Lock button – BMW diagram

Callout 04 on BMW’s drawing “Door lock front”. Open the drawing →

Also shown on FRONT DOOR CONTROL/DOOR LOCK, FRONT DOOR CONTROL/DOOR LOCK.

This is a genuine BMW lock button, part number 51 21 1 805 643. You will find it under Interior Body (Other Body equipment parts). It supersedes the older number 51 21 6 754 240, so a part carrying that number is the same part.

Fits E36 318i, 318ti, 323i, 325i, 328i and M3 (1992–1999), coupe, convertible and compact, with the M42, M43, M44, M50, M52 or S50 and other engines.

BMW draws it on 34 drawings, among them Door lock front and Front Door Control/Door Lock. BMW's catalog calls for two of these at each place it is fitted.

Out of stock. Request it and we will notify you when it is in stock.
