Lost Keys

[SGHETTO]

My 2yr old was last with the one and only set of keys to my car. Ive been searching feverishly for 2wks now, and im starting to give up hope. Does any one Know who you call or where you can go to get new keys or a new ignition switch for 98 regals with the computer chipped keys.

Your local Buick dealer would be best suited to help with this problem but it may cost a couple hundred dollars. They should have all the right tools to replace the ignition cylinder and reprogram the body control module to accept a new key.

Sorry I can't be more specific on a public forum but If you want to work this out yourself here are some things to consider.
Your car is equiped with the GM PASS-KEY II theft deterent system. In addition to needing the right key physically it must also have the right chip built into it.
The chip is a resistor of a certain value that matches the value stored in the body control module (BCM). The resistor is read by a pair of contacts when you insert the key.
If the wrong resistance is read then the fuel will be cutoff to the engine for a certain period of time.

You could have a new key made to fit the existing lock cylinder or replace the cylinder and key set with a new one. Either way, the new key has to match the value stored in the BCM unless you have access to a GM Scan Tool.
Using trial and error (and the GM service manual) and some electronics knowledge you could determine the value of the key you need and specify this value when getting the new key made.

I would think that your Buick dealer should be able to get or make a new key for you. All you should need is the VIN and proof of ownership.

If the dealer has to replace the ignition cylinder, that just cost me $420 to replace. But they should be able to get you new keys using your VIN. They cost about $30/ea.

The chip is a resistor of a certain value that matches the value stored in the body control module (BCM). The resistor is read by a pair of contacts when you insert the key.
If the wrong resistance is read then the fuel will be cutoff to the engine for a certain period of time.

I have the same system in my 96 regal. It won't allow the starter to crank the engine for 3 minutes for anyone if it doesn't have the right key in the first few tries. This is supposed to prevent theives from trying several differant keys to start your car ccording to the manual.
