1999 Chevy Tahoe door latch

1999 Chevy Tahoe with cargo doors. The right door has a latch which goes over the left door. Somehow the latch got bumped and is in the closed position. Neither the auto door opener nor the key will let the latch come open. Any help?

Response:
1)Try to hold the handle open and pop the latch in the door with a screwdriver its happened to me once or twice
2)You may have to replace the latch I am guessing that it is jammed.
3)you carefully remove the lower panel by popping out the plastic tabs, usually done by inserting screwdriver between panel and door and prying. After removing the lower panel, peel back the plastic covering the metal door, and check the metal tab on the latch mechanism. If a bunch of dirt and needles are on the top of the door on the top weather stripping, I have seen this collection of dirt/debris prevent a functional latch mechanism from allowing the door to open.
