As a Jeep owner, you rely on your key fob daily for seamless access and security. But have you ever wondered, “What Battery Does A Jeep Key Fob Take?” It’s a common question, and understanding the answer is crucial for maintaining your vehicle’s convenience. Like any battery-powered device, your Jeep key fob will eventually need a battery replacement. Recognizing the signs and knowing the right battery type will save you time and hassle. Let’s dive into the specifics to keep you confidently on the road.
Identifying the Right Battery for Your Jeep Key Fob
Generally, most Jeep key fobs are powered by a CR2032 battery. This is a 3V lithium coin cell battery that’s widely available and known for its longevity and reliability in small electronic devices. The CR2032 is a popular choice for key fobs across various car brands, including Jeep, due to its compact size and stable power output.

Why CR2032 is Commonly Used
The CR2032 battery strikes a good balance between size, power, and lifespan, making it ideal for key fobs. Its lithium chemistry ensures a relatively long shelf life and consistent performance, even under temperature variations. This is important for a device like a key fob that you need to rely on in all weather conditions. While CR2032 is the most common, it’s always a good idea to double-check.
How to Confirm the Battery Type
The most reliable way to confirm “what battery does your jeep key fob take” is to open your key fob and visually inspect the existing battery. Once opened, the battery type is usually printed directly on the battery itself. Look for markings like “CR2032,” “CR2025,” or similar codes. While CR2032 is the standard, some older or specific Jeep models might use a different type. Alternatively, your Jeep owner’s manual should specify the correct battery for your key fob model.
Signs Your Jeep Key Fob Battery Needs Replacing
Being proactive about your key fob battery can prevent unexpected lockouts or starting issues. Here are the common signs indicating it might be time for a replacement:
- Inconsistent Locking and Unlocking: If you find yourself pressing the lock or unlock button multiple times before your Jeep responds, it’s a strong indicator of a weakening battery. This is often the first and most noticeable sign.
- Reduced Operating Range: Key fobs are designed to work from a certain distance, typically up to 50 feet. As the battery weakens, this range diminishes. You might need to be much closer to your Jeep for the fob to function.
- Dashboard Warning Light: Some newer Jeep models feature a dashboard warning light or message that specifically indicates a low key fob battery. Pay attention to your instrument cluster for any such alerts.
- Key Fob Becomes Unresponsive: In the most severe cases, your key fob might become completely unresponsive. While this could also indicate other issues, a dead battery is the most likely culprit, especially if other signs were present beforehand.

Step-by-Step Guide: Jeep Key Fob Battery Replacement
Replacing the battery in your Jeep key fob is a straightforward process you can easily do yourself. Here’s how:
- Gather Your Tools and Battery: You’ll need a new CR2032 battery and a small flathead screwdriver or a similar prying tool.
- Open the Key Fob: Locate the small seam on your key fob casing. This is usually near the key ring attachment. Gently insert the flathead screwdriver into the seam and twist to carefully pry the fob open. Avoid excessive force to prevent damage.
- Access the Battery Compartment: Once open, you’ll see the circuit board and the battery compartment. The battery is usually easily accessible.
- Remove the Old Battery: Note the orientation of the old battery (usually the positive side facing up). Gently pry out the old CR2032 battery.
- Insert the New Battery: Install the new CR2032 battery in the same orientation as the old one. Ensure it’s securely seated in the compartment.
- Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together until they are firmly closed.
- Test Your Key Fob: Test the lock and unlock buttons to ensure the new battery is working correctly.
Programming (If Necessary)
In most cases, replacing the battery will not require reprogramming your Jeep key fob. However, if you experience issues after battery replacement, consult your Jeep owner’s manual for key fob programming instructions or visit your local Jeep dealership for assistance.
