Stuck/Frozen spare tire locking mechanism (2003 Supercrew Cab 4x4)
 

Hello all, I need a bit of help. The spare tire mechanism has frozen up from what I'm assuming is ice, and I can't get the spare tire down to change a flat. I've tried using 2 different keys (The original one for the truck, and one from my 02 f150 standard cab), none of which will lock into the mechanism and release the spare. Any help would be appreciated.

If it's frozen, put a heat gun or hair dryer on it and thaw it.
