I've had mixed results with remote starters, factory installed one I LOVE! Aftermarket self installed or shop installed, nothing but problems. Got put into cuffs one night when driving home from the county fair in the 05 ram, the after market remote start tied into the headlight lights and brake lights, suddenly it malfunctions down a dark country road and I lost all lights and the truck shut off, with a County sheriff deputy right behind me. Nearly rearended the truck. Needless to say he wasn't happy. Put me in cuffs, sat me down until he finally listened to me and started trying to start the truck and turned the headlight switch. He let me go but made me tow it home. Found the remote starter box fried the next morning and ripped that sucker out
