I am trying to figure out what technically happens when I press the door open button.
What wires does it connect to open the door?
I would somehow like to attach a remote controller to wires.
Is this possible?

AC1 and D0 will be shorted to operate the door open solenoid.

You could use a wireless doorbell as a simple remote - to activate a relay with contacts connected across AC1 and D0.

You should be able to trace the copper tracks on the printed circuit board from the 'door open' button to the appropriate terminals.
