I have an 07 and I'm having an issue with my rig not starting. It started with the radio glitching off an on and the red security light would come on while it happened. Fast forward to Monday, I got to work turned it off, pulled the key and it was still running. I had to pull a fuse to shut it off. I put the fuse back in and the door chime went off and the lights on the dash turned on like the was a key in the ignition. I disconnected the battery and went into work. I got off work and reconnected the battery and the same thing happened. I got it towed home and my buddy and I looked it over and decided it was the ignition switch. So I got a replacement (just the switch not locking cylinder). We installed the new switch and it started, with some weird issues such as everything briefly coming on when I unlocked the doors with the fob. I went inside and came out the next morning, got in my Jeep and the aftermarket alarm light was flickering, I disconnected the battery and reconnected it with the key in the ignition and it started fine. Went to work and noticed the red light was on again. Got to work and went inside. I came out the next morning and the same thing, everything was on with no key in the ignition. My buddy and I messed around with it to no avail. He was about to tow me home when I decided to turn the key and it randomly started, with the red light on again. I drove home, turned it off and it was once again running with no key in the ignition. Removed a fuse to shut it off and and the same thing, door chime and all the lights on the dash came on like there was a key in the ignition and the aftermarket alarm light was blinking. After troubleshooting we decided that maybe the alarm failed. We removed it, reconnected the battery and everything came on again. I should also mention that when it thinks there's a key in the ignition it doesn't even click when I do put a key in and try to turn it on. My battery is brand new, the alternator and the starter are only a year old. Any advice?
