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

Locker keys are a small part of a storage system, but they carry significant operational importance. In schools, workplaces, leisure facilities and industrial environments, a missing or incorrect key can disrupt access, delay users and create security concerns. A clear, well-managed locker key system keeps storage reliable, secure and easy to maintain.

This guide explains everything you need to know about locker keys in the UK, including how replacement keys work, how to identify key codes, the different types available and how to order correctly. It also links through to the relevant services so you can move from understanding to action quickly.

What Are Locker Keys and How Do They Work?

Locker keys are cut to match a specific lock mechanism. 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 corresponds to a defined lock series, which means accuracy is critical when ordering replacements.

If you are unsure how locker systems are structured overall, it helps to review the broader locker guide before selecting keys.

Types of Locker Keys Used in the UK

Different lockers use different key systems depending on the lock type, environment and security level required.

• Standard cam lock keys – the most common option for schools and workplaces
• Mastered key systems – allow management override access
• Coin return locker keys – used in leisure and changing room environments
• Wrist strap keys – designed for gyms and wet areas
• High-security keys – used where controlled access is critical

Each of these systems requires a different replacement approach, so identifying the correct type is the first step.

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, see locker key numbers explained.

Common UK locker key systems include:

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

The code determines the exact cutting pattern. Without it, producing an accurate replacement becomes more difficult and may require lock identification instead.

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 simple. If not, you may need to:

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

Planning ahead with a clear key management system reduces disruption when keys go missing.

Cut to Code Keys: How the Process Works
