Sad part is that he quoted $250 for the friggin part plus labor! Sheesh. I do not have this kind of money to spend right now.
At any rate, he said he could diagnose it with a PST tool and I could bring the car to his place later this week or this weekend and he had the part in stock.
Just thought I'd report back on this thread for historical purposes for others to read in the years to come when it happens to them.

I have been reading up on your door lock issue before RandallNeighbour, how you have successfully addressed it and the advice others have generously given. In turn, I wanted to request help in figuring out what I should.
Car is a '98 Boxster with M535 option that experienced the water under seat occurrence. Replaced alarm control unit. Main issue is that the key remote control does not lock and unlock both doors. Also, the dash central lock button is not working. The driver's door can be locked using the key but even when locking the driver's door with the key, the passenger door remains unlocked. The remote is however able to open the rear trunk and the red LED on dash blinks when the remote is pressed. So it appears that the key remote is able to send signals.
Curiously, when the key remote control is pressed, the gas cap door pin actuates to lock but almost immediately retracts (and the gas cap actuator makes a buzzing sound in the process) so gas cap door is also always unlocked (even when manually locking the driver's door with the key, you hear a buzzing sound from the gas cap door actuator, and the gas cap door remains unlocked).
The windows drop down a few inches when the outside and inside door handles are used. Even with the emergency three times manual turn of the key on the driver's door, the passenger door remains unlocked.
