Lock(L) Door – Mazda (BDTS-59-310D)

Lock(L) Door mounts inside the Mazda door shell and takes the wear that repeated use puts on the door. Genuine Mazda part number BDTS-59-310D.

The mechanism wears before the panel does, so a door that drops, sticks or will not latch usually needs this part rather than a new shell. Front and rear doors use different part numbers even when the handle or hinge looks identical.

Access is from inside the door, so removing the trim panel is part of the job — order new panel clips if the originals are brittle.

Doors Lock(L) Door replacement for Mazda. Cross-check the part number against the component you are removing before ordering.
