One way to get in, is to remove the license plate from the trunk. Draw a line between the bottom two license plate screw holes. Find the middle of that line. From there measure up one inch. Drill a 1/2 inch hole. Be careful not to drill into the latch. You just want to drill through the truck sheet metal. Use a thin straight slot screwdriver, move the latch to the right. Now go to your local hardware store and buy a 1/2 " plastic plug, paint it and plug the hole. Put your plate back on and no one will see it until you sell the car. Now you can get in your truck the next time you lock your keys in the trunk.
