Default Stolen Keys

My keys were stolen about a month ago for my 1990 Vette.

The lock smith wants $400.00 to replace the ign. loch and make new keys for the door.

A friend thinks I can get new keys from the Chevy dealer using the Vin#.

Is there a simple way to get a new set of keys or am I destined to pay the lock smith?

Thanks

Ralph

I know the ign. key number.

If you just get new keys whoever has the stolen ones can still come and take the car

Have you tried getting new or used lock cylinders that come with keys?

The dealer can probably make keys for your car. They must keep the info on file for a long time because they made me a new key for my 1989 Silverado. All they needed was the VIN.

Having the key number any GM dealer can make you a new ignition key that has the correct code reading pellet.
You mentioned that the lock smith was only going to make you new keys for the doors. I would want new locks for the doors that would come with new keys so the key thief could not un-lock your doors with his stolen keys.
Leaving your car outside the garage using a new key for the cars ignition, there are ways/means to keep your car from starting with your stolen ignition key.

Changing the ignition & door locks is not very hard to do
The door panels are very easy to remove.. the steering wheel needs a 2 slot puller & a lock ring compressor
If you don't know your key resitor value...get your Ohm meter out.. there will be a ignition lead under the dash.. usually Orange & white wires... Test both sides till you get your Ohm value

Key code information is spotty at best from GM. When I lost the only set of keys to my 91 a few years back GM had the the cut on file but not the VATs code. I'd still try that route because if the info is on file it will obviously be the easiest way to get the car running. However, if its not on file you're gonna have to either pay the locksmith or get to work in the garage.

I chose to do it myself. It wasn't really that difficult, just a little time consuming. You'll need to get a new ignition lock cylinder and install it. It will come with a generic key with no VATs pellet. Once you get it in you'll be able to turn the ignition, but obviously it won't start without the VATS chip. You then need to duplicate each of the possible VATs values and try to start the car. I used a cheap potentiometer to set each value so I didn't have to mess with resistors. Once I got the car to start I took the VATs code to the parts counter and had them make me a couple ignition keys. The moral of the story I learned is make sure you have spare keys for your car.

Well I took the VIN # to the dealer and he cut me a new key.

Works good.

I had a duplicate key made about 6 months ago and wrote down the number.

It was $29.82 for the key and $20 to access the GM records and $3.51 to cut the key.

By the way they stole my keys that were in my pocket and I happened to have the 2nd set in my briefcase which was also stolen.

Now I'm thinking a 3rd set in the gun safe.

Will the insanity ever end?

Ralph

P.S. Thanks for the tip on the Helms manual.
