Master key suites
See how one master key suite can give guests or occupiers, staff, cleaners, handymen, managers and authorised owners different levels of access across offices, hotels, holiday lets and similar managed premises.
Guest key: access to Rooms / offices.
Illustrative example only: a real master key suite is designed around your premises, doors and authorised users.
Locks keyed alike
Choose an example setup to see how compatible locks can be keyed alike so the same key operates your front, back and side doors, garage and outbuilding.
Main doors: one key can operate Front door, Back door.
Illustrative example only: keyed alike compatibility depends on the selected lock or cylinder types. Additional keys can be supplied for the same keyed alike suite.
R Locksmiths LTD planning tool
Plan doors, cylinders, key quantities and access groups for an office, hotel, holiday let or other managed premises. This is a planning proposal, not a final manufacturer keying schedule. R Locksmiths LTD can review the plan and confirm the final specification if you request a quote.
Master Key System Planner 2
Plan your master key system, start by filling out your project details.
Add each door or lock location once, then add one or more lock specifications underneath it. Use Quantity for identical locks with the same format, finish and size; add another lock specification when the format, finish, size or fitting details differ. The planner shows only the sizing fields that apply to each selected format. Final dimensions and compatibility must be confirmed before a final specification is agreed.
Add each location once. Door / area is required and is used by the diagram and access/location totals. Add multiple lock specifications inside a location when one door or opening has different locks or different sizes.
For larger sites, Building, Floor / zone and Department / area are optional ways to organise locations. New locations reuse the previous row's grouping so you can add several doors quickly, and you can change any value at any time.
For a Master Key proposal, access is assigned to the door / lock location. All keyed locks listed under that location therefore share the proposed access assignments. Add a separate location only when the opening needs different access permissions.
Use Manage keys and access beside a lock to assign access groups. Quantity-based locks can share one access setup or, when permitted, be configured individually.

This expanded view splits larger systems into readable colour coded diagrams while retaining every configured access group and lock location.

Keys and access groups
Select the access groups that may operate this lock. Access groups and their key quantities remain shared across the project.
A new group is added to the project group collection and is immediately available throughout the planner.
Project access
Create and edit shared access groups. Changes use the same project relationships as the lock controls and project review.
The Access matrix needs at least one Door / area and one access group.
Tick: all locks in this quantity.
Dash: some locks in this quantity.
Empty: no locks in this quantity.
Use familiar role names. R Locksmiths LTD can translate the proposal into the final change key, sub master, master or grand master architecture and confirm the final system design if you send an enquiry.
Measure from the centre fixing screw to each end and enter the outside side first. This is especially important when an anti snap cylinder has an external sacrificial section. The planning range is 20 to 120 mm per measured side in 0.5 mm increments. For many keyed cylinder systems, the keyed side range starts at 35 mm. A keyed side of 30 mm or below may not be compatible with the same system as 35 mm or larger sizes. Alternative arrangements may sometimes be possible, so contact us to discuss. If your measured size falls outside the planning range, add it to Notes for quote review.

5 keys are included as standard. Request only any extra copies you need. One keyed alike key operates all locks in the keyed alike set, so the key quantity is not multiplied by the number of locks.
One keyed alike key operates all locks in this keyed alike set. Extra keys are additional copies of that same key and are not multiplied by the number of locks.
5 standard keys + 0 extra keys = 5 keys total
