A locksmith can be categorized according to their ability or field of specialization. A mobile locksmith works out of an automobile, whereas commercial locksmith is the one who is employed by a particular institution. When seeking the service of a locksmith it is better to get service from a specialized and experienced 24 hour locksmith. A specialized locksmith usually offers many services like working on advance security locks, the repair and installation of intercom systems, fitting of locks on iron gates, lock changes, lock rekeying or master re-keying and fitting and repairs of panic bars and other accessories like peepholes.
These days, locksmiths also carry out duties far from the conventional installation of locks. They even take on the service of access control systems and alarm systems for both commercial and residential needs. The service of a locksmith starts from the fitting of a file cabinet lock and extends right up to the fitting of Closed Circuit Television (CCTV). When discussing their services, emergency and automobile locksmith services are also to be considered.
