beerjet, If this truck is your daily driver just fix the door and call it done. Remote door latches can be a pain in the ### !!!
Lets think about this...
Scenario #1.... You take the family to the lake. Back the boat down the ramp. Everyone gets out. You walk back to unhook the boat. As the door closes behind you, you think wheres the remote (its on the keyring, in the running truck, that you cant get into).

Sure, you can add a "secret button" to pop the door open, and hope the thieves don't find it.
Scenario #2.... Your getting ready to go to work. You walk out to the truck, push the little button on your remote, and nothing happens

. Lets try this again, push the little button a little harder, still nothing. Well maybe the remote is broken. Good thing you were smart and had that "secret button" installed

. You push the "secret button" and nothing happens

. Due to an act of God, the trucks battery is dead, and you cant get in to open the hood. Or maybe the solenoid that pops the door is bad, or the relay, or the alarm brain, or a fuse, etc, etc, etc. Doesn't matter because there all inside the truck, and your not.
