| Brand | Type / Series / Model |
|---|---|
| JCB | Backhoe Loaders: 2DX, 3CX (Older models), 4CX (Older models) |
| JCB | FASTRAC |
| JCB | Wheel Loaders |

The list above is for reference. It is crucial to verify the length (590 mm) and type of lock in your machine.
When replacing the lock, we recommend checking the condition of the outer handle (with key), the inner handle, and the door gas strut, which prevents slamming.
A faulty door lock poses a serious risk. It can lead to the door opening unexpectedly during travel or operation on a slope, which risks the operator falling out of the cab. It also protects the machine from theft and vandalism.
The 123/02451 lock is a latching mechanism hidden inside the right cab door. It is connected by rods or cables to the inner and outer handles and (in some cases) the key barrel. Its job is to securely latch the door in the closed position and release the latch when a handle is pulled.
