The reason many business property owners seem to have the keys to their commercial property stamped with a Do-Not-Duplicate is to prevent any unauthorized duplication. This can come from random people or former employees who has a key in their possession and would like to make extra copies of it. This is a perfect way for intruders to gain entry to a business property without having to cause any damage and leave a trail. By having the keys stamped with a Do-Not-Duplicate, business property owners can pass the message to any lock shop or a locksmith that may come across a copy of their key. Its all about key control and keeping the business property as secure as possible.
The Do-Not-Duplicate stamp on a key may create an illusion of security to the business property. Most locksmith companies will ignore such stamp and treat the order the same like any other key. A professional locksmith will normally not recommend having such stamp on a key to the property as a main form of security preventing any unauthorized copies. However, patented restricted key-way lock systems are a different story. These types of locks will come with a pre-cut key from the manufacturer that require special machinery in order to duplicate and most of the time only the manufacturer itself would be able to provide a copy in a time of need.
