Thinking I need a new Smart Junction Box/BCM due to my key fobs both being intermittent and now TPMS system error. So I got the part number from the current box and found several on ebay. HOWEVER, when (just for kicks) I called the local Ford dealer to see if they had it new (they do for $650) - they looked up the part number based on my VIN and it is a different part # than is currently in place. Makes me think the box has been replaced before using a different model number box and then...

Smart Junction Box Part number - may not be car's original...
