Q: Key won't turn, Hyundai the steering wheel not locked can't turn at all. Happened before but now key not turning 2007 Hyundai Sonata

Hi there - your symptoms suggest the key tumbler - the actual lock portion of the ignition switch - has a stuck pin/spring combination. I suggest squirting a bit of dry graphite lubricant into the key opening, then insert the key and work at turning the key. Other liquid light lubricants can also be used (WD-40 is the classic, but liquids attract dust and dirt, and have a bit of a smell. For assistance, I recommend a ignition key won’t turn inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
