It's most likely the ignition lock cylinder. There's two tiny wires inside the lock cylinder that must touch the chip on the ignition key. Over time these wires break and contact with the chip is lost. When that happens the security system shuts down the car. BTW, you have the VATS (Vehicle Anti-Theft System). HTH. -Jim

Even with 3 already put in? Could it be a wire that's loose in them? And if so why did Meninke didn't notice it?

Did they cut a new ignition key using the correct key blank? There were 15 possibilities. How did they determine which key blank was correct for your car? If you don't use the correct key blank the car won't start, or even crank. HTH. -Jim

YES in fact they did cut 2 blank keys using the same keys as the 1st one.If I have to get another chip how much will it cost

Here's how it works. They need to use your original key to determine which VATS key blank your car recognises (1 thru 15). Then they use the template (dummy key) that came with the new lock cylinder to cut the VATS key blank. If they don't know how to determine which key your original ignition key is, take the original ignition key, and proof of ownership of the vehicle (your driver's license and the vehicle registration) to your local GM dealer. They can check the chip and tell you which key blank you need. HTH. -Jim

The dealership asked if I had another set of keys which I do cause the ones I gave him isn't working.Now if I give him the other set and it don't work what should be next?

If they replaced the lock cylinder, neither set will turn the ignition lock to start the car. It's a differently cut key. They replaced the ignition lock, correct? HTH. -Jim

I think I'm beginning to understand what's going on. They think it's the KEY that's bad. It's NOT. It's going to be the ignition LOCK. HTH. -Jim

Here's the ignition lock. You can see it comes with a template for cutting the VATS keys. HTH. -Jim

Yes, you need a key with the correct chip in it. That's where your old key comes into play. You need to check the old key's chip and find out which VATS chip it is (1 thru 15). For example, my '94 Fleetwood is a #3. The cost of the VATS key blank will be around $10 to $25 depending on where you go. The Chevy Dealer will be more expensive but you'll be sure to get the correct one. I'd take the old ignition key, the new template, and proof of ownership to the local Chevy Dealer and let them determine which VATS key you have and let them cut the new keys. Once you have the new keys and you're SURE they work, destroy all the old ignition keys. HTH. -Jim

A key with no chip in it will NOT allow you to start the car. HTH. -Jim

No. The actual (old) ignition key has to be checked. HTH. -Jim

Yes, you have to use one of them. Preferably the one that you always used until the security system shut down. Most likely both are the same. They'd have to be if both would allow you to start the car. HTH. -Jim

Have the chip tested from one of those keys. HTH. -Jim

Taken my other set of keys to the dealer and asked if this didn't what's the next step? Well found out that that key didn't work,so they have to order another set of keys from GM. Question? Since there aren't making Oldsmobiles any more will they have any issues in getting them and how much would it cost to get theose new keys reprogramed

There's no programing involved. It's a standard GM VATS replacement key blank. But you need the correct number VATS key. I'm not understanding, your second set of keys won't work because the new lock takes a differently cut key. It's like trying to start your neighbor's car with your key. It won't turn in the lock. HTH. - Jim

If they order new keys from GM they'll have to know which VATS blank (1 thru 15) to order. Hopefully the people at the GM dealer will be able to make the guys working on your car understand what needs to be done. I'm sorry that I can't be more clear or give more information. Since this involves a security system I can't consciously give out certain information on a public forum. However, they should be able to understand what I've said enough to make the repair. Please keep us posted! HTH. -Jim
