This practice is probably the most common job performed by locksmiths who specialise in domestic and commercial applications.
You would normally call a locksmith in a domestic situation or residential when moving into a new home or flat after a recent purchase. I remember when I was a kid, that we always use to call a locksmith when relocating to a new home. Little did I really know at the time, what it was all about.
Keys can be duplicated at any key cutting shop, hardware shop, locksmith shop or any business which offers key duplicating services. By the way not all keys can be duplicated or copied without the proper written authority. Some keys are restricted to only be passed on to a person who has an authority to copy and receive the key. When keys are of a non-restricted nature, it allows anybody with a key to get another key copied.
This copying of keys with non-restricted systems can lower the security of a new home or flat or on any lock which gives access to those premises. Nobody really knows how many keys have been copied over the years for that lock to that recently moved in property. A fully licensed locksmith will be able to fix this problem very fast by pulling out the old barrel to that lock cylinder and repining it with a new code to fit a new key.
The cost of this job can vary and it should be cheaper to use a local locksmith from your area during normal business hours. Some companies do this service for as low as $95 during normal business hours plus the cost of the key ( normally $4 – $5 per cut key ). This would be for a standard inline cylinder type lock and include 1 lock recode and should include also the service call out fee with work included. Additional locks to rekey should not cost more than 30% of the first lock, plus the cost for the amount of keys required.
