Door locks

Alright so this car has been sitting for awhile and we just started getting it fixed, now i've begun driving it and i've noticed that now i have to open all the door locks manually from the inside (once i open the drivers door). Not like the usual when i would just have to turn the key on the drivers side and they all open/lock. It's not like it's gonna kill me lockin and unlocking them but it's much more convenient to just turn the key.

So if anyone knows what this could be please post it cause the only thing i thought it was, was the fuse and that was not it.

Thank You
