Is It Your Door Lock Actuator?

These are the most common signs that a door lock actuator has failed:

One door won't lock or unlockThe other doors respond to the fob, but one doesn't.

Buzzing or clicking in the doorThe motor runs but the lock doesn't move.

Locking works only sometimesActuators often fail gradually, especially in cold weather.

Door locks or unlocks by itselfA failing lock unit or wiring fault can trigger it.

For the full list of symptoms and what causes them, see our door lock actuator guide.

Quick checks before you order: if no doors respond, check the key fob battery and the central locking fuse first. If one door fails, look at the wiring in the rubber gaiter between the door and the body pillar, as broken wires there cause the same symptoms. See all checks.

How to Choose the Right Door Lock Actuator

Pick your make from the list above, then your model and year. Locks change between generations of the same model.
Pick the door and side. Front and rear locks are different. On UK right-hand-drive cars, right is the driver side and left is the passenger side.
Match the pin count. Count the terminals in the plug on your old lock (for example 6, 7, 9, 10 or 14 pins). The new lock must match your wiring.
Match the OE number on the old lock's label, such as 3C2837016A (VW Group), LR011275 (Land Rover) or 51217202144 (BMW).
Check RHD or LHD. Some makes, including Volvo, use different front locks for right- and left-hand-drive cars.

Shared Parts Between Makes

Car groups share door locks, so the same lock can appear under more than one make. If the OE number matches, it fits.

Group	Brands that share locks	How to match
VW Group	VW, Audi, Seat, Skoda	OE number (e.g. 3C, 3D, 1P, 8J, 8K) and pin count
JLR	Land Rover, Jaguar	LR part number and pin count (10, 14 or 10 + 4-pin)
BMW Group	BMW, Mini	Part number starting 5121 (front) or 5122 (rear)
GM	Vauxhall / Opel, Chevrolet	GM part number
Ford / Volvo	Ford, Volvo	Ford / Volvo part number
Renault / Vauxhall vans	Renault Master, Vauxhall Movano	805020009R / 805030009R

Single Lock or Pair?

Single lock: the right choice when one door has failed and the others work normally.
Front or rear pair: worth considering on high-mileage cars where one lock has already failed, as the matching lock on the other side has done the same amount of work.

Fitting involves removing the door card and unclipping the handle cables. Always test the new lock with the door open before refitting the trim. Read the fitting overview.

Door Lock Actuator FAQs

Is the door lock actuator the same as the door latch?

On most modern cars, yes. The electric actuator is sealed inside the latch, so the complete lock unit is replaced. That's why many listings are called "door lock mechanism" or "door lock latch".

Why is the same lock listed under different brands?

Car groups share parts. A VW lock may also fit an Audi, Seat or Skoda, and a Land Rover lock may also fit a Jaguar. If the OE number on your old lock matches the listing, it will fit.

Does the pin count really matter?

Yes. Two locks can look identical but have different plugs. Count the pins on your old lock and choose the version with the same number.

Which side is the driver side?

On UK right-hand-drive cars the driver side is the right-hand side and the passenger side is the left, as seen from the driver's seat.

Should I replace the lock or repair the wiring?

If the fault is a broken wire, loose plug or blown fuse, repair that first. If the motor buzzes but the lock doesn't move, or there's no power fault, the lock unit needs replacing.

Can't find your car?
