Used Mazda 323 Central Locking Motor

Yes, central locking motors (also called central locking actuators) were fitted to many Mazda 323 variants, typically as standard or optional equipment depending on the trim level and generation. The 323 was produced across several generations, and central locking became increasingly common from the BG generation (1989–1994) onwards through the BH/BA and BJ generations. If your car has central locking at all, it will have these motors — one per door, and sometimes the boot or tailgate too.

The BG and BA are distinct generations with different door internals, so the actuators are unlikely to be a straight swap even though the function is identical. The physical mounting points, rod geometry, and connector plugs can differ between generations. Confirm the part number or have the breaker compare against your registration before buying.

The BJ generation ran from 1998 to 2003, and actuators from within the same BJ generation are your best starting point for a match. That said, confirm with the breaker whether the specific door position (NS front, OS rear, etc.) and connector type match your car, as minor running changes can affect plug compatibility. Providing your registration to the breaker is the most reliable way to ensure you get the right unit.

The central locking actuator itself is determined by the door and generation, not the trim level — a GXi and a base-spec 323 of the same generation use the same motor in the same door position. What may differ is whether lower trims had central locking fitted at all; if the donor car in the breaker's yard is a base model without central locking, it simply won't have the actuator to sell. As long as both cars have central locking and are the same generation, trim is not a fitment concern.

These are different models with different door sizes and internal structures, so direct interchangeability is unlikely even though Mazda used common components across its range in some periods. It is possible that certain actuator units were shared, but this is not something to assume — the rod lengths and mounting clips in particular can vary. Ask the breaker to check part numbers against your registration before purchasing from a different model.

On many cars the actuators themselves are symmetrical and the same unit can be used on either side, with only the rod or clip arrangement differing. However, this is not universal, and some doors use mirrored or side-specific units. Check with your breaker whether the BJ rear actuators are handed or interchangeable before ordering.
