Starter not working (possible security issue)

Vehicle listed above Grand Cherokee blew out a tension-er, and replaced it, drove fine that night. I had to jump it the next morning and the alarm sounded and no start. Finally replaced the battery, and still no start unless I leave key in "on" position and bridge the starter bolts with a screwdriver, then it starts and runs fine. Pictured is the little security box with "panic" and "valet" buttons. I have tried a bunch of different key in door and ignition and combos thereof that I found, and no luck on a workaround. Cannot locate anything where everything says the module is supposed to be behind the glove box, but found one similar with only 6 pins under dash by the steering column. Also, issues with the cluster (no fuel gauge, oil and temperature are off and on, and usually follow accelerator when it first starts out).
