Locker Keys UK: Replacement & Key Cutting Guide (2026)

If you need replacement locker keys in the UK, the process depends on the lock manufacturer, key number and lock type. Whether you have lost a locker key, need a spare, or manage multiple lockers across a site, understanding the correct identification process prevents costly mistakes.

This guide explains how locker key replacement works, how to identify your key code, and how to order correctly in 2026.

How to Identify Your Locker Key

Most locker keys are cut to a specific code stamped on the key head or engraved near the lock barrel.

• Check the key head for stamped numbers
• Look at the lock face for engraved codes
• Identify the manufacturer logo
• Confirm whether it is a cam lock, coin lock or digital override key

Replacement Locker Keys by Manufacturer

Replacement keys must match the original lock manufacturer and series. Common UK locker lock brands include:

• Ojmar
• Lowe & Fletcher (L&F)
• Ronis
• Eurolocks
• Probe
• Helmsman

Lost Locker Key: What To Do

If a locker key is lost, you have three options:

• Order a replacement key using the stamped code
• Use a master key (site managers)
• Replace the lock if the code cannot be identified

Key Cutting by Code

Locker key cutting by code allows replacement without the original key. This requires:

• Correct manufacturer identification
• Clear key number
• Lock type confirmation

Bulk Replacement Keys for Sites

Schools, gyms and workplaces often require bulk key replacement. Keeping a master list of key codes simplifies future orders.

When Should You Replace the Entire Lock?

If the key code is unreadable, the lock damaged, or security compromised, replacing the entire locker lock may be more cost-effective than ordering keys.
