You probably have a known defective lock. There is a recall for the defective locks. As I recall the problem arises if you remove the key from the lock when it is in the 3 o'clock position. You must always return the key to the 12 o'clock position. There is a website where you can apply for a free replacement. Search this forum to find lots of posts on the issue.
