Ignition locking up what do I do?

No... The ignition lock cylinder needs to be replaced.. The part the key goes in... Not a bad job if handy with auto repair.. Now don't mess around... Fix it or have it fixed before it locks up and you can not turn the key at all because it has got to be in the on position to remove the lock cylinder!.. You'll get new 'ignition keys' with the new lock cylinder.
