Gen 3 Prius Door Lock issue

Newbie here... I've been reading through the forums and can't seem to find the right solution to my issue.

1. None of my doors lock using the switch on either the drivers side or the passenger side. y
2. The only way to arm the alarm is to manually lock all doors, close the door and then use the FOB to arm the alarm.
3. The FOB won't lock or unlock any of the doors. I've tried leaving one door at a time locked to see if the any of the doors would lock / unlock to no avail.
4. When I hit the unlock button on either the drivers side or the passenger side door, I hear a click near the internal fuse box but nothing near the doors.
5. The fuse appears to be good. I've replaced it with another 25A fuse and still no go.
6. I don't hear the clicking noise (obviously) when I pull the fuse out and then hit the lock / unlock button on the passenger or drivers side door.

It seems like there's a problem with a module somewhere that delivers power to all of the actuators but I have no idea where that is. could this be some battery related issue? Should I just take it in?

 

Thanks for the quick response. I don't mind DIY'ing this thing but likely won't have the tools or the time to do so. I'm going to assume it's not an actuator given that the odds of all four breaking at once seems highly unlikely. I'll check with some shops to see what they say.

Just wanted to check to make sure I wasn't missing something obvious.

 

Haven't check that one yet. Are there any other symptoms that I would see if I have a 12V battery issue (i.e. power windows are all super slow.)
