The Dodge Ram 1500's remote start will not work if its battery needs replaced. Remove the plastic key fob cover and pop out the 3 volt battery and replace with the same voltage. Another common cause of remote start malfunction, centers around the vehicle's system detecting one or more of the components needed to fire the engine are not in working order. Your car will display a warning light if the car is not in park or one of the doors or the hood or trunk are open. If the car's battery is undercharged or the "check engine" light is on, the system will be disabled. Low fuel levels and an unlocked vehicle can also cause this.

My key fob wouldn't start my 2015 Ram 1500 Big Horn, and set off my engine light. So, I went out and disconnected the positive post for 30 second and reconnected the post and it reset everything. Now it works fine!! FOR NOW

The battery on the key fob is likely dead, or the connection for the key fob may have been lost.
