If you still have the rear led i can work you through getting it to work. I found the technical manual for the remote start and now i have all leds in the interior and can open the door, put key in, everything(all the good settings) I can email you the tsb and help if you need it!
Hey there! Yeah believe it or not I removed the rear LED bulb and tried it again. Still nothing. I replaced it with the OE bulb and BINGO started right up. So when it beeped three times and didn't start it was code for door ajar, or dome light problem. Since I just put in the bulbs I figured that was the place to start. So I guess there is something with the OE bulbs completing the circuit for a door ajar/dome light connection for the remote start. So I left the front LED bulbs in and just deal with the crappy rear yellow bulb
