Was the factory preset saver tool install d before the battery was removed? If not then the BCM lost all its memory, so now it will have to go to the dealer and have the system reflashed to match the vehicles vin. Usually runs about a hundred bucks. There is a warning in the owners manual about the total loss of battery power.
