Change the batteries. The remote can be opened via screw or will have to be pried open with a screwdriver. Inside you will see the kind of batteries needed, which will most likely be available at Radioshack or similar stores.

You don't describe your problem, but that car should have had its power steering fluid replaced a couple of times by now, so if it has not been done, replacing the fluid might help whatever your problem is.

When was last trans fluid & filter change? (I'm assuming it's an auto. trans.) Trans fluid & filter should be changed every 30k or 3 years. I'd start there and have system flushed when you do the filter change.

Sounds like white smoke is antifreeze. It might be leaking all of the time. Does your antifreeze level fall gradually over a week's time?

Virtually all of the electronics for the door locks are in snap-in door lock modules that are easily replaceable. All four doors use identical modules, so if you get one from a junk yard, get one from a different door that likely has less use than the driver door. New OEM modules sell for $60 on line.
Make sure that the module and the mechanical door lock are in the same 'state' (locked or unlocked) or the hole won't line up and it won't snap in. Compare the new one to the one you pulled out to get it in the correct position.
Disconnect the battery several minutes before you touch the air bag in the door, and do not reconnect the battery and turn on the key while the air bag is unplugged. If you break snaps getting the door panel off, no worries, the snaps cost less than a buck a piece.

If you can get the key out, flip it over, or try a different key.

Most of us end up removing the whole housing because getting the lock cylinder out of the housing when it is 13 years old is nearly impossible. In theory, you can push a stiff wire or drill bit into the hole in the lock face when the key is turned to the second click and you should be able to release the lock cylinder. Works with a new lock and housing. Does not work with an old one for some reason.

To replace the housing, you will need to remove the steering wheel. Disconnect the battery several minutes before disconnecting the air bag. You will need to remove the plastic cover from around the steering column. It is hard to take off and harder to put back on. Takes about three hands to get everything back in the right position all at once.

When you pull off your steering wheel, be careful not to damage the clock spring connection for the air bag, and note carefully the orientation and position of the two bushings. They are easy to put back wrong, and if you do, the steering wheel will rub.

Be sure to lube your top steering shaft bearing while you have the housing off.

A dremel tool works well to cut slots in the security bolts. Then a short straight blade screwdriver bit turned with a small ratcheting box end wrench is the easiest way to unscrew them.

You will probably want a new key to go with your new lock because the key is probably pretty worn as well.

A short piece of 3/4" PVC pipe pressed down by the steering shaft nut is the best way to put the snap ring back in its notch in the steering shaft

New lock cylinder + new lock cylinder housing + new key = $$$ Many of us with 90s vintage BMWs have felt your pain.

This is a question you should pose to a salvage yard, or better yet to one of those salvage parts finder services on the web. That is a popular part for cars of this vintage, so good luck.
I presume that you have ruled out the wheel sensors and wiring and have determined that the ASC control module has failed?
BTW, the most common cause of an ASC warning light on this vintage BMW (after damaged wheel sensors) is the ASC throttle (aka Secondary Throttle) which is right next to your regular throttle. If its cable is bound, or its electrical connection is damaged, or anything (such as the throttle boot hose clamp) interferes with the action of its throttle plate, it will prevent the ASC from working.
