ignition lock will not turn off all the way & you can not remove the key.

What is your question?

ignition lock will not turn off all the way & you can not remove the key. The key turns part way & sticks. The lock has been tested OK. There is no problem with the shifter. If you keep turning it on & off it will go to lock position & come out. There is no problem starting or shutting off the truck.
