Volvo is full of BS on the keys. Looks like all the cars wither shipped or were programmed with 3 keys. When you try and pair top Volvo on call it wants all the keys in the car and it you only have 2 it will fail saying you need all 3 keys. Oh so you go and buy a third key and get it programmed by dealer and try again, now it says it needs all 4 keys. Volvo will give you all these excuses, but they have no idea what is going on. If you scream loud enough about having only 2 keys they will comp you the third key, just get your dealer to delete the missing key from the car.
