Locker Key Cutting vs Key Duplication: What’s the Difference? (UK Guide 2026)

When replacing locker keys in the UK, many people use the terms “key cutting” and “key duplication” interchangeably. However, the two processes are different, particularly for locker locks used in schools, gyms and workplaces.

This guide explains the difference and helps you choose the correct method for replacing locker keys.

What Is Locker Key Duplication?

Key duplication involves copying an existing physical key. A working original is required, and the duplicate is cut to match the original’s profile.

• Requires original key
• Suitable for simple mechanical locks
• Often used for domestic keys

What Is Locker Key Cutting by Code?

Locker key cutting by code does not require the original key. Instead, the replacement key is cut using the manufacturer’s key code reference.

• No original key required
• Based on stamped key code
• Manufacturer-specific process
• Common in commercial locker systems

Which Method Is Used for Locker Keys?

Most commercial locker keys are cut by code rather than duplicated. This ensures the replacement matches the original lock specification exactly.

Why Code Cutting Is Safer for Facilities

• Maintains manufacturer accuracy
• Supports master key systems
• Reduces compatibility errors
• Prevents miscut duplicates

When Duplication May Not Be Suitable

• Key is worn or damaged
• Security risk requires verification
• Lock is part of a controlled key system
• Original key unavailable

When to Replace the Entire Lock Instead

If no code is available and the original key is missing, replacing the locker lock may be more practical. View our range of Locker Locks for compatible options.

Common Misunderstandings

• Assuming all locker keys can be duplicated locally
• Confusing locker number with key code
• Using worn keys for duplication
• Ordering without confirming manufacturer
