I installed an aftermarket remote start system with push button start and proximity fobs. I wired it through the evo-all wire for wire to the remote start except for the horn which I didn't want beeping multiple times everytime I disarmed with the aftermarket fob. My main issue is with remote starting, but I will explain the behaviors of the systme in case they all add up to one answer.
When I unlock with the aftermarket fob the Accessory function of the ignition turns on for about 2 seconds then unlocks the truck. As long as the doors are all closed it will lock instantly, but the dome light takes about a minute to fade out. These I can live with. Usually I can hold the remote start button on my aftermarket fob for 4-5 seconds and it starts up no problem. At least once a week, sometime more frequently lately, the factory alarm will start sounding. If I start pressing keys randomly on the fob it may stop the alarm and then start, but usually it keeps sounding until I manually disarm the factory alarm. Luckily I have the keypad on the door to disarm the factory alarm since I don't carry the original keys anymore in lieu of the new push button start. The push button start works flawlessly everytime.
My Evo-All is updated to the newest firmware. I had it updated to the "Recommended" firmware, but something wasn't working correctly (can't remember exactly what, maybe the remote start, its been about 6 months).
Any help diagnosing this would be awesome. I love the remote start and the push button. But its really embarrasing trying to start the truck coming out of the store and then have your alarm sound until you walk accross the lot to enter code in door keypad. Takes away some of the conveniences.
