This is a genuine BMW repair kit one-key locking system, part number 51 21 8 194 540. The number stamped on the part is 51218194540; BMW's catalog files it under the short number 8194540. You will find it on our Interior Body shelf, under Other Body equipment parts. It supersedes the older number 8161718, so a part carrying that number is the same part.

It fits the E36 sedan, coupe and compact (318i, 318ti, 320i, 325i and M3, 1992–1999), with the M40, M42, M43, M50, M52 or S50 engines — and the European-market versions.

BMW draws it on the One-key locking (41_1085) diagram. It weighs about 1.6 kg (3.5 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
