Both key fobs do the same thing.
Both doors dont lock or just one?

The relays are located on the bcm
the one you want is the dr door unlock pcb.

If the inside butttons work the relays are fine.(The fob and buttons both use the same relays, controlled through the bcm)

There is a fuse there on the bcm for the locks if you want to check it and while your there push on the relays to make sure they are seated,
