1992 Crown Vic, ignition switch not unlocking

Any ideas? I have replaced the commutateur interruptor switch on the under side of the steering column, and also am putting in a new ignition switch (with key), The problem I am having is the shaft, which slides back and forth, with the hole for the commutateur interrupter switch pin does not slide back far enough for the key to be released from the new iginition switch. It seems there might be an adjustment needed, or maybe another broken part to replace. Any ideas will be appreciated. Thanks

Is the shift lever all the way in Park. What have you had a problem with that had you replacing these parts?

Re: 1992 Crown Vic, ignition switch not unlocking

For part of the last year, the key was not really required to turn the ignition switch, but it would not go all the way counter clockwise to locked steering position. Thus the car was vulnerable to stealing once a person was able to enter the car. Also the keys left in ignition bell sound was constant when the door was open, even though the keys where not in, the steering was not locked. I replaced the Commutateur Interruptor Switch last year, which had a lifetime warranty, so I thought it was the part that failed. I removed it yesterday and traded it for a new one under warranty. While I was replacing this, I realized the key was getting very hard to slide into the ignition switch, and finally would not go in at all. Therefore, while I had everything apart, I removed the ignition switch and purchased a replacement, with keys, from AutoZone.
When I went to re-install, I realized the sliding linkage rod, that has the Commutateur Interruptor Switch pin hole, will not slide back to the furthest rear position (towards driver), therefore not allowing the steering and switch to go into the locked position and allow for key removal.
