A6 ignition issues

[DOUBLDz at aol.com]

Hello,

New troubles have turned up with Baby involving the ignition (I think). Last 
week, I couldn't get the key out of the ignition after shutting her off. Then 
there were times too when I couldn't turn the key to start her up. I brought 
her to my trusted mechanic and the ignition was replaced...the car has been 
there since Tuesday...special ordered the parts, etc., got her back Friday 
night, well almost. The service manager drove the car from the garage to the 
front door for me because it was raining, but when he tried to remove the 
key, guess what? 

So I left the car with him again and they will try to find the problem on 
Monday. Frankly, while I've always trusted them, I'm nervous right now. Its 
seems very possible that the ignition did not have to be replaced and that 
something entirely different, possibly electrical, is actually the problem. 
If I could point them in the right direction on Monday, it would be a big 
help. Any suggestions?
