Copying a key that says "do not copy"
I am moving into a condo (so the unit is owned by one person, and a management company handles the building and grounds) and I would like to have a set of spare keys made. I live alone and would like to have a friend of mine have the extra ones in case of an emergency because the management is not on-site or 24 hour and the owner lives out of state. When I got the keys, the owner told me to make copies of the keys if I needed to. Later, when I looked at them, I noticed that the building key says "do not copy" on it. The management will not give me another key unless someone else moves into the apartment, and it would cost me a lot of money to get a replacement key if I just said I lost my original one.
Is there a way to get copies of this key made? Are most hardware stores really lenient about this?
