Make a spare from a working building key

Start by checking which door the original opens. A unit key may be different from the one for a common entrance, mailroom or office. If you need copies for more than one door, list each key and the number of copies needed.

Tell us whether the original is bent, worn or difficult to turn. The key type and its condition help determine whether it can be copied from the original. For keys controlled by the building, check who can authorize copies and tell us what the property requires.

Can you copy a key marked “Do Not Duplicate”?

Bring the original and ask the property manager what authorization is required. We can check whether the key is restricted and whether we can make a copy with that authorization.

Can I copy a shared building entrance key?

Tell us whether management controls copies and what authorization you have. We can then check whether the key type is supported.

What if the original key is worn?

Describe how it works in the lock. A worn original may need to be assessed before we can confirm whether a usable copy can be made.
