High Security Keys and Do-Not-Duplicate (DND) Keys
How do you stop employees from making copies of your company keys? DND and high security keys can help.

When you give keys to employee, tenants, or homeowners in a HOA, copy protection is a very real concern. In all of these situations, you don't want keys made without your knowledge. There are two primary methods to prevent key copies from being made without your knowledge: stamping keys as "DND" (Do-Not-Duplicate) and using restricted keyways.

Key Stamping
This is the least expensive option that consists of a standard key being labeled as DND (do not duplicate). Most legitimate locksmiths and key supply companies will not copy DND keys unless you can prove you have the authority to make a copy. That is, you need to prove that you own the lock that you are getting a key copy made for.

Unfortunately, besides being labeled as DND there is nothing that actually prevents this key from being copied. Getting copies made could be as simple as taking the key to an inexperienced person, such as those found in home improvement warehouses, or taking the key to someone that lacks moral character and disregards the DND stamp.

Restricted Keyways
This is a more expensive, but much more controlled way to prevent keys from being copied. Restricted keyways are keys that only registered companies own. That is, you get a lock and a key that only one company can sell and duplicate. What's more, the registered companies are normally restricted by region.

If you buy a restricted keyway at ACME locksmith, you will only be able to get copies of that key made at ACME Locksmith. No one issued a key can get copies made anywhere else and all attempts to get copies made will fail because it simply cannot be done. Companies registered with restricted keyways must honor the DND intent and only make keys for someone that has been authorized to do so. Anything less than this, and the company faces consequences. More details on high-security keyways.

Key copy protection is an important part of managing your key control and protecting your assets. ACME Locksmith offers both types of key protection. We honor DND keys regardless of the type of copy protection you have chosen. We will not duplicate a key unless you are on file with us as being the owner of the lock that the key opens or you can prove to us that you are the owner.
