What Are Locker Cam Locks?

Locker cam locks are compact, key-operated locks that secure a locker door by rotating a metal cam behind the door frame. They are widely used on metal and laminate lockers in schools, workplaces, leisure centres and changing rooms.

Total Locker Service supplies replacement cam locks for lockers, including universal and manufacturer-specific options. Our range covers Lowe & Fletcher, Probe, Pure, ASSA and Ojmar locks for compatible existing installations.

Replacing a cam lock is often more economical than replacing a complete locker door. The correct replacement depends on the lock body, fixing arrangement, cam dimensions and key series rather than the locker brand alone.

We also assist with identifying locks used by other manufacturers, including Ronis, Link51 and Helmsman. Customers replacing existing locks can supply photographs, key numbers and measurements to help establish compatibility.

Mechanical key operation: no batteries or electronic access system required.
Manufacturer-specific replacements: select by lock type, key series and fitting.

If the existing lock still works and only a key is missing, visit our replacement locker keys section before purchasing a new mechanism. For other locking methods, browse our locker locks.

Important: use the individual product pages to confirm current prices, available configurations and lead times. Similar-looking cam locks may have different keying systems or mounting hardware.

Universal 31/33 vs Probe 36/38 Cam Locks

The Universal 31/33 and Probe 36/38 cam locks are manufactured by Lowe & Fletcher. They use the same underlying mechanical lock design, with different key bitting and associated key series.

When replacing locks in an existing installation, especially one using a master-key arrangement, identifying the original key series is important. A replacement from a different series should not be assumed to operate with existing keys.

Also check the fixing arrangement supplied with the selected product. A mechanically similar lock may be supplied with different retaining hardware or cam options.

Compare the Lowe & Fletcher 31/33 Universal Cam Lock with the 36/38 Probe Cam Lock before ordering.

How to Identify the Correct Replacement Cam Lock

A replacement locker cam lock must fit the existing door and operate correctly against its locking frame. Check the following details before ordering.

Lock manufacturer and key number: check the existing key, lock face and any manufacturer markings. These may help identify the lock series.
Lock body and fitting dimensions: measure the existing body and door aperture. Confirm the replacement suits the door preparation.
Fixing method: identify whether the existing lock is retained using a nut, spring clip or another mounting system.
Cam length and reach: measure the existing cam and its effective engagement with the frame. Follow the relevant manufacturer's measurement convention.
Cam profile: identify whether the existing cam is straight, cranked, offset or specially shaped.
Door thickness and handing: confirm the door construction and required direction of locking operation.
Keying arrangement: establish whether individual keys, keyed alike locks or an existing master-key system must be maintained.

The existing cam is usually the best starting reference, but matching its length alone does not guarantee compatibility. The lock mounting and locking geometry must also be correct.

Ordering Replacement Cam Locks

Total Locker Service supplies individual replacement cam locks and locks for larger locker maintenance and refurbishment projects.

If you cannot identify your existing locker lock, send us clear photographs of the front, rear fixing and cam, together with any visible key or manufacturer references. Include the number of locks required and whether the existing keying must be retained.

For managed locker installations, consider ordering spare locker keys and any required locker accessories at the same time.

Cam Lock and Locker Cam Lock FAQs

What is a cam lock and how does it secure a locker?

A cam lock is a compact, key-operated cylinder that rotates a metal cam behind a door or panel. On a locker, the cam engages with the frame to prevent the door from opening. Cam locks are commonly fitted to metal and laminate lockers because they are straightforward to operate, maintain and replace.

Can I replace a locker cam lock without replacing the locker door?

Yes. Most conventional locker cam locks can be replaced independently of the locker door, provided a compatible replacement is available. Match the lock body, door aperture, fixing method, cam profile and locking position before ordering. Existing lockers usually require no modification when a correctly matched replacement is fitted.

What is the difference between Lowe & Fletcher 31/33 and Probe 36/38 cam locks?

The Universal 31/33 and Probe 36/38 cam locks use the same underlying Lowe & Fletcher mechanical design. Their principal difference is the key bitting and associated key series. Select the correct series when replacing an existing lock, particularly where existing keys or master-key access must be retained. Check the supplied fixing hardware and cam arrangement as well.

How do I measure a replacement locker cam lock?

Measure the existing lock body and mounting aperture, then identify the fixing method, cam length, offset and locking position. Check the locker door thickness and compare the measurements with the replacement lock's specification. Cam length alone does not confirm compatibility because different cam profiles can produce different locking positions.

Are all locker cam locks interchangeable?

No. Locker cam locks vary in cylinder dimensions, mounting arrangements, cam shapes, handing and key series. Even locks that look alike may use different keys or fixing hardware. Identify the original mechanism and compare its specification with the proposed replacement before ordering.

What is the difference between keyed alike and keyed to differ cam locks?

Keyed alike cam locks allow the same key to operate multiple locks, making them useful where authorised staff need shared access. Keyed to differ locks use separate key combinations for individual lockers. The available arrangements depend on the manufacturer and lock series.

Can locker cam locks be supplied with master-key access?

Yes. Selected locker cam-lock ranges support master-key systems, allowing an authorised master key to operate multiple individually keyed locks. Compatibility depends on the manufacturer, key series and existing system. Provide the original keying details when ordering replacements for a master-keyed installation.

Can I order a replacement cam lock using the existing locker key number?

A key number or lock code can help identify the manufacturer and key series. However, it may not identify the lock body, fixing method or cam dimensions. Total Locker Service can use key references alongside photographs and measurements to help identify a suitable replacement.

Do I need a new cam lock if I have lost my locker key?

Not necessarily. If the existing cam lock is undamaged and its key number can be identified, a replacement key may be sufficient. Total Locker Service supplies replacement locker keys for many recognised lock series. If the mechanism is damaged or the correct key cannot be identified, a replacement lock may be required.

Which cam lock should I buy for a Probe, Pure or other branded locker?

Start by identifying the existing lock manufacturer and key series rather than relying on the locker brand alone. Total Locker Service supplies Universal, Probe, Pure, ASSA and Ojmar cam-lock options. Match the lock body, cam, fixing arrangement and keying requirements to confirm which replacement is suitable.
