Locker Lock Parts and Spares UK: Cam Locks, Barrels, Keys and More

Locker lock parts and spares help extend the life of lockers without replacing the entire unit. Many locker problems can be solved by replacing individual parts such as lock barrels, cams, keys, retaining clips, fixing nuts or padlock fittings rather than changing the whole locker or full lock assembly.

This guide explains the main locker lock parts and spare components used in UK schools, workplaces, gyms, leisure centres, warehouses and changing rooms. It covers locker cam locks, replacement barrels, locker keys, master keys, lock cams, electronic lock spares, padlock fittings and common replacement issues.

Quick answer: The most commonly replaced locker lock parts are keys, lock barrels, cams, fixing nuts, retaining clips and padlock fittings. Replacing these components can often restore locker security without replacing the entire locker.

What are locker lock parts and spares?

Locker lock parts and spares are replacement components used to repair, maintain or upgrade locker locking systems.

Instead of replacing an entire locker or full lock assembly, many faults can be repaired by replacing one damaged or worn component.

This helps reduce:

• Maintenance costs
• Locker downtime
• Waste during refurbishment
• Operational disruption
• Full lock replacement costs

Main locker lock parts and spare components

Locker Lock Part	Main Purpose	Common Replacement Reason
Locker keys	Operate keyed locks	Lost or broken keys
Lock barrels	Main locking mechanism	Wear or damaged cylinders
Lock cams	Secures the door	Bent or worn cams
Fixing nuts	Secures lock to door	Loose or stripped fixings
Retaining clips	Holds lock assembly in place	Missing or damaged clips
Padlock fittings	Supports padlock use	Damaged hasps or staples
Master keys	Emergency or management access	Lost or expanded access needs
Electronic lock parts	Supports digital locks	Battery or keypad failure

Locker keys and replacement keys

Replacement locker keys are one of the most commonly requested locker spare parts.

Many locker locks use numbered keys that can be cut to code without replacing the full lock.

Replacement keys are commonly needed because of:

• Lost keys
• Broken keys
• Staff turnover
• Student locker reassignment
• Additional authorised users

Before ordering replacement keys, check:

• Key number
• Lock series
• Locker manufacturer
• Whether a master key system exists

See our replacement locker keys service and How to Stop Lost Locker Keys.

Locker lock barrels and cylinders

The lock barrel or cylinder is the core mechanism inside a keyed locker lock.

Barrels may need replacement when:

• Keys stop turning smoothly
• The lock becomes stiff
• The cylinder is vandalised
• The lock is re-keyed
• Security is compromised

Some locker systems allow barrel-only replacement while keeping the same outer lock housing.

This can reduce replacement costs significantly during large refurbishments.

Locker lock cams

The cam is the metal arm attached to the back of the lock that secures the locker door behind the frame.

Cams vary by:

• Length
• Offset
• Bend angle
• Rotation direction
• Fixing style

Locker cams may need replacing if they become:

• Bent
• Worn
• Loose
• Broken after forced entry
• Incorrect for a replacement lock

A lock may still function mechanically but fail to secure the door properly if the cam is damaged or incorrectly sized.

Fixing nuts, washers and retaining clips

Small fixing components are often overlooked but are essential for keeping locker locks secure and aligned.

These parts may include:

• Fixing nuts
• Star washers
• Retaining clips
• Threaded collars
• Mounting screws

Common problems include:

• Locks spinning inside doors
• Loose lock bodies
• Door misalignment
• Missing clips after maintenance

Replacing these small parts can often restore a locker lock without needing a full replacement.

Padlock fittings and locker hasps

Padlock fittings allow lockers to use separate user-supplied padlocks rather than built-in locking systems.

Common spare parts include:

• Hasp plates
• Staples
• Padlock eyes
• Fixing brackets
• Door reinforcement plates

Padlock fittings may need replacement after:

• Forced entry
• Corrosion
• Oversized padlock damage
• Wear from heavy daily use

See our Padlock Fittings for Lockers UK guide.

Master keys and management keys

Many locker systems use master keys that allow authorised staff to open multiple lockers for maintenance or emergency access.

Master key systems are commonly used in:

• Schools
• Workplaces
• Leisure centres
• Healthcare facilities
• Universities

Important considerations include:

• Who holds master keys
• Key tracking procedures
• Replacement master key security
• Whether locks are keyed alike or differently

Lost master keys may require full lock replacement if security is compromised.

Electronic locker lock spare parts

Electronic locker locks use different spare components from traditional keyed systems.

Common electronic lock spares include:

• Battery packs
• Battery covers
• RFID readers
• Keypads
• Emergency override keys
• Wiring components
• Control modules

Electronic systems may need maintenance because of:

• Battery failure
• Water ingress
• Heavy public use
• Impact damage
• Software or firmware issues

Read our Electronic Locker Locks UK guide.

When should locker parts be replaced instead of the whole lock?

Replacing individual locker parts is usually worthwhile when:

• The lock housing still works properly
• Only one component is damaged
• Large numbers of lockers require maintenance
• Replacement parts are readily available
• The lockers are still structurally sound

Full lock replacement may be better when:

• The mechanism is heavily worn
• Security has been compromised
• The site is upgrading to a new lock system
• Spare parts are obsolete
• The lock repeatedly fails

See our Locker Lock Replacement Guide UK.

Common locker lock spare issues

• Ordering the wrong cam length
• Using the wrong key series
• Incorrect lock rotation direction
• Mixing incompatible lock brands
• Missing retaining clips after maintenance
• Oversized padlocks damaging fittings
• Replacing barrels without checking master key compatibility

Always confirm compatibility before ordering large quantities of locker spares.

Can I get replacement locker keys cut to code?

Yes. Many locker keys can be cut to code if the key number or lock series is known.

What is a locker lock barrel?

The barrel or cylinder is the internal mechanism that operates the keyed locker lock.

Can locker cams be replaced separately?

Yes. Many locker lock cams can be replaced individually if the lock body is still working correctly.

Do electronic locker locks have spare parts?

Yes. Electronic locker locks commonly use replacement batteries, RFID readers, keypads and override components.

When should a full locker lock be replaced instead of a spare part?

Full replacement is usually better when the lock mechanism is heavily worn, obsolete or repeatedly failing.

Are locker lock parts universal?

No. Locker lock parts vary by manufacturer, lock series, cam type, fixing method and locker door preparation.
