200q driver lock situation

[WLAMB@denver.echobay.com]

     This morning as I locking my '89 200q in the parking garage, there was
     funny pop sound as the key turned.  The door (and the other doors)
     did not lock but the alarm was armed. I went to the passenger side and
     locked the car.  Any insight on what broke in the driver's door?  
     Anybody been here before?  I have seen the serpentine capillary tubes 
     for the automatic door locks when I have replace window switches, --oh 
     boy am I in line for another real Audi engineering learning 
     experience? 
     
     Thanks in advance for any help/thoughts.

     ps I have the Bentley books so I am armed and dangerous....
