Re-keys are one of the most effective ways of guaranteeing the ongoing security of your property. Virtually any lock can be refitted, and having it done brings many secondary benefits beyond what motivates most people to get one. Any time your keys are lost, a new person moves into your property, there is a burglary, or it has simply been awhile since you changed your locks, it is a good idea to have the service performed. If you are considering a having the locks changed for one entry point and have a large number of other locks, you may even consider having the service performed on several of them to create a master key system, which may allow you to retire much of your keyring.
