A Master
Key System allows you to have one key to open all locks,
with other levels of keys having the ability to open
certain pre-determined areas. This can eliminate the
need to carry all those keys with you and limits the
areas to which other persons have access. Whether you
need to control a domestic building such as your home,
or a large scale commercial or industrial complex, having
total control of access to all entry points through
a Master Key system makes a lot of sense.
A Restricted
Key System has the same potential as the Master Key
System with the added advantage of complete control
over the entire lock and key system; i.e. no work can
be legally performed on your system unless you authorise
it. Also, the only locksmith that can work on your system
is the locksmith with whom the system is held
