Locker Keys UK: Replacement, Types, Codes and Ordering Guide (2026)

Locker keys are replacement keys made for specific locker locks in schools, workplaces, leisure facilities and industrial settings. In the UK, most replacement locker keys are cut to code using the number stamped on the original key or lock face.

To find the correct match by brand, browse our locker keys by manufacturer, including Ojmar, L&F and ASSA ranges.

What Are Locker Keys and How Do They Work?

Locker keys are made for specific locker lock mechanisms. In most cases, they are cut to code, meaning the shape of the key is determined by a unique reference number stamped on the lock or original key.

Unlike general household keys, locker keys are not interchangeable. Each key matches a specific lock series, so accurate code and manufacturer details matter when ordering a replacement. For organisations managing larger locker estates, using reliable replacement locker keys helps maintain access without replacing complete locks.

Common Locker Key Types and Systems Used in the UK

Different lockers use different key systems depending on the lock type, environment and security level required. If you need to match a specific key type or manufacturer range to an existing lock, see our locker keys by manufacturer page.

The right replacement depends on both the lock type and the key series, so identifying the system correctly helps avoid delays and ordering errors.

• Standard cam lock keys – common in schools, workplaces and general staff storage
• Mastered key systems – allow authorised management override access
• Coin return locker keys – used in leisure, visitor and changing room environments
• Wrist strap keys – suited to gyms, pools and other wet areas
• Restricted or higher-security locker keys – used where tighter control over access and duplication is required

Common ordering mistakes: The most frequent issues are misreading the key code, ordering from the wrong manufacturer range, or assuming keys are interchangeable across lockers. Always confirm the code and brand before ordering.

Each of these systems has its own replacement route, so identifying the correct key series or lock type is the first step. For facilities managing multiple lockers, combining master key access with clearly tracked replacement keys improves control and reduces downtime.

Locker Key Codes Explained

Most locker keys are identified using a key code. This is usually stamped on the original key or on the face of the lock.

If you need help locating the correct number, read our guide on how to find your locker key code. For a closer look at manufacturer ranges and numbering logic, see locker key numbers explained.

Common UK locker key ranges include:

• L&F (Lowe & Fletcher) locker key ranges
• ASSA locker key ranges
• Ojmar locker key ranges

The code determines the cutting pattern used to produce the replacement. Without it, ordering becomes less precise and may require lock identification instead.

How to Order Replacement Locker Keys

Ordering replacement locker keys is usually straightforward when the correct information is available.

• Locate the key code on the key or lock
• Identify the lock manufacturer if possible
• Confirm how many keys are required
• Choose the delivery speed that suits your site

When the code and manufacturer are correct, ordering is usually faster and more cost-effective than replacing the lock.

You can order directly through our locker key replacement service, where keys are cut to code and dispatched quickly across the UK.

What to Do If You Have Lost Your Locker Key

Losing a locker key is common, particularly in shared or high-use environments.

If the code is known, replacement is usually simple. If the code is not known, you may need to:

• Check the lock face for a stamped code
• Refer to locker records or key logs
• Identify the lock brand or series
• Replace the lock if identification is not possible

Planning ahead with a clear key management system reduces disruption when keys go missing. For the full step-by-step process, read Lost Locker Key? What to Do Next.

In many cases, ordering a replacement locker key cut to code is faster and less expensive than replacing the full lock.

If replacement is urgent, see our guide to next-day locker key replacement in the UK.

Cut to Code Keys: How the Process Works

Cut-to-code keys are produced from the original lock specification rather than copied from an existing key. This helps maintain consistency and accuracy across single lockers and larger locker systems.

You can read the full explanation in our guide to cut to code locker keys.

If you already have the code, go straight to our replacement locker keys cut to code service.

This method is especially useful for:

• Bulk replacement orders
• Facilities management teams
• Schools and workplaces
• Maintenance departments

Managing Locker Keys in Workplaces and Facilities

Good key management reduces loss, lowers replacement costs and improves security.

• Keep a clear record of key codes
• Keep a record of which user, locker or department each key is assigned to
• Use labelled or numbered identification systems
• Store spare and master keys securely
• Review access responsibility and issue procedures regularly

Locker systems, locks and keys should be planned together. You can explore compatible options across our locker locks and locker ranges.

For practical day-to-day control, read how to manage locker keys in the workplace and locker key services for facilities management teams. Many sites also use secure storage such as key cabinets to manage spare and master keys safely.

Where damaged locks are causing repeat key issues, compare compatible locker locks before replacing complete doors or full locker units.

Locker Key Accessories and Identification

Locker keys are often paired with accessories that make them easier to identify, issue, return and manage across larger sites.

For practical system control, read how to label and organise locker keys properly and browse our locker accessories.

• Key fobs and tags
• Numbering systems
• Wrist straps for wet areas
• Colour coding for departments or user groups

These accessories can reduce confusion, speed up identification and support better day-to-day key control.

Choosing the Right Locker Key Solution

The right solution depends on your environment, security needs and usage levels. Schools may prioritise simplicity and low replacement cost, while workplaces and managed facilities may need stronger control, spare key procedures and clearer tracking.

A simple way to choose the right route is to start with the information you already have.

• If you know the key code, order a cut-to-code replacement
• If you know the brand but not the code, identify the manufacturer first
• If the key is lost and the code is missing, inspect the lock face and site records
• If the lock cannot be identified, replacing the lock may be the better route
• If you manage a larger site, keep a code register and secure spare key system

Before replacing a lock, it is worth confirming whether a compatible locker key replacement is available, as this is often the simpler and lower-cost solution.

Frequently Asked Questions About Locker Keys

Can I replace a locker key without the original?

Yes, if you have the key code. Without it, you may need to identify the lock from the face of the lock, site records or manufacturer details. If none of that is possible, lock replacement may be necessary.

Where do I find the code on a locker key?

The code is usually stamped on the original key or on the face of the lock. If it is not visible, you may need to identify the lock brand or refer to site records.

How long does it take to get replacement locker keys?

Most cut-to-code locker keys can be dispatched quickly, and next-day UK delivery may be available depending on the order and key range.

Are all locker keys the same?

No. Locker keys vary by manufacturer, lock type and code series, which is why accurate identification matters when ordering replacements.

What is the best way to manage locker keys?

Maintain a clear record of codes, use labelled systems, control who receives keys and keep spare or master keys securely stored.
