Lock system design

What does lock system design involve?

Lock system design considers the property’s doors and key access as a whole, rather than choosing each lock independently. The aim is to give users access to the spaces they need while keeping key management clear.

Planning establishes which doors need separate keys, where one key can open several doors and what access each user group requires. We also assess whether existing locks can be retained or need updating.

When should you review the whole locking system?

A review can be useful during renovation, a change in how premises are used or a wider lock replacement project. It may also help when many keys have accumulated and it is no longer clear which doors they open.

Typical situations include:

• Updating locks for flats and shared areas in a housing company.
• Moving a business into new premises or changing the use of existing spaces.
• Giving different user groups access to different areas.
• Simplifying the use of several separate keys.
• Planning a phased update of existing locks.

Doors, users and key access

Planning starts with identifying the doors and the people who use them. We discuss who needs access to areas such as flats, storage rooms, offices and technical spaces.

Within the agreed scope, we can prepare a summary showing which keys open which doors. Key handover, returns and future changes are also considered. Access permissions are based on the requirements defined by the customer.

Existing locks and system compatibility

Replacing every lock may not be necessary. We assess whether existing hardware can be retained, rekeyed or supplemented with compatible components.

The options depend on the locks’ condition, construction, key system and parts availability. Locks from different systems cannot automatically be made to work with the same key. We explain any limitations before agreeing on implementation.

• Lock rekeying

Mechanical keys or electronic access control?

A mechanical key system may suit a property where users and access requirements remain relatively stable. If permissions change frequently or electrical access control is needed, it may be worth considering electric locks or an electronic access control system.

Electronic functions, connections and any need for separate design work are assessed for the property. Implementing access control systems is not included in lock system planning.

• Electric lock installation

From planning to installation

We review the proposed arrangement, required changes and any suitable phasing. Before work is commissioned, we agree what the design service includes and how the decisions will be documented.

Lock and key supply, rekeying, installation and subsequent maintenance are agreed separately. This makes the scope and responsibilities clear before implementation.

How much does lock system design cost?

The cost depends on the property’s size, number of doors and user groups, the work needed to assess existing locks and the scope of planning. Any site visit and agreed documentation also affect the workload.

When contacting us, describe the property, its location, the approximate number of doors and what you want to change. We agree the design scope and price before starting. Equipment and installation are itemised according to the agreed supply and work.

How lock system planning works

1. Assess the property and requirementsWe review the doors, user groups, existing locks and the changes you want to make.
2. Plan the locks and access permissionsWe assess compatibility and agree which keys or credentials should open each door within the selected solution.
3. Agree on implementationWe review the proposal, documentation and any phased approach. Equipment supply and installation are agreed separately.
