I unlocked my truck this morning with the key FOB and then tried to open the lifgate and it seems to be still locked. I opened the hatch glass and checked the manual lock/unlock switch and it is in the unlock position. I can hear the lock/unlock actuator work with I press the unlock button on the key FOB but it still remains locked. How can I get the panel off to see what is going on when the door will not open. I did not see an access hole to manual open the door. I am at a loss here. Any help would be appreciated.
