It is more than likely your buttons, if one button is bad neither will work.

Try changing the buttons, if that does not work, then it could be one of the motors,
same as the buttons if one is bad neither will work.

to change the buttons, simply remove the screw on the panel, if there is one, if not then insert a small flat head screw driver on the bottom of the panel and gently push down this will pop the panel out.

once you get it out pull the plug off, there is 2 8mm screws holding the switch in, then screw your new one in and plug it back in, do the same on the other side. the panel will just snap right back in.

If this does not work, check the motor, you have to remove the door panel, then the silencer pad, once you get in, it will be inside the door near the back. about half way down, it is round with a rubber boot, it is held in with some rivets. If you need to replace it you will have to drill them out, and replace with nut and bolt.

To test it, if you have a corless drill... pull the plug from the motor, and stick 2 wires into the plug, one for positive and one for negitive, and touch the ends to the battery. if it does nothing then it is your motor, but make sure you switch the wires from one side ot the other to test both up and down.
One wire is for up and one if for down.

If you do not have a cordless drill battery just use long peices of wire and use the car battery.

Don't worry there is not enough power in a car battery to shock you.

depending on how the car is set, the unlock may have to be depressed twice to unlock the passenger door. i'm guessing you have already tried this? if not give it a shot.

if that didn't fix it, then sit in the car and hit the unlock button twice and see if you hear the passenger door unlock/lock mechanism trying to unlock the door. if you can hear it trying to pop the lock, then it may be an issue with the cold. my '99 323 was this way in the cold. if you can't hear it trying to pop the lock, then the module in that door is bad.

also when was the last time BMW replaced the battery in that key?

good luck.
