How to Identify Your Locker Lock Type Before Ordering Parts

Identifying the correct locker lock type is one of the most important steps before ordering replacement parts, spare keys or new locker locks. Many locker locks look similar from the outside, but differ in footprint, fixing style, cam position, key series, operation mode and compatibility. Ordering the wrong parts can lead to wasted costs, delays and lockers that no longer secure properly.

This guide explains how to identify locker lock types used in UK schools, workplaces, gyms, leisure centres, warehouses and changing rooms. It covers keyed locker locks, combination locks, coin-operated locks, electronic locker locks, padlock fittings and the main features to check before ordering replacement parts or spare keys.

Quick answer: To identify a locker lock, check how it operates, look for a key number or manufacturer mark, inspect the lock shape and fixing method, then confirm the cam type, lock footprint and locker door preparation before ordering parts.

For broader guidance, see our Locker Locks UK master hub, read our Locker Lock Parts and Spares UK guide or explore our locker lock range.

Why identifying the correct locker lock matters

Locker locks are not universal. Two locks may appear similar but use completely different fixing systems, key profiles or cams.

Ordering the wrong replacement parts can cause:

• Locks that do not fit the door
• Incorrect cam operation
• Doors that fail to secure properly
• Master key incompatibility
• Wasted maintenance costs
• Locker downtime

Correct identification helps ensure replacement parts work properly the first time.

Main locker lock types

Locker Lock Type	How It Operates	Common Environment
Keyed cam lock	Uses a physical key	Schools and workplaces
Combination lock	Uses a code or dial	Schools and shared lockers
Coin-operated lock	Uses coin or token activation	Gyms and leisure centres
Electronic locker lock	Uses PIN, RFID or digital access	Modern workplaces and gyms
Padlock fitting	Uses separate padlock	Industrial and budget lockers

Step 1: Identify how the locker lock operates

The easiest starting point is checking how the lock is opened.

• Physical key? → Keyed locker lock.
• Dial or code wheels? → Mechanical combination lock.
• PIN keypad or RFID reader? → Electronic locker lock.
• Coin slot or token? → Coin-operated locker lock.
• Padlock loop or hasp? → Padlock fitting.

This immediately narrows down the spare parts and replacement options.

Step 2: Check for key numbers or manufacturer markings

Many locker locks include identifying numbers or manufacturer markings.

These may appear on:

• The key head
• The lock face
• The barrel
• The rear of the lock
• The locker manufacturer label

Common information may include:

• Key numbers
• Lock series numbers
• Brand names
• Master key references
• Part numbers

This information is extremely important when ordering:

• Replacement locker keys
• Replacement barrels
• Master keys
• Matching spare parts

See our Replacement Locker Keys Cut to Code UK guide.

Step 3: Inspect the lock footprint and door preparation

The lock footprint is the shape and size of the area where the lock fits through the locker door.

Check:

• Hole size
• Round or square cut-out
• Flush or recessed fitting
• Door thickness
• Fixing nut or screw positions
• Lock face dimensions

Even small differences can stop replacement locks fitting correctly.

This is especially important when upgrading from keyed locks to combination or electronic systems.

Step 4: Check the cam type and locking direction

The cam is the metal arm on the rear of the lock that secures the locker door.

Locker cams vary by:

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

Incorrect cams may cause:

• Doors failing to close
• Poor locking engagement
• Locks jamming
• Loose doors

Always confirm whether the locker door is left-hand or right-hand hinged before ordering replacement cams or locks.

How to identify keyed locker locks

Keyed locker locks are one of the most common locker systems in schools, workplaces and changing rooms.

Main identifying features include:

• Physical key access
• Cam on rear of lock
• Key number stamped on key or barrel
• Threaded barrel with fixing nut
• Master key compatibility in many systems

Read our Keyed Locker Locks UK guide.

How to identify combination locker locks

Combination locker locks use mechanical dials or code wheels instead of physical keys.

Common identifying features include:

• Rotating dial or number wheels
• No physical key for normal use
• Master override access on many models
• Public-use or private-use modes
• Larger lock body than basic cam locks

See our Locker Combination Locks UK guide.

How to identify coin-operated locker locks

Coin-operated locker locks are commonly used in gyms and leisure centres.

Main identifying features include:

• Coin slot or token slot
• Coin return or coin retain operation
• Public-use locker mode
• Master key override
• Larger front plate assembly

Read our Coin-Operated Locker Locks UK guide.

How to identify electronic locker locks

Electronic locker locks use digital access systems rather than mechanical keys.

Main identifying features include:

• PIN keypad
• RFID reader
• Card or fob access
• Battery compartment
• Digital display or indicator lights
• Emergency override access

Electronic systems are increasingly used in hybrid workplaces and premium leisure facilities.

Read our Electronic Locker Locks UK guide.

How to identify padlock fittings

Padlock fittings are easy to identify because the locker itself does not contain a full built-in lock.

Main identifying features include:

• Hasp or staple fitting
• Padlock loop
• No internal lock barrel
• External user-supplied padlock
• Simple door reinforcement plate

See our Padlock Fittings for Lockers UK guide.

Common mistakes when identifying locker locks

• Assuming all cam locks are identical
• Ignoring cam length and offset
• Confusing locker number with key number
• Ordering without checking door thickness
• Ignoring master key compatibility
• Mixing incompatible lock brands
• Ordering electronic upgrades without checking the cut-out size

Always check measurements and compatibility before ordering large quantities of parts.

Best identification approach by environment

Environment	Most Important Identification Check
Schools	Key number and master key compatibility
Workplaces	Cam type and lock footprint
Gyms	Coin system or electronic compatibility
Swimming pools	Corrosion resistance and lock type
Factories	Heavy-duty lock and cam style
Hybrid offices	Electronic system compatibility
