tailgate lock

I've been having trouble with my tailgate handle. The key lock seems to be stuck and won't turn with the key inserted. I've removed the access panel and manually unlocked the lever that was keeping my tailgate locked and unable to open with the handle so I can now open the tailgate normally...

Hey everyone, So i have a loaded up 2009 Ram Laramie and just recently put a bakflip G2 tonneou cover on it so i could lock and secure goods in the back. The problem i have now is there are no aftermarket tailgate locks for a 1500 Ram. The dealer can order all the factory parts "6 parts in all"...
