    Default Vats Key Code

    Do I have to go to the dealer to get the resistance for my 86 ignition key, or is it wriiten down somewhere in the car? Do dealers charge for this service? Will a good key maker place be able to do it? Thanks,--John.

    I think a good key shop or locksmith can measure the resistance value of your key. The local Wally World or parts stores can't do it. The resistance value is then matched to a table of key numbers to get the right one for your ECM. I think there are 15 different ignition key blanks with varying resistance values. The resistance value must match what the computer (VATS) sees in order for the car to start.

    I would go to a dealer simply because they would have a key in stock. You should buy a spare key at the same time.
