Key will not unlock doors after battery change

[gdtnrbr]

Hi this is my first post. I have scoured this site and the web for help on getting my keys working again. I have an 02 x5 3.0i that runs great. Recently replaced the battery myself (very easy job) and found all the electrical to be normal except the keys won't open the doors remotely. They will open the tail gate/hatch. The cabin light will come on as if the doors were being unlocked, but no locking action. The car acts normally when the keys are physically used to lock/unlock the doors.

I have been through the whole reprogram the key bit several times using just about every variation imaginable. That would be the "hold down the unlock button and click the lock button 3 times" while barking at the moon etc etc etc. I'm beginning to think that its not the keys, but the car.

The locks do work when using the keys in the door. Probably not a fuse issue.

Any suggestions? I'm trying to avoid the trip to the dealership for obvious reasons...
