284B2-1NC0B doesn't show up as a good part number, so I have no idea what's in your car. BCM part numbers can be supersessions, but they need to be correct for the car's VIN, period. "Close enough" can render your car completely inoperable. Also, be aware that you probably can't program your existing keys to a used BCM. In general, to employ a used BCM you need new keys, to employ used keys you need a new BCM.
