I am having trouble turning the ignition key in my 2007 Hundai Sonata
Do you have more than one key, and is the ignition difficult to turn with both keys?
Wiggle the steering wheel a bit while you are turning the key. Sometimes the steering column lock interferes with the ignition switch.
Sure you’re using the right key? Sounds like a problem for your dealer.
Do you have lots of keys and things on your key ring? That extra weight can help wear the lock.
