Lock Sales and Key Cutting FAQs

A change key normally opens one designated lock or group, while a master key is authorised to open several locks within the planned hierarchy. This lets everyday users access only the areas they need, while designated managers hold broader access without carrying a separate key for every door.
Start by mapping doors, rooms, user roles and any areas that must remain restricted. Consider staff changes, cleaning, maintenance, emergencies and future expansion. The system can then be designed around real responsibilities, avoiding a hierarchy that is either too restrictive for daily work or unnecessarily broad.
Because a master key may open several areas, it should be treated as a significant security event. Record who held it, identify its access level and review the likely exposure promptly. The appropriate response depends on the system design and risk, and may involve changes to affected cylinders or access arrangements.
Yes. A hierarchical suite can be planned so departmental keys open their own allocated areas, individual keys open fewer doors and higher-level keys provide wider authorised access. The exact structure should remain understandable and manageable; excessive complexity can make issuing, auditing and replacing keys more difficult.
A register records each key number, access level, holder, issue date and return. This makes missing keys easier to identify and helps prevent uncontrolled circulation. Organisations should also have a clear procedure for authorisation, secure storage of spares, leavers and periodic checks of keys in use.
Expansion may be possible if future doors and access groups were considered during the original design. Available combinations and product compatibility can place limits on an existing suite. Discussing likely growth at the planning stage can reduce disruption and avoid having to redesign the hierarchy sooner than expected.
