I have a 1999 Chrysler Town & Country Van. The ignition was locking up on a regular basis. I finally had the ignition assembly replaced but it is still locking up. If I hit the ignition with a small flashlight I can tun the ignition and start the car. My wife is the primary driver of the van it this is extremely frustrating to her. She is afraid she won’t be able to start the car and be stuck somewhere.
You might try to find a lock shop that works on vehicle systems to see if they can find out what is catching. They may be able to fix the trouble.
Automatic or manual?
