Hello my name is ***** ***** I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required.

Cant you get into the bed through the rear seats?

Customer: replied 2 months ago.
I already did and removed the hard covers and I even drilled holes in the plastic back cover the the tailgate to try to access the latch/lock to open the tailgate but still can't open the tailgate

Have you tried taking these panels off?

Customer: replied 2 months ago.
I can't take the back end panel off as there are bolt that are covered by the sides of the box. Until I can open the tailgate I can't unscrew the bolts holding it in hence I need to open the tailgate first

you may be able to lift the handle and access the rods that way with a screw driver and activate them and pop it

Customer: replied 2 months ago.
Tried but no luck. I can't get the rods to move. I'm guessing the lock prevents this.
