Yes, a worn key can cause starting problems in a vehicle. If the key's teeth are too worn down, it may not engage the ignition cylinder properly, preventing the ignition system from recognizing the key. Additionally, if the key has a transponder chip and it becomes damaged or loses its programming, the vehicle may not start. Regularly inspecting and replacing worn keys can help avoid these issues.

You cannot get the key to turn and come out of the ignition?

Key or ignition tumbler is worn. If you cannot remove the key, then you will have to remove the tumbler assembly and replace it. If you can get the key out, then try a key that is not used very often. If it works, have a duplicate made of that key and destroy the other key with the problems.
