Thanks i got it open . . . thats why i was locking it so it wouldnt get stolen i just got it 2 weeks ago i used to keep the tailgate locked on my 350 too....it was so tight to unlock it i was afraid i was going to break the key... locking it is very smooth but unlocking is still very tight im gunna try taking the panel out and cleaning it and put sum WD40 in there.
