On locking your keys in the vehicle. I did this last year about 20 miles from anything. This is what I did. I had an axe in the back of the pickup, so I cut a small tree down and fashioned a wedge out of it. Done a little finishing work on it with my pocketknife. Ended up making two of them. I drove the wedge in between the door and door frame in the top back of door. Used the blade of the axe to get a small space to start the wooden wedges. Once I had a gap created, I cut a small sucker off a maple tree, long and skinny, and bent it into an arc. With this I was able to hit the door unlock. The pressure caused by the wedges won't allow the door to unlock until you remove them and release the tension. Door unlocked with no damage.
Interesting, I locked my keys in an 09 Tacoma a few years ago and used the antenna to hit the unlock button, tried it on both passenger and drivers side, would click but not unlock. Luckily the keys were laying in the front seat and had one of those stupid lock fobs on the key ring and I was able to bend the antenna enough to hit the button on the fob and then they unlocked. I think it was some feature of the truck that the unlock button wouldn't work with the keys in the vehicle but not in the ignition, but possibly if I hadn't had the door pried open it would have worked. Did do the same thing on the outfitters Dodge one time when a client locked the keys in it, and hitting the door unlock worked fine to unlock it while there was a wedge in the door.
