Using BMW key fob door unlocks saloon vehicle, internal dash mount button opens and locks all doors. However, keyfob remote will not lock the car. I have checked the fuses and relays and they are all ok. What could it be?

    How have you checked the relays? E90s are notorious for this and it is usually a relay in the passenger compartment. Either that or a faulty footwell module or button in the key fob. Commented Nov 19, 2016 at 14:20
