About half the time, when I try to start my van, the key won't turn in the ignition. There is a crank, there is fuel injection, there is also engine turnover. But for some reason the "magic" does not occur.
I tried both keys that came with the van (bought new), as well as a spare. Interior lights, head lights will work. Equipment lights, clock etc do display; everything works as it should pre-ignition and post-ignition.
I checked with a mechanic - and he stated it might be a security problem with the "keys." However, after checking with Chrysler Support, there is no malfunction with the security light/l.e.d. and the key is recognized by the Engine on-board computer. Remote unlock/lock works and the panic button also works.
Van has 3.3 V-6 engine, 150k. Checked for recalls was negative; did not locate any service bulletins.
Any suggestions?
