Key frozen in ignition of Mazda 3..
My Mazda 3/2012 wouldn't allow the key to come out of ignition after driving.
Had to leave key in over night. Next day holiday, car started and drove it, but
key wouldn't come out. In morning car battery was dead, had a box hooked
up to car, and friend was able to remove key. Mechanic came, removed
battery to test, low voltage, so replaced battery. Was it strictly a battery
issue, or is there an ignition issue, key fob issues, both?
