This used BMW ECU DME / Cas4 Theft Locking Module / Lock Cylinder W/ Key (OEM 8639594) integrates the engine control unit with the theft-deterrent system and ignition lock cylinder. It also replaces several 86xxxxx-series units, including 8664660 and 8610636. Common failure symptoms include no-start, key not recognized, or security warning lights on the dash. This module must be coded to your vehicle’s VIN after installation by a qualified shop or dealer, as it is VIN-locked and ties ignition key authorization to engine management.
