Master Key System
A master key system involves several individual keys for individual doors, a master key to open all doors, and even sub-master levels. These systems are used for facilities where tenants only need access to specific areas. These systems rely on mechanical locks and physical keys and may sometimes be compromised with one missing key. And necessitates a locksmith changing the locks.
However, recent advances to the older “key” systems have given birth to the computerized master key system which provide easy admittance and restriction while eliminating the need for multiple physical keys per person.
With a computerized master key system, computer software is used to keep track of all the keys used in the system. Keys are code stamped with an ID label and this makes it possible to keep accurate records of keys. This allows addition, deletion or changes to the master key system.
Electronic Access Control Systems (Keyless Access Control)
Property managers are increasingly turning to electronic or computerized access control systems to manage ingress and egress into their properties. These involve ID cards or codes that are electronically linked to individuals. These can be programmed to allow or restrict access to specific individuals at specific times.
