Locker Lock Conversion

World of Books asked Total Locker Service to help resolve an operational problem with shared staff lockers in a multi-shift workplace. The existing key-lock system was no longer working well because lockers were being personalised by individual users and keys were being lost as staff changed.

The original request was to convert the lockers to coin-operated locks. After reviewing the existing metal lockers, this was not considered a practical retrofit, so alternative locking options were assessed instead.

The World of Books locker problem

The workplace operated across multiple shifts, with lockers intended to be used temporarily during a single shift rather than permanently assigned to one member of staff.

• staff were beginning to treat shared lockers as personal lockers;
• locker keys were being lost as employees changed;
• management needed a way to regain access to lockers left secured after a shift;
• the existing locker bodies were still serviceable, so full replacement was unnecessary;
• the chosen solution needed to support temporary shared use.

Locking options considered

We considered two practical alternatives to the existing keyed locks:

• a mechanical combination lock;
• the KL1000 electronic combination lock.

The electronic option was selected because it better matched the shift-based operating model. Users could secure a locker without needing a physical key, while management retained an override method for lockers that remained locked after the user had left.

Why the KL1000 was selected

The KL1000 provided a practical way to move the site from permanent keyed access towards temporary code-based use without replacing the locker bodies themselves.

• No user key needed for normal locker use.
• Management override access could be retained.
• Temporary users could use a personal code during their shift.
• Lockers left secured at the end of a shift could be reopened by authorised staff.
• The existing locker installation could be retained.

The locks were configured with management-level access so authorised staff could recover lockers that had been left locked. The exact programming and code hierarchy should always follow the current KL1000 product instructions and the site’s own access-control policy.

Lock retrofit and installation

Total Locker Service carried out the lock conversion on the existing lockers rather than supplying a completely new locker installation.

1. Existing lockers assessed. The locker doors and current lock arrangement were checked for retrofit suitability.
2. Replacement lock selected. The KL1000 was chosen to support temporary shared use.
3. Conversion work completed. Existing locks were removed and the replacement electronic locks fitted to the locker doors.
4. Management access configured. The locks were programmed for authorised override access.
5. Operation checked. The converted lockers were tested before completion.

This type of project depends on physical lock compatibility. Door thickness, existing cut-outs, fixing positions and lock footprint should all be checked before a retrofit is approved.

For the wider compatibility process, see our Locker Lock Replacement Guide UK and Retrofit Locker Locks UK.

From keyed lockers to shared shift use

The main objective was not simply to replace one lock with another. The project was intended to change how the lockers were used.

Before conversion	After conversion
Users depended on physical keys	Users could operate lockers with a code
Lost keys created administration problems	Normal use no longer depended on issuing keys
Shared lockers were being treated as permanently assigned	The locking system better supported temporary shift use
Management access depended on the existing key arrangement	Authorised override access was retained
Existing locker bodies were at risk of unnecessary replacement	Serviceable lockers were retained and upgraded

Operational benefits for World of Books

The conversion allowed the existing lockers to be managed more effectively as shared shift lockers rather than permanent keyed lockers.

• fewer problems caused by lost user keys;
• better support for temporary locker use;
• management access to lockers left secured after a shift;
• continued use of the existing locker bodies;
• potential to reduce unnecessary locker allocation where one locker could serve different users across separate shifts;
• more flexibility in how changing-room space was used.

The project also demonstrates that operational locker problems do not always require complete locker replacement. Where the structure is still serviceable, changing the lock and operating method can sometimes solve the underlying issue more efficiently.

When electronic combination locks suit shift work

Electronic combination locks can be useful where a workplace needs lockers to be reused by different people at different times and does not want to issue a physical key to every user.

• multi-shift workplaces;
• temporary staff storage;
• shared changing rooms;
• sites with frequent staff turnover;
• facilities where management needs controlled override access.

The access technology should still be matched to the operating model. For a wider comparison of key, combination, coin, RFID and digital systems, use our Locker Access Control Systems UK guide.

Locker management and shared use

Changing the lock is only one part of a shared-locker system. The organisation also needs clear rules covering how long a locker may be used, what happens when it is left occupied and who is authorised to override or reset a lock.

This case study therefore sits between lock retrofit and locker management: the hardware change enabled a different operating model, while the site’s procedures determined how that model worked in practice.

World of Books Locker Lock Conversion FAQs

Why were the World of Books locker locks changed?

The existing keyed system was creating operational problems in a multi-shift workplace because keys were being lost and shared lockers were being treated as permanently assigned.

Why were coin locks not fitted?

Coin locks were initially considered, but the existing locker configuration was not suitable for the proposed retrofit, so alternative combination-lock options were reviewed.

Why was the KL1000 chosen?

The KL1000 better supported temporary shared use because staff did not need individual locker keys and authorised management access could still be retained.

Can existing lockers be converted to electronic combination locks?

Sometimes. The locker door, lock cut-out, fixing points, door thickness and replacement-lock footprint all need to be checked before a retrofit is approved.

Are electronic combination locks useful for shift workers?

They can be useful where lockers are shared between different users across separate shifts and the organisation wants to avoid issuing a physical key to every user.

Summary: World of Books KL1000 locker conversion

The World of Books project began as a request to replace keyed locker locks with coin locks, but the existing locker configuration made that approach unsuitable.

By reviewing the actual shift-based operating problem, Total Locker Service recommended and installed KL1000 electronic combination locks instead. The conversion retained the existing locker bodies, reduced dependence on physical keys and created a locking system better suited to temporary shared use.
