Locks do not work after changing battery in car (not by FOB, or by buttong in car)

Hi - let my 98.5 a4 2.8 sit a while over winter without using it. then replaced (car) battery this spring. Since replacing battery, my locks do not work. They don't work at all, not by FOB or by buttons in the car. I can lock/unlock drivers door by using the key, but truck and other doors do lock/unloc.



I don't not have a vag com. Can anyone help me try to get locks working again?
