Replacement Locker Keys Cut to Code UK: Order Locker Keys by Number

You can replace most locker keys in the UK using the key number without removing the lock. Locker keys cut to code are the fastest and most cost-effective way to restore access when a key is lost, damaged or missing.

This guide explains how replacement locker keys work, how to find your key number, when you can order keys instead of replacing the lock, and what to do if the key number is missing or unknown.

Quick answer: If your locker key has a number stamped on it (or on the lock), you can usually order a replacement key cut to that code. If the number is missing or the key may have been stolen, replacing the lock may be safer.

What are locker keys cut to code?

Locker keys cut to code are replacement keys made using a unique key number. This number identifies the lock pattern, allowing a new key to be produced without needing the original key.

This is the standard method used across schools, workplaces, leisure centres and facilities management sites in the UK.

How to find your locker key number

The key number is essential for ordering a replacement. It is usually a short code made up of numbers or letters.

• Stamped on the original key
• Engraved on the lock face

• Provided in original locker documentation

If you cannot find the number, do not guess. Ordering the wrong key wastes time and cost.

Replacement locker keys for different environments

Schools

High loss rates make replacement keys essential. Schools should maintain a key register and keep spare keys controlled.

Workplaces

Replacement keys support staff lockers and reduce downtime. Keys should be issued and recovered during onboarding and offboarding.

Leisure centres

Replacement demand is high due to turnover. Consider coin or combination locks if loss is frequent.

Healthcare and NHS

Security is critical. Replace locks rather than keys if there is any risk of unauthorised access.

How to reduce replacement key demand

• Use key registers and tracking
• Issue keys with clear responsibility
• Keep spare keys secure
