Ok. Typically, if one of the functions works from an alarm, but the other doesn't, usually what's wrong is either a wire has come loose from the relay, the relay has failed, or the wire has broken or come loose from the alarm/controller module.
The button or slider you would actuate to manually lock and unlock the car from the inside, does it move when the doors are remotely unlocked? The piece sitting on the table next to the solenoid looks like the piece that connects to the visible indicator of the door being locked and unlocked.
The other thing that tells me it might be a problem with the alarm control unit is that you said the remote no longer arms/disarms the alarm.
Is it a factory alarm, or aftermarket? Do you know where the control module is located? Are you familiar with the use of a multimeter? And have one? If the alarm is aftermarket, can you decipher make and model? If so, I can most likely get the wiring information for it.
