Unlocking with the key sets off the alarm + battery drain

[rxmangriff]

My main problem is battery drain. If I don't start and run the car after 3 or 4 days the battery needs to be charged. More recently as I've unlocked the car with the key (my fob doesn't work) it is getting to the point where it sets off the alarm most of the time regardless of sitting or after driving. Not a big thing about the alarm since I just twist the key a second time and the alarm shuts off. I'm wondering if these 2 things can be connected. What is inside the door that could cause this? Is there a switch attached to the lock, etc.? I would much prefer to find something with the door causing the drain vs pulling every fuse to look for a parasitic draw.
