I've done it. ISTR it was around $8-$10 for one
key. Might be $15
now. Copying pretty much always cheaper than code cuts, but you have
to find someone that can cut ACE tubular keys at all (vending machines,
etc).
Ethan,
What I tried to do was take the lock in and have them make a key. Not just copy a key...
As an aside since the Chicago Co. also made the keys/locks for the IBM 5170 is there a
catalog/code conversion book that describes how to make locks for a given 5170 key?
