This could be caused by several things. First try lubricating the lock cylinder with WD40 and work it in with the key. Also use a new key. If these don't help, your park position switch may be failing which will keep the key stuck in the ignition. If this switch is also tested OK than the lock cylinder itself could very well need replacing.
