Experiencing issues with your 2016 Dodge Challenger key fob? A common culprit, and often the easiest to fix, is a dead or dying key fob battery. While modern key fobs are designed for longevity, the battery will eventually need replacing. This guide will walk you through troubleshooting common key fob battery problems and provide steps for replacement, as well as explore other potential, less frequent issues that might mimic a battery problem.
Common Symptoms of a Low 2016 Dodge Challenger Key Fob Battery
Before assuming a more complex issue, it’s important to recognize the typical signs of a weak key fob battery. These can include:
- Reduced Range: You need to be closer to your Challenger than usual for the key fob to lock, unlock, or start the vehicle remotely.
- Intermittent Functionality: The key fob works sometimes but not others, requiring multiple button presses to achieve the desired action.
- Dashboard Warning Light: Some Dodge Challengers may display a “Low Key Fob Battery” warning message on the dashboard.
- No Response: In the most severe cases, the key fob might become completely unresponsive, failing to lock, unlock, or start the car remotely. You may need to use the physical key inside the fob to unlock your door.
If you are encountering any of these symptoms with your 2016 Dodge Challenger key fob, replacing the battery is the first and simplest troubleshooting step.
Replacing the 2016 Dodge Challenger Key Fob Battery: A Step-by-Step Guide
Replacing the battery in your 2016 Dodge Challenger key fob is a straightforward process that you can typically do yourself in a few minutes with minimal tools. Here’s a general guide:
- Identify the Battery Type: The 2016 Dodge Challenger key fob typically uses a CR2032 battery. Double-check your owner’s manual or the markings inside your key fob to confirm the correct battery type.
- Gather Your Tools: You’ll likely need a small flathead screwdriver or a similar thin tool to open the key fob casing. You’ll also need a new CR2032 battery.
- Locate the Notch: Examine your key fob for a small notch or seam. This is usually located on the side or bottom of the fob.
- Open the Key Fob Casing: Carefully insert the flathead screwdriver into the notch and gently twist to pry the key fob casing open. Avoid using excessive force, as you could damage the plastic casing.
- Remove the Old Battery: Once the casing is open, you’ll see the battery. Take note of the battery’s orientation (+ side up or down) before removing it. You may be able to gently pry it out with your fingertip or the flathead screwdriver.
- Insert the New Battery: Install the new CR2032 battery, ensuring it’s placed in the correct orientation as the old one.
- Close the Key Fob Casing: Carefully snap the two halves of the key fob casing back together until they are securely closed.
- Test Your Key Fob: Test the key fob’s functionality by attempting to lock and unlock your Dodge Challenger remotely.

Exploring Other Potential Key Fob Issues Beyond the Battery
If you’ve replaced the battery in your 2016 Dodge Challenger key fob and are still experiencing problems, the issue might be something other than a low battery. While less common, these possibilities include:
- Key Fob Antenna Issues: As mentioned in the original article, an antenna problem could affect the key fob’s signal reception. The antenna in your vehicle receives the signal from your key fob to unlock doors, start the engine remotely, etc. If there’s a poor connection, corrosion, or damage to this antenna, it could weaken the signal and cause key fob malfunctions. The original article suggests a potential connection issue in the antenna wiring, drawing an analogy to a radio antenna problem.
- Key Fob Damage: Physical damage to the key fob, such as from dropping it or exposure to moisture, could damage internal components and lead to malfunction.
- Vehicle Receiver Issues: In rare cases, the problem might not be with the key fob itself but with the receiver in your 2016 Dodge Challenger that picks up the key fob signal.
- Signal Interference: Strong radio frequencies or electronic interference in certain environments can sometimes temporarily disrupt key fob signals.

Troubleshooting Antenna Issues (and When to Seek Professional Help)
Diagnosing and repairing antenna issues in your 2016 Dodge Challenger is generally more complex than a battery replacement and often requires specialized knowledge and tools. While the original article mentions a DIY fix for a radio antenna connection, accessing and troubleshooting the key fob antenna system might not be as straightforward.
If you suspect an antenna problem after ruling out the key fob battery, it’s recommended to:
- Consult Your Owner’s Manual: Your owner’s manual may provide information about the location of the key fob antenna or any troubleshooting steps you can safely perform.
- Contact a Qualified Mechanic: The most reliable course of action is to take your 2016 Dodge Challenger to a certified mechanic or dealership service center. They have the expertise and equipment to diagnose the issue accurately and perform any necessary repairs to the antenna system or other related components.
Attempting to access or repair vehicle antenna systems without proper knowledge can potentially cause further damage. For antenna-related or more complex key fob issues, professional assistance is highly recommended.
Conclusion
While a dead battery is the most frequent cause of 2016 Dodge Challenger key fob problems, understanding other possibilities, such as antenna issues, is helpful for effective troubleshooting. Start with the simple and cost-effective battery replacement. If the problem persists, consider the less common scenarios and seek professional help to ensure proper diagnosis and repair of your key fob system. Keeping your key fob functioning reliably is crucial for the convenience and security of your 2016 Dodge Challenger.
