Start with the simple and disconnect your power door lock switch one by one. Start with the drivers door lock switch, once you have that switch disconnected.
Try to lock your doors with the fob keys, if it works fine and your battery does not drain over night. Then replace the switch or try cleaning it with electrical contact cleaner.
Good luck and keep us posted.
