Experiencing issues with your 2018 Jeep Renegade key fob can be frustrating. One of the most common culprits is a low or dead battery. If you’re finding your key fob is working intermittently or not at all, don’t immediately assume you need a new key fob or expensive reprogramming. The solution might be as simple as replacing the battery.
Common Signs of a Weak Key Fob Battery
Before you jump to conclusions about complex issues, consider these common symptoms that indicate a low 2018 Jeep Renegade Key Fob Battery:
- Reduced Range: You need to be closer to your Renegade than usual for the key fob to lock, unlock, or start the vehicle remotely.
- Intermittent Functionality: The buttons on your key fob work sometimes, but not consistently. You might press a button multiple times before it registers with your Jeep.
- Dashboard Warning Light: Some Jeep Renegade models may display a warning message on the dashboard indicating a low key fob battery.
- No Response: In the most obvious case, your key fob might completely stop working, failing to lock, unlock, or remotely start your vehicle.

Replacing Your 2018 Jeep Renegade Key Fob Battery: A DIY Approach
Replacing the battery in your 2018 Jeep Renegade key fob is generally a straightforward process you can do yourself, potentially saving you time and money compared to dealership service. You’ll typically need a small flathead screwdriver and a replacement CR2032 battery, which is widely available.
While specific steps can vary slightly depending on your exact key fob model, the general process involves:
- Locating the Notch: Look for a small notch or seam on the side of your key fob. This is usually where you’ll need to pry it open.
- Carefully Prying Open the Fob: Using the flathead screwdriver, gently insert it into the notch and twist to separate the two halves of the key fob. Be careful not to apply excessive force, as you could damage the casing.
- Identifying the Battery: Once open, you’ll see the battery compartment. Note the orientation of the old battery (+ side up or down) before removing it.
- Replacing the Battery: Remove the old battery and insert the new CR2032 battery in the same orientation.
- Reassembling the Fob: Carefully snap the two halves of the key fob back together until they are securely closed.
- Testing: Test the key fob buttons to ensure they are now working correctly.

When Battery Replacement Isn’t Enough
If you’ve replaced the 2018 Jeep Renegade key fob battery and are still experiencing issues, the problem might be more complex. Consider these other possibilities:
- Aftermarket Key Fobs: As the original article mentions, if you purchased your Renegade pre-owned, there’s a chance the key fob is an aftermarket replacement. While some aftermarket fobs work well, others can be unreliable or have shorter battery life. If you suspect an aftermarket fob, consider getting an OEM (Original Equipment Manufacturer) key fob from a Jeep dealer.
- Programming Issues: Sometimes, even with a new battery, the key fob may need to be reprogrammed to communicate properly with your Jeep. While some locksmiths offer programming services, the original article wisely suggests going to a Jeep dealership for programming, especially if you suspect the key fob itself might be the issue. Dealer programming ensures compatibility and can rule out any programming-related problems.
- Vehicle-Side Issues: In rare cases, the problem might not be the key fob at all, but rather an issue with your Jeep Renegade’s receiver or electrical system. If you’ve tried a new battery and even an OEM key fob programmed by a dealer, and the issues persist, it’s time to have your vehicle professionally diagnosed.
Seeking Professional Help
If troubleshooting the 2018 Jeep Renegade key fob battery and considering OEM fobs and reprogramming still doesn’t resolve your issue, it’s best to consult with a qualified mechanic or your Jeep dealership. They can perform a thorough diagnosis to pinpoint the exact cause of the problem and recommend the appropriate solution. While starting with the battery is a simple and cost-effective first step, don’t hesitate to seek expert help when needed to ensure your key fob and vehicle are functioning correctly.
