Have the old door or lock in front of you before choosing parts. Measure the outside frame and cut-out, note the hinge side from outside the caravan, and take a clear photo of the lock, handle, barrel and catch. These details usually decide whether you need a complete door, a lock body, a handle kit, a barrel, a blind or an access-door part.
Replacing the whole door? Measure before choosing
For a full entrance-door replacement, start with caravan doors, boots and parts and measure the cut-out as well as the outside frame. Also check hinge side, corner style, colour, wall depth and whether the door includes a screen, blind or vent. Camec/Odyssey and Aussie Traveller doors have different generations, sizes and corner styles, so the old door is the best reference.

Fixing a lock? Match the lock family first
If the door will not lock, latch or open cleanly, identify the lock family before buying parts. A Camec 3-point lock, Trimatic lock, Panorama lock, Dometic/CARAD lock, Milenco Columbia lock, Jayco camper lock and Thetford/Zadi service-door lock use different parts. Use door locks and catches for the broad range, then narrow the choice by the old lock body, handle shape, barrel, latch and catch-pin position.

Camec 3-point locks need the exact part
Camec 3-point parts are common, but they are not all the same part. Before ordering from Camec 3-point lock parts, decide whether you need the main lock body, a complete lock kit, outer handle, inner handle, barrel and key, catch pin, strike plate or remote latch. Left/right hinge and door-frame depth can change the answer. The Camec caravan doors guide and the Camec lock spare parts diagram are useful checks before guessing.
One-Key only works with compatible locks
Camec One-Key can be handy when you want matching keys across compatible doors, boots, water fillers and access locks. It does not make every old lock compatible. Check the lock housing and barrel style first, then use One-Key solutions and the Camec One-Key guide to confirm the right barrel or adapter.

Blinds and access doors are separate checks
Door blinds are usually matched to the door model and size. Measure the blind opening and frame before ordering door blinds, especially for Milenco Columbia, Camec Odyssey and Aussie Traveller styles. Access doors are separate again: match the cut-out, hinge side, colour, service-door type and lock/barrel before choosing from access doors.
