About this part

Door locks on your CX-30 DM secure your vehicle via the central locking system, key fob and immobiliser. A faulty lock that won't engage or release properly compromises your vehicle's security.

Frequently asked questions

What should I check when ordering a replacement door lock for the Mazda CX-30?

Confirm the door position (front/rear, left/right) on your CX-30 DM and whether you need just the lock actuator or the complete lock assembly including the cylinder.

Can I replace just the lock actuator?

On most vehicles yes – the actuator motor can be replaced without changing the entire lock. This is often the more affordable fix when the mechanical lock still works.
