Why Choose a Master Key System in Residential Situations?
If you find that you are carrying around a large bunch of keys with you everywhere you go, then why not consult a domestic locksmith about the possibility of installing a master key system for you in your home? Essentially, master key systems provide you with a single key that will open all of the appropriate locks in your home while still only allowing limited access to other key holders. They are in widespread use in industrial settings as well as places with large numbers of rooms, such as hotels, for example.
