Couple of thoughts....
The double beep means there is a problem (fault) with the central locking system. This is different than the single beep which means something isn't closed fully.
The passenger window not dropping could be a couple of things. One, the regulator might be broken. This causes slack in the cabling so the window doesn't drop when the door is opened. Two, the sensor in the door locking mechanism might be reading an incorrect position. Third, the central locking unit itself may not be communicating with the window and / or door.
The best way to diagnose further is to read the fault codes. If you're near an autozone, they might do this for you for free. If you have a Durametic cable or know someone who does, then you can read the codes. It might take two tries. Read the codes first, write them down and then clear. Then when another fault occurs, read it. The second reading will likely be more indicative of the problem than the first.
