I locked the keys in my Ranger last summer at midnight with a load of chairs. Thankfully the rear slider window on the cabv was open. Sadly, the slider on the front of thecap was not. Also, the slider on the cap can only be opened from the cab side. Fortunately I had tools in the box - unloaded all the chairs,unbolted the cap, moved it back onthe box and got in through the cab slider to get the keys out of the ignition - - - It was 2am by the time I got home.
