This is very helpful if you want to reduce the security risks in your organization. The good thing is that there are now lots of locksmiths you can hire out there. One of their services is to ensure the security of your entire organization. However, it is important that you choose a reliable locksmith company out there. The truth is that having a "Do Not Duplicate" sign in the keys is not enough to provide real security in the place. A good locksmith company must be able to provide their consumers this kind of information to avoid false security. If you want to ensure real security in your place, you should consider investing on a patented key control system instead of just having this sign inscribed.
The other good thing about having a qualified locksmith working for your company is that you can ask to re-key the locks if you suspect any undermining of the security of your business
