Hi : I have a key/lock issue that I was hoping someone could help me with: The 2010 I recently acquired has an ignition key, however this does not lock the tailgate. It fits into the lock but does not turn. So, the tailgate is always unlocked. There also is no key for the hard tonneau cover, which I have to open using the cable once I open up the tailgate. Is there a separate key for the tailgate and also another key for the tonneau cover? Anyone have any suggestions as to what my options are? Thank you!
