So when I goto to turn the engine off...normally I have to depress the key into the ignition then turn the key more left before I can fully remove the key. This just started....now when I depress the key into the ignition, I can no longer turn it left....thus, I cannot remove the key from the ignition. I can jiggle it all different ways and still nothing....the only way to get it to work is to restart the engine....then it will usually work properly. How will I fix this??
