UPDATE:
After checking this vehicle out a bit further, I realized a few things:

• the drivers side door will only lock with the key, when I press down the inside door locks, they all go down, except the drivers door remains unlocked. I don't know if this is a actuator problem in the drivers door perhaps?
• When I unlock the car with the key, the alarm goes off when I try to start the car.
• The only time the alarm does not go off, is when the car thinks it's locked. I.E. if I lock the door again via the key before getting in and starting it, or if I leave the drivers door "unlocked" since when I lock the doors the drivers side doesn't actually lock due to the suspected actuator problem.

So now I have 2 problems instead of just one. If anyone has any thoughts to either the alarm or the door lock problem feel free to help.
