Quick reference
CAS modules are VIN-locked and require dealer-level programming (ISTA-P) to function; they cannot be plug-and-play swapped
If vehicle is equipped with Comfort Access (SA 322), there is a separate passive entry control module (distinct from CAS4) located in the rear of the vehicle—verify which component has failed before purchase
Early 2010 production F10 may use unique harness connectors; verify 26-pin connector style matches your vehicle
Context
When sourcing a keyless entry module for your 2011 BMW F10 528i, you're targeting the CAS4 (Car Access System) control unit mounted at the steering column base. Valid interchange candidates carry OEM part numbers 61359215446 (early CAS4) or 61359264969 (CAS4+), fitting all 2010-2016 F10 5-Series chassis including the N52B30-powered 528i through 2012. These modules also interchange with F01/F02 7-Series and F25 X3 platforms sharing the same hardware generation. Critical: BMW CAS modules are VIN-locked to the specific vehicle; installation requires dealer-level programming (ISTA-P) to synchronize with the DME and EWS immobilizer—purchasing a used module without programming resources is inadvisable. Inspection priorities include examining the 26-pin connector for green copper corrosion (indicative of footwell water ingress) and confirming the aluminum casing hasn't suffered impact damage. Check the hardware stamping (9215446 or 9264969) on the module face, as labels often fade. Production split occurred in September 2012 when BMW transitioned to CAS4+ encryption, so verify your vehicle's manufacture date before purchasing salvage units.

Water ingress from clogged sunroof drains or windshield leaks commonly destroys these modules—always inspect footwell carpeting beneath the steering column for moisture staining before installation
