For some reason my ignition will not turn back when it is cold outside. I've only had this problem when it is cold outside. i have replaced the lock and cylinder already. Can someone please help me. Also the shifter locks when its put back in park.

 

If you cannot rotate the key to remove it, then most likely the shift cable is out of adjustment. Go here > http://techauto.awardspace.com/ignit...tch.html#stuck

 

Thank you I will give that a try.
