Can a Do Not Duplicate Key Actually Be Copied | Easter’s
Can a Do Not Duplicate Key Actually Be Copied is a common question for Baltimore Metro property owners dealing with key duplication.

Myth vs Reality
A key stamped “Do Not Duplicate” legally and physically cannot be copied, so it is a reliable way to control who has access.
The stamp is a request to whoever is cutting the key, not a technical lock on the process. Most hardware stores and locksmiths will still cut a standard-keyway blank stamped that way if asked. The only thing that actually prevents unauthorized duplication is a restricted keyway, a patented blank that requires dealer authorization on file before anyone can cut a copy.
