here) and find the one that deactivates the VATS
- or you can just replace the VATS box for which you have a known key/resistance
- or you could just rip all the VATS out and disable it in the chip

The first option is the least expensive but most time consuming. And the last option is the most drastic.

Hope this helps any.
