Is your Jeep key fob starting to act up? Are you finding yourself pressing the buttons multiple times to lock or unlock your doors, or noticing that you need to be much closer to your vehicle for the remote to work? These are common signs that your Jeep key fob battery is dying and needs replacing. Knowing the correct Jeep Key Fob Battery Size and how to replace it can save you time and a potentially unnecessary trip to the dealership.
Recognizing the Signs of a Weak Jeep Key Fob Battery
Before your key fob completely stops working, it usually gives you some warning signs. Being aware of these signals can help you proactively replace the battery and avoid getting locked out of your Jeep. Here are the two most common indicators:
- Multiple Attempts to Lock or Unlock: This is often the first and most noticeable sign. You press the lock or unlock button on your key fob, but your Jeep doesn’t respond immediately. You might need to press the button several times before the doors finally lock or unlock. This delay indicates that the signal from your key fob is weakening due to a low battery.
- Reduced Operating Range: A healthy Jeep key fob should work from a reasonable distance, typically up to 50 feet. As the battery weakens, this range significantly decreases. You’ll find that you need to be much closer to your Jeep, sometimes even right next to it, for the key fob to function. This limited range is a clear sign that the battery is losing power.
In optimal conditions, a Jeep key fob battery is designed to last for 3 to 4 years. If your key fob is exhibiting these symptoms and your battery is within or beyond this lifespan, it’s highly likely that a battery replacement is needed.
The Standard Jeep Key Fob Battery Size: CR2032
For most modern Jeep key fobs, the battery you’ll need is a CR2032 battery. This is a common 3V lithium coin cell battery that is widely available at most drugstores, grocery stores, hardware stores, and online retailers. It’s always a good idea to double-check your owner’s manual to confirm the exact battery type for your specific Jeep model and key fob, but the CR2032 is the standard Jeep key fob battery size for many models.
Step-by-Step Guide to Replacing Your Jeep Key Fob Battery
Replacing the battery in your Jeep key fob is a straightforward process that you can easily do at home in just a few minutes. Here’s a simple guide:
-
Gather Your Tools and Battery: You will need a small flathead screwdriver and a new CR2032 battery.
-
Open the Key Fob Casing: Locate the small seam on your Jeep key fob. This seam is usually near the keyring attachment. Use the flathead screwdriver to gently pry open the key fob at this seam. Be careful not to apply excessive force, as you could damage the casing.

Access the Battery: Once the key fob is open, you’ll see the circuit board and the battery compartment. The battery is usually easily accessible.
-
Remove the Old Battery: Take out the old CR2032 battery. Note the orientation of the battery before removing it – usually, the negative (-) side faces down. This will help you install the new battery correctly.
-
Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring it’s in the correct orientation (positive (+) side facing up, negative (-) side facing down, unless otherwise indicated in your specific fob).
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together until they are securely closed. You should hear a click indicating that it’s properly sealed.

Jeep Key Fob Programming (If Necessary)
In most cases, replacing the battery in your Jeep key fob will not require reprogramming. However, if you experience issues after replacing the battery, you may need to reprogram the key fob. Here’s a general programming procedure that might work for some Jeep models:
- Enter your Jeep and close all doors.
- Insert the key into the ignition and turn it to the “off” position.
- Open the driver’s side door and press the “lock” button on the door.
- Turn the ignition key to the “on” position and hold it for about five seconds.
- Remove the key from the ignition.
Refer to your Jeep owner’s manual for specific key fob programming instructions for your vehicle model, as procedures can vary.
