Master Door Lock Switch - 2011 528i

The master door lock switch for the 2011 BMW 528i (F10 chassis) controls central locking from either the center console or driver's door panel. For the center-console location, BMW part number 61319175657—superseded by 61319323444—serves as the primary replacement, while door-mounted controls use assembly 61319216048. When junkyard hunting, target 2010-2016 F10 sedans, F11 wagons, or F07 Gran Turismo models; all engine variants (N52, N55, N57) share these switches regardless of horsepower rating. Inspection requires testing button tactile response—sticky or mushy travel indicates internal contamination—and checking for green connector corrosion common in humid climates. Installation demands battery disconnection to prevent airbag faults and plastic trim tools to avoid marring the center console wood or aluminum trim. Common failures include unresponsive locking action or LEDs failing on Comfort Access-equipped vehicles. Always verify the electrical connector matches your production date, as early 2009-build F10s used a 4-pin connector later updated to 6-pin.
