The best way to keep your house secured from break-ins is to install different locks on every door and window.
While doing so is not difficult, it is simply not practical to carry around a chain of keys as big as janitors’.
The right locksmith, though, can help you with this problem.
The solution to this dilemma is to employ a highly trained locksmith to re-key every lock in the house to fit the same, single key.
This service is much easier and more cost effective than most people imagine; it is called Master Key System.
