Locksmiths are not the only ones that have key machines. Hardware stores apartment complexes that have maintenance departments and large industrial operations also have key duplicating machines. In order to maintain proper operation they must be serviced at regular intervals. The key machine servicing can include things such as adjusting the key guide to cut keys accurately or lubricating the bearings in the engine and in the cutter head. The key vices that are located on the carriage must also be inspected cleaned and lubricated for proper operation. Each of these tasks should be completed by a well trained
certified registered locksmith to insure good results.
