Used Vauxhall Cavalier Central Locking Motor

Yes, central locking was available on the Cavalier Mk3 (1988–1995), typically fitted as standard or as an option on mid-range and higher trims such as GL, GLS, CDi, and GSi. Each door lock actuator is a small electric motor unit that drives the locking mechanism, so there is a genuine used part to source from a breaker. Earlier Cavalier Mk1 and Mk2 variants are less likely to have had factory-fitted central locking, so if your car is from before 1988 it is worth confirming with the breaker whether your specific vehicle was factory-equipped.

The Cavalier Mk3 ran from 1988 to 1995 across saloon, hatchback, and estate body styles, and the door lock actuator units on the front doors were generally shared across those body styles within the same generation. Rear door and tailgate actuators may differ between body styles, so when sourcing tell the breaker exactly which door position you need — nearside front, offside rear, and so on. Confirm the specific door and body style against your registration to be safe.

The Cavalier Mk3 received a facelift in 1992 with changes mainly to the exterior styling and interior, but the door lock actuator design was not fundamentally redesigned at that point. In many cases the actuators are interchangeable across the full 1988–1995 Mk3 range, but because this is a boundary year question it is worth confirming the part number with the breaker against your exact registration before committing. A good breaker will be able to cross-reference the donor car's year with yours.

For central locking actuators, trim level does not affect fitment — the motor units fitted to a GSi or CDi are the same functional components as those on a GL, provided the car was factory-equipped with central locking. The only thing to be aware of is that very basic or early Cavaliers may not have had central locking at all, in which case there would be no actuator fitted rather than a different type. As long as both cars have central locking, trim is not a barrier to the part fitting.

The Cavalier Mk3 shares its platform with the Calibra (1990–1997) and overlaps with the early Vectra A, and in some cases door actuator components were shared across these models. However, door aperture dimensions and actuator mounting points can differ between models even on a shared platform, so this is not a straightforward yes — confirm the part number with the breaker against both vehicles' registrations before purchasing. A reputable breaker will be able to tell you quickly whether a donor part from a Calibra or Vectra A will match your Cavalier door.

Give the breaker your registration number, the exact door position you need (nearside front, offside front, nearside rear, offside rear, or tailgate), and confirm whether your car has factory or aftermarket central locking. It is also helpful to mention the year and body style of your car, as this helps the breaker match a suitable donor vehicle from their stock. If you can supply the part number from your existing unit that is even better, as it removes any ambiguity.
