Hello and welcome to FixYa!

If it clicks then she's still ok. The lock may have been stuck that's why it won't open. As a first course of action, I strongly suggest that you spray WD40 on the mechanism. This will loosen the lock and will resolve the problem.
Hope this helps and thank you for using FixYa! Have a good one!

you can remove those bars to shut the gate BUT when you do theres nothing to hold gate from dropping all the way down to bumper. hope this helps!!!!

Open the tail gate, and you will see on the side of the tail light housing two screws that you will need to unscrew in order to take the housing out. If it is the tail light ,that is on the actual gate, open the tail gate and remove the plastic bed liner there are few of screws that need to be removed. Hope this helps you fix it.

You should be able to remove the trimpanel on the lift-gate. then at the location of the striker in the middle-bottom of lift-gate you should be able to access a rod. Grab the rod with pliers, if pliers won,t fit the rod connects to a metal lever attached to the striker assembly, pry the lever away from the striker and this should release you gate....Good Luck!!!

need to unscrew the main latch and reset

you need to remove the tail gate rear cover (i think it is a torx bit 30) and then manualy open the tail gate. more than likely it will need a handle, and two latches.
