I have the usual problem with the key not being able to turn the lock on my 84 300SD. HOWEVER, in my case it is a problem with the tumblers. I tried all the vibrating, upside down, etc. suggestions to get the key to turn. All to no avail. Now the key is broken off in the tumbler. I am resigned to buying a new housing, tumbler/keys, and ignition switch.

My question is this. Can anyone tell me the easiest way to get the wiring harness disconnected from the old housing/switch WHILE the key CANNOT be turned to the first "on" position? The tumbler is locked in the off position. I could put the housing in a drill press and drill out the tumbler (in order to salvage the tumbler cover) if I could get the harness disconnected from the back of the ignition switch. All advice I have found for removing the harness says to put the key in the "on" position. This I cannot do.

Thank YOU!
