I just installed a new battery and a new stereo system in my 06 SRT Coupe, and now the alarm will go off when I'm out of range i think, or it may go off a few minutes after I set the alarm, I can't figure out the rationale. I also had an issue with the guys at the shop giving me a reversed battery which I didn't notice until it sparked when I installed it, but i don't' think i shorted anything out since all the electronics work. I've tried resting the key fob by holding two buttons together, but don't get the tell tail honk. I also get the three honk tamper warning when I unlock the car. I'm just not locking up the car now, but it sits in a public condo garage so don't want to keep doing that. Any suggestions?
