Original BMW Remote Key Ignition Lock for BMW 3 Series and M3 (2006–2013)

For E90-generation BMW 3 Series and M3 models from 2006–2013, this Original BMW ignition lock is the ignition lock of remote control used to start the car. BMW calls it the ignition lock of remote control. It is made in Germany and sold as one assembly. With age, the internals of the lock wear until the key will not go fully into the slot, and the car may not start. Fitting a new assembly restores that function. The lock is the point where the driver's key meets the starting system, so it is used every time the car is driven.

Original BMW Parts carry a 24-month parts warranty.

BMW supersedes the earlier lock 66 12 6 954 719 with this number and rates the change as backward compatible, so the new assembly also fits cars built before production of 66-12-9-172-371 began in December 2007. Another earlier number, 66 12 6 937 494, also crosses to this part. One assembly covers all four body styles: the E90 sedan, the E91 wagon, the E92 coupe, and the E93 convertible, both before and after the facelift.
