Ignition is stuck in off posistion

One if the locking tumblers inside the lock cylinder is not positioning itself correctly when the key is inserted.. Jarring the lock cylinder will usually allow the tumbler to drop into correct position.. Striking the key squarely with a rubber mallet sometimes will help - - tapping the lock cylinder with screwdriver tip while trying to turn key may work. Otherwise you’ll need *hands-on* assistance from qualified personnel - we can’t post the entire procedure for lock cylinder replacement here. Good luck!
