Tiered Access Solutions for Every Property

A master key system is a sophisticated locking hierarchy, where a single “Master Key” opens all doors, while individual “Servant Keys” remain restricted to specific rooms or zones. Furthermore, this setup is indispensable for Oxfordshire’s diverse commercial and residential sectors, ranging from large-scale HMOs in Oxford to professional business parks and schools across the county. In addition, we provide expert engineering to ensure your system is intuitive, scalable, and impossible to duplicate without authorisation.

Professional Access Management

We only use high-quality British Standard cylinders and registered key profiles to ensure your system provides both convenience and elite protection. Our mobile workshop is equipped to handle the maintenance and expansion of your suite as your business or portfolio grows.

Grand Master Key Suites

The ultimate in control—a single key that provides overarching access to every lock across an entire site or multiple geographic locations.

Landlord & HMO Solutions

Allow tenants to access communal areas and their own rooms with one key, while you retain a master key for all units—ideal for ensuring privacy and safety.

Restricted Key Profiles

Prevent unauthorised key copying with patented cylinders. New keys can only be cut by AJK Locks upon verification from the authorised system owner.

Commercial Maintenance

Comprehensive support for existing master key systems, including lock repairs, key replacements, and the addition of new doors to your existing suite.
