This is really weird. My key won't turn in the ignition of my 99 Grand Marquis. I tried jiggling the steering wheel, flipping the key over etc..., but it still won't go. The steering wheel lock works (as it's locked), key is in good shape, the battery is connected, lights come on etc..., key just won't turn.
I changed the fuel filter today, and the car started up no problem after that, so I`m stumped.
Any ideas? Thanks.
