Common Viper Remote Start Key Fob Issues and Solutions
Let’s explore some of the most frequent issues Viper key fob owners encounter and offer practical solutions:
1. Viper Remote Start Key Fob Not Working
Problem: Your Viper key fob fails to respond when you press any buttons.
Possible Causes & Solutions:
- Dead Battery: The most common culprit is a depleted key fob battery. Try replacing the battery with a fresh one. You can usually find the battery type in your owner’s manual or online.
- Programming Issues: Your key fob might have lost its programming. Consult your owner’s manual or the Viper website for instructions on reprogramming your key fob to your vehicle.

2. Viper Key Fob Reduced Range
Problem: Your remote start works only at very close distances to your vehicle.
Possible Causes & Solutions:
- Weak Key Fob Battery: A weak battery can significantly reduce the signal strength. Replace the battery as a first step.
