This used OEM BMW ECU DME / Cas3 Theft Locking Module / Lock Cylinder w/ Key (part 7645764) comes from a donor vehicle. It also replaces 9227053, 8661467, 8631728, and other numbers in the 86/86/76 series. Designed for a 2.0L turbocharged four-cylinder, this module combines engine control, immobilizer, and ignition functions. A common failure symptom is the key not being recognized or a no-start condition. Programming is required—it must be coded to the vehicle’s VIN by a qualified shop or dealer upon installation.
