    key codes for lost key

    I lost the only key given to me when I bought a used 1996 Olds Ninety-eight. Dealership cut two different keys...One did nothing; the other made the door alarm ding but would not start car. Dealership says the cylinder must have been changed.

    Does the VIN# indictate which chip MUST be associated with whatever key is cut for a new cylinder, or must the car computer itself tell the chip what its new code should be? It would be easier for me to change the cylinder at my home if the key is cut for that cylinder with a chip pre-programmed for my car. Is that how it works or must I tow it to a dealership to have the chip programmed for the new cylinder?

    The key code will tell which blank should be used. The correct blank will have the correct chip for the factory installed ignition cylinder.

    It probably would need to be programmed some how.

    Re: key codes for lost key

    Your VIN# tells the dealer what VATS key you require for the car - if the original cylinder has been changed - the dealer has no way to tell which key code to use to cut a new key to - the VATS code will be correct, but the "cuts" on the key will not be. The ignition cylinder can only be purchased "coded" with a "dummy" key blank which a new VATS key will need to be cut to.

    So you will require a new ignition cylinder #26033388
    And the corrisponding VATS key to the one your VIN indicates.

    Hope this makes sense.
