To cut the keys with the cutter, there was tags that came with the cars when new.There was a tag for the ignition,door and one for the trunk and glovebox. You copied the numbers off the tags and kept the numbers in a safe place and disposed the tags. If you had to get keys cut, you gave these numbers to the dealer and they would cross reference in the key book for the code to cut the key.I know because I did it.


Hope this will help
