A master key plan is the essence of modern mechanical access control. It is recommended for all types of building, from residential houses and apartment blocks through to medium-sized or large organisations with a hundred keys or more. This becomes particularly important in the following cases:
- Keeping control of who holds which key to which room for security reasons.
- To eliminate the need to carry too many keys, i.e. convenience.
- For safety reasons, e.g. when emergency services need quick, round-the-clock access to all rooms without having to search for the right key, e.g. in nursing homes, old people’s homes or in student accommodations.
