Key sometimes stuck in ignition

Recommended Posts

Been having this problem a lot. Sometimes, it will come out the ignition after the car is off and parked. No issues there, par for the course. But other times, after I park the whip, put it in park and turn off the ignition, even while trying to gently pull, it will get stuck. Is this common for the 2006 Zephyr (MKZ)?

Some early Fusions and Zephyrs had this issue.  There was a TSB for it:

Some 2006-2007 Fusion, Milan and 2006 Zephyr vehicles built before 9/4/2006 may exhibit a customer concern of the ignition key getting trapped or a shifter slider binding condition. Most Of the key trapped conditions are caused due to a binding shifter button which does not allow the pawl to contact the park detect switch.

Even if your car is not in this build range, binding in the shifter mechanism can cause this. There's a solenoid that has to get a signal in order to release the key in Park. If the button on the shifter doesn't fully release, no electrical signal is sent.  The next time it happens, see if the key will come out with the selector in Neutral.  If it does, you have a shifter/solenoid issue.
