Gas gague shows zero; steering wheel column will not move, fule door will not open from inside; trunk will not open from inside or with the key fob, drivers side seat belt adjustment does not work, buttons on the steering wheel do not work, the horn does not work.

Change the batteries of the key fob

or chnage the car battery

No mention of make/model but does key fob open doors OK? If so it isn't the fob batteries... Could still be a bad button on the fob but it could be a balky solenoid on the trunk latch. Maybe try 12V direct to the solenoid?

Sounds like the R/F transmitter in your key fob has malfunctioned. Get the dealer on the phone. They are probably the only ones who can help you.

I have a 2003 Nissan Sentra and have had this problem myself. When you operate the slide switch that is left of the steering wheel on the dash or push the trunk button on your key fob, can you hear the solenoid click, but the truck doesn't open? If it does, open the truck with your key and raise the lid. I found that the lever assembly in the bottom lock was hanging up. I lubricated with WD-40 and using a small screw driver I moved the levers until they moved smoothly. Then activated the key fob switch and it started operating. If the solenoid doesn't work then there probably is an electrical problem. Let me know.

Take your key and go to the drivers door, make sure the door is unlocked by pulling on the handle, open and close the door. Insert the key and "lock" the door, double check that it is locked by pulling on the handle. Insert the key and "un-lock" the door, use the handle to open the door and now press the fuel door key and it should open, same for trunk release button.

Audi's are a strange breed, sometimes you just need to "re-set" some stuff. But in the future if you lock the car with the key, the fob will unlock the car but the three buttons in the console will not work, the fob will function correctly.

I hope this helps.

Yes, insure that you have power to the trunk lock inside trunk, If not could be lose/broken wire or shot fuse. I am sure the key fob does work for the doors? If not have key fob battery replaced. Also, a quick check on power to trunk lock, check to see if have remote power button inside car, if it works power is good. Defective key fob would then be indicated.

there is a wiring harness that runs down the column some where the wires are bear and touching the column all you have to do is find them and tape them up so they dont touch

To get inside the car .... Use the key in the lock cylinder, unlock the drivers door to get inside. You shouldn't have to reprogram the fob unless it or the keyless module was changed. There may be a blown fuse that supplies the keyless control module (check the owners manual for location). or wires that lead into the Drivers door may be damaged ... The keyless module is located inside the drivers door at the bottom behind the door panel ... do the unlock/lock and trunk release switches on the inside of the drivers door operate the locks and or trunk release? If so it is not the fuse ... and not the wires to it ... And it could be your BCM body control module, located in the dash board to right of your gas petal. Because the number entry keypad (code for that is on the inside of the right passenger trunk bracket arm) also doesn't work I assume it's not the key fobs themselves. Your 98 manual is correct for your car.

Horn problem is either bad horns or failed clockspring behind steering wheel which is the connection for the airbag and horn buttons.

There is an emergency key for just this situation.

Use it to pry the keyhole cover off the left (driver's) side of the rear bumper. The pry point is at the bottom of the cover. Insert the key, unlock the trunk and lift it open, it's not too heavy.

Open the little door on the left side of the trunk, near the back. It has a gas pump on it. There are 2 tabs inside. One opens the gas cap. The other unlocks the drivers door. Now you can get into the driver's side of the cabin.

Below and forward of the button to release the hood on the left side of the steering wheel, is a manual hood release. Pull it and release the hood.

Now you should be able to open the hood and charge the battery to make everything work again.
