Can You Copy a "Do Not Duplicate" Key?

Keys stamped "Do Not Duplicate" (DND) are common in offices, rentals and apartment buildings. But does the stamp actually stop someone from making a copy?

Will Home Depot Copy a Do Not Duplicate Key?

It depends on the store and the employee. Some locations refuse to copy DND keys due to company policy, while others may copy the key without checking the stamp. If you need a copy, call your local store first to confirm their policy.

What Does "Do Not Duplicate" Really Mean?

A DND stamp is a request, not a technical barrier. A standard key stamped DND still uses a common keyway, so it can physically be cut on ordinary equipment. Many locksmiths will ask for authorization before copying a DND key.

How to Actually Restrict Key Copying

For real key control, use a restricted or patented keyway, where blanks are only sold to authorized dealers and duplication requires authorization. These systems prevent unauthorized copying far more effectively than a stamp.
