One that is licenced to a particular locksmith is a restricted keyway. This implies that the key blanks cannot be accessed by someone else in the country, so no copies of the keys will be possible unless done through your appointed locksmith.You may want to check out Commercial Locksmith for more.
Restricted keys and keyways are one way for a commercial locksmith to provide an organisation with access control, and there are other ways. One could have electronic locks installed, for instance. These locks require a combination or code to be known to the users in order to gain access. Biometric locks that include a fingerprint or a retinal scan are also available. Another choice is key fob systems; these enable everyone to bring some form of badge to scan to gain entry. The benefit of creating an audit trail is provided by all three of these methods. An audit trail may show who and when has come or gone.
The repair and/or installation of emergency escape systems is another useful service that a commercial locksmith may offer. If the projected occupancy is above a certain amount in most commercial buildings, based on the square footage of the location, then a single function exit system is required by law. If it is the back door to a restaurant, for example, and the door is considered an emergency exit, then a panic bar must be fitted with the door. A panic bar helps a person to gain exit in the case of a fire by just bumping up against the device. If the door is an exit to a small office or store, such as a unit in a strip mall, then a single function lock might be the best option. These locks incorporate a deadbolt as well as a lever handle; all locks unlock simultaneously until the lever handle is pressed back. These locks are advantages over a panic bar because they provide the protection of the deadbolt while retaining the specifications for emergency egress.
