Trunk lock won't turn
 

About halfway through this winter my trunk lock stopped turning. Trunk opens fine with the release by the driver's seat but the key won't turn at all. Is there something I can spray in there to see if maybe some salt or something got in there and is causing it to stick? Could I just spray some WD-40 in there or on the key and put the key in?

Thanks {thumbup}

Not sure whats wrong with it but Im sure you could get a new one.
Try www.mitsubishiparts.net and see how much they want.Good luck.

I'd suggest some light oil right in the key hole.
