Q: Key won't turn in 1996 Mercedes-Benz E320

asked by on

Ignition key won't turn.

If the key wont turn normally try to jerk the steering wheel side to side while turning the key. If this does not free up the ignition then the ignition switch is likely the cause. When tumblers inside the ignition switch fall out of position they can cause the switch to jam up preventing the key from turning. Have a qualified service professional come to diagnose and repair this issue.
