Not Allowed to Make Copies

Unless you are the owner of a Do Not Duplicate key, you are not allowed to make a copy of the key(s) per the owner's orders. If a business owner fires an employee and insists on them having their Do Not Duplicate key back, then they will have to comply, and other businesses would not be able to make a copy of the key.

Now, although the owners can voice how others are not allowed to make a copy of their Do Not Duplicate key does not mean that the person will listen. This is equivalent to telling a child that they are not allowed to do a specific thing, but, curious enough, they do so anyway. Yes, there can be a difficult process to duplicate a key, but it is not impossible.

  • Name of the person that has been given permission to duplicate, and pick up, the key.
  • What key is allowed to be duplicated?
  • How many copies of the keys?
  • The key owners' contact information.

Locksmith shops are more willing to duplicate a Do Not Duplicate key as long as you are able to provide the proper authorizations. However, hardware stores are more reluctant to make duplicates, despite the chain stores selling locks, due to corporate policy.

What are Restricted Keyway Locks?

Restricted keyway locks are keys that are made to prevent someone else from creating a duplicate. In contrast to a Do Not Duplicate key, restricted keyway locks are more on the expensive side and provide more security for a key owner.

Restricted keyway locks are made, and controlled, by one specific locksmith. For someone, either the owner or someone else, to make a copy of a restricted keyway lock, then that person would need to be on the signature card if they want to duplicate.

Now, like Do Not Duplicate keys, there are major benefits to owning a restricted keyway lock. Keep reading to learn more about the four benefits to owning a restricted keyway lock.

Benefits of Owning a Restricted Keyway Lock

Restricted keyway locks provide a far more sense of security and assurance that you are in safe hands in the prevention of your keys being duplicated. Keep reading to learn about the four different benefits of owning a restricted keyway lock.

Better Security

Restricted keyway locks provide better, and more reliable, security. Owning a key, such as this, prevents thieves, or anyone else less trustworthy, from trying to duplicate your key. Since the keys would be made by one specific locksmith, it will be far more difficult for someone else to gain access to certain entry points.

With each restricted keyway lock made for you specifically, there are also specific issues and system numbers that are attached to your key. Once your specific key is made your locksmith will enter the numbers on your key into a locksmith database ensuring further security of your restricted keyway.

If your key does happen to get stolen, or lost, then it is recommended that you get into contact with your locksmith and have your locks changed or your lock rekeyed.

Easier to Keep Track

However many keys your locksmith makes you come with specific numbers on the keys and added into a database. The company, or whoever administers the keys, knows how many keys were made under your name and are kept in record. These records can provide the location of the keys and whether there were any other authorizations to make new keys if it is lost or stolen.

If you lose your key or have it stolen, then you can contact your specific locksmith to have a new key made, and authorized. After they’ve done so, then there can be a recording of that key. However, if someone steals the owner's restricted keyway lock, then your locksmith will ensure that the thief in question will not have access to that specific lock(s) for security reasons.

Control of Who Has Access

Owning a restricted keyway lock offers you to have more control and access. This allows you to have more security over who has access to what lock. So, while certain people have access to only certain locks, you will have access to all of the locks.

For example, if you only want someone to have access to a specific floor of a building, then it would be within your right to give them access to that specific floor. This kind of control would be beneficial to any restricted keyway lock owner, but, more specifically, business owners to their employees.

Limited Copies

Limited copies of the restricted keyway locks can be given out at the owner's leisure. Since the person themselves would be the owner of the key, they are the only ones who are allowed to request for duplicates to be made by a specific locksmith.

To request duplicates, the owner of the original key has to complete a form. After completing this form, and turned into the locksmith company, then the locksmith will create the keys and be given a specific number. And, lastly, after the keys are cut and given the respective number, then they are entered and stored into a database.
