Thanks Bill, Will, it looks as though that may be my best bet. I check and asked if I was wrong could I return them and they won't accept it if it'* my mistake therefore just to double check, do you think I would be better off using my ohm meter that'* not digital?
This is what I got from there web site:
How to decode a VATS key.
Decoding a VATS key is very simple, but it requires that you know how to use an ohm meter. Any multimeter will have an ohm meter and any Radio Shack, Electronic or Hardware Store can sell you one.
All VATS keys have a resistor embedded in the key blade with metal prongs protruding out of each side of the key blade. In order to read the resistance of the resistor in the key blade, place one lead of the ohm meter on one metal prong, and the other lead on the other metal prong, opposite, on the other side of the key blade. With the leads in there proper position a resistance value can be read from the ohm meter.
Once you get your reading, match the resistance value given by your ohm meter to the resistance value, in the right column, in the chart below. The value from your ohm meter will probably not match, exactly, the resistance value in the chart below, but choose the value closest to the value on your ohm meter. The corresponding code number is the identification number of your VATS key.
