How master key systems work

A master key system allows one key to open multiple locks, while individual keys only provide access to specific doors. This helps control movement across different areas of a property, making it ideal for landlords, offices, shops, schools, and shared buildings. It simplifies access while maintaining security and organisation. As part of setting up or maintaining the system, we can also carry out lock upgrades to ensure your locks meet current security standards and work efficiently within the system.
