Ignition will randomly lock sometimes, and key wont turn.
I have a 2001 PT Cruiser and i recently took my car to a mechanic to change my alternator. I got it changed, but afterwards, i encountered a new problem where my ignition locks and the key wont turn, at all. It was like this for days until later i randomly decided to give it another try and it worked! However, after 3 days of my car working fine, one day i am leaving work, get into my car, and the key wont turn my ignition again! Is there a reason why it will randomly lock up like this? Could it be that my mechanic messed with something and this is a result of that?
