Mini Door Lock FAQs
Why do Mini door locks say BMW in the title?
Mini is part of the BMW Group and shares many parts with BMW, including door locks. A lock with the same part number fits both, so you'll often see BMW and Mini on the same listing.
Where do I find the part number on my Mini door lock?
It's on a label on the lock body, usually starting 5121 (front) or 5122 (rear). You'll need to remove the door card to see it, or send us your reg and we'll check for you.
Is the actuator separate from the latch?
On these Mini models the motor is built into the latch, so the complete lock unit is replaced.
