This refers to an entire class of products made for public areas. These are often required by fire inspectors in locations where groups of people are meant to gather. These are only installed on out-swinging doors, and must open freely when anyone presses against the door. They can include exit alarms. Some people might call them “crash bars.” There are many issued to consider when selecting and installing panic devices. These include whether the door is used frequently or virtually never; whether the door is insulated as a fire and heat barrier (a fire door); and whether access from outside is needed. The height of the installation and type of device required is also regulated. A professional locksmith should be familiar with local requirements and can select and install the right product to protect your property and ensure the safety of all guests.Pick
This refers to both a method for opening locks without the key and for the tools used to do this. Possession of burglary tools is illegal in many states. Also, locksmiths spend years cultivating a knack for picking locks. Simply having the tools does not guarantee success. Also, some locks are more resistant to picking than others. See also high-security.Progression
This refers to a method of fitting a key. This is a common method used when one lock from a vehicle provides only part of the information needed to make a complete working key. It usually involves the use of a chart or computer software that helps the locksmith generate a list of the possible keys for the lock(s). The locksmith can then make a series of keys to try. It sounds complicated, and it is. But professional locksmiths know that it can save hours of disassembly work!Rekey
This refers to one of the most common services provided by locksmiths. It generally entails disassembling a lock to replace the “tumblers” inside. Once completed, the lock requires a different key to operate than before. This is done to house locks when people move, divorce, are robbed, etc. Businesses rekey frequently when any key-holding employee quits or is fired. Body shops and auto dealers have new replacement locks rekeyed to match their customer’s key before installing them in the vehicle. If a lock must be replaced on a home or business, often it can be keyed to match the other locks on the building.Restricted key system
This refers to various products available from professional locksmiths. If you buy such locks, you can be sure that no unauthorized duplicate keys will be made. Many businesses and institutions utilize such systems. If an employee’s key from a restricted set is returned upon their resignation, no rekeying is necessary (this can save thousands of dollars!). Other popular applications are neighborhood swimming pools, tennis courts, clubhouses and fitness centers. This allows the management to issue keys to those who pay their dues, certain that members cannot in turn make keys to share with other, non-paying acquaintances! NOTE: Stamping “do not duplicate” on an ordinary key is not very effective! Some locksmiths will require ID or a note on letterhead to duplicate such a key. But anyone can produce letterhead, and there is no way to verify authorization to duplicate. There is simply no way to control duplication of a key that is available at every locksmith shop, home improvement store, and shoe repair shop in the world. If you need to put an end to unauthorized duplication of keys at your home or workplace, you need to contact a professional locksmith for restricted key products!
