I cant get my ignition key to turn all the way back into the off position.

Put key in turn key to on position pull cylinder out turn key back and remove key. Thats how I did it on my 94.

Push in turn back all the way. You may have a lever u have to push or its not in gear all the way as in park.

Most vehicles you have to have power to remove the key from the ignition. It will go in and turn, but not completely turn back to the off position.

u need to replace the ignition lock cylinder

TRY THIS IT MAY OR MAY NOT HELP.PUT KEY IN THE IGNITION SWITCH TURN IT TO ON POSITION WITH THE ENGINE OFF.LEAVE KEY ON POSITION THE IMMOBILIZER WARNING LAMP ILLUMINATES FLASHES.IF WARNING LAMP TURNS OFF IN 30 SECONDS TRY CRANKING CAR.SEE IF IT RUNS WITH OUT CUTTING OFF IF SO.THE AUDI DEALERSHIP HAS TO REPROGRAM THE NEW IGNITION KEY. WHILE THE KEY IN THE IGNITION SWITCH IN THE ON POSITION AND THE WARNING LAMP DONT STOP BLINKING THE DEALERSHIP HAS TO REPROGRAM KEY TO THE IGNITION SWITCH AND IMMOBILIZER.

first thing to try would be to remove car from park to a gear and then put firmly back into park...... then retry,
if doin that a few times dont work, you will prob need to replace the ignition cylinder....... make sure it appears gear selector levers parts are all in their place,, visually that is

Make sure the gear selector is fully in park, alot of times if the cars wheel was turned when the vehicle is parked the steering wheel is locked in the turn position and it puts pressure on the ignition switch. Try turning the steering wheel slightly left/right and see if it kicks back. If it does you have tension on the ignition and need to hold it until the key is turned to the on position and it unlocks the ignition. If you can try to let the wheel come to a rest before turning off the ignition as opposed to holding the wheel turned and shutting off the ignition, this will avoid a locked wheel/column

Sounds like a very warn out lock and tumblers. Try angling the key as you turn the lock.

Jiggle the steering wheel back and forth while trying to get the key back in. Keep jiggling the wheel while turning the key until it all works out.
