Modern Chrysler vehicles come equipped with key fobs that offer unparalleled convenience, from remote unlocking to starting your car. However, like any electronic device, the battery in your Chrysler key fob will eventually need replacing. Recognizing the signs of a weakening battery and knowing how to replace it yourself can save you time and money. This guide will walk you through the simple process of replacing the battery in your Chrysler key fob, ensuring you can maintain the seamless functionality you rely on.
Recognizing the Signs of a Dying Key Fob Battery
Before your Chrysler key fob completely stops working, it will usually give you some warning signs that the battery is getting weak. Being aware of these signs can help you proactively replace the battery before you’re stranded or inconvenienced.
One of the primary indicators is a decrease in range. You might notice that you need to be significantly closer to your Chrysler vehicle for the key fob to lock or unlock the doors. Where you used to be able to activate the remote from a distance, you now have to be right next to the car.
Another common symptom is inconsistent operation. You might press the buttons on your key fob and sometimes nothing happens. It could take multiple attempts to get your Chrysler to respond, whether you’re trying to unlock the doors, open the trunk, or activate the panic alarm. In some cases, certain functions might become unreliable while others still work intermittently.
While less common, some Chrysler models may display a warning message on the dashboard indicating a low key fob battery. Check your vehicle’s owner’s manual to see if this feature is available for your specific Chrysler model. If you see such a warning, replacing the battery should be a priority.

Gathering Your Tools and Materials
Replacing the battery in your Chrysler key fob is a straightforward DIY task that requires minimal tools and materials. Here’s what you’ll need to get the job done quickly and efficiently:
- A New Battery: The most crucial item is the replacement battery. Chrysler key fobs typically use a CR2032 3V lithium coin cell battery. However, always verify the specific battery type required for your key fob by checking your owner’s manual or by examining the old battery once you open the fob. Using the correct battery type ensures proper function and longevity.
- A Small Flat-Head Screwdriver or Pry Tool: You’ll need a tool to gently open the key fob casing. A small flat-head screwdriver works well, but be careful not to use excessive force to avoid damaging the plastic. Alternatively, you can use a plastic pry tool designed for electronics or even a thin coin, which can sometimes be less likely to scratch the fob casing.
- Soft Cloth or Microfiber Cloth (Optional): Having a soft cloth on hand can be helpful to protect the key fob from scratches during the opening process and to wipe away any fingerprints or dirt after you’ve replaced the battery.
Step-by-Step Guide to Chrysler Key Fob Battery Replacement
With your tools and new battery ready, follow these simple steps to replace the battery in your Chrysler key fob:
Step 1: Open the Key Fob Casing
Carefully examine your Chrysler key fob to locate the seam or notch designed for opening it. This is usually a small slit or indentation along the edge of the fob.
Using your small flat-head screwdriver or pry tool, gently insert the tip into the seam. Apply slight twisting pressure to begin separating the two halves of the key fob. Work your way around the seam, gently prying until the casing starts to open. Avoid using excessive force, as this could damage the plastic clips that hold the fob together. Take your time and be patient.
Some Chrysler key fobs might have a small release button or latch that needs to be pressed or slid before you can pry the casing open. Refer to your owner’s manual if you are unsure about the specific opening mechanism for your key fob model.

Step 2: Remove the Old Battery
Once the key fob casing is open, you will see the old battery inside. Take note of the battery’s orientation before removing it. Usually, the positive (+) side of the battery will be facing upwards. This is important to ensure you install the new battery correctly.
Gently pry the old battery out of its holder. You can use your fingertip or the edge of your small screwdriver to carefully lift the battery out. Be mindful not to damage the battery contacts or any other components inside the key fob.
Properly dispose of the old battery according to your local regulations for battery disposal. Many communities have designated collection sites for used batteries.

Step 3: Install the New Battery
Take your new CR2032 battery and insert it into the battery holder in the same orientation as the old one you removed. Ensure the positive (+) side is facing upwards if that was the original orientation.
Press down firmly but gently on the new battery to ensure it is securely seated in the holder and makes good contact with the terminals. You should feel a slight click or resistance as it snaps into place.
Step 4: Reassemble the Key Fob
Carefully align the two halves of the key fob casing. Press them firmly together until they snap back into place. Ensure that the casing is completely closed and there are no gaps. You should hear a clicking sound as the clips re-engage.
Once reassembled, test your Chrysler key fob to ensure it is working correctly. Try locking and unlocking your doors remotely, and test any other functions your key fob offers, such as remote start or trunk release.
Troubleshooting and Tips
- Key Fob Difficult to Open: If you are having trouble opening the key fob, double-check for any release buttons or latches. Apply gentle but consistent pressure when prying, and try working around the seam slowly. Avoid forcing it, which could break the plastic.
- Key Fob Still Not Working: If your key fob still doesn’t work after replacing the battery, double-check that you installed the new battery with the correct polarity (+ side up). Ensure the battery is the correct type (CR2032) and is brand new. If problems persist, there might be an issue beyond the battery, and professional assistance may be needed.
- Battery Disposal: Remember to dispose of old batteries responsibly. Do not throw them in the regular trash. Recycle them at designated battery recycling locations.
When to Seek Professional Help
While replacing a Chrysler key fob battery is usually a simple process, there are situations where seeking professional help is advisable.
If you are uncomfortable performing the battery replacement yourself or are worried about damaging your key fob, don’t hesitate to visit your local Chrysler dealership or a qualified automotive locksmith. They have experience with key fobs and can replace the battery for you quickly and efficiently.
Additionally, if you experience persistent issues with your key fob even after replacing the battery, there might be a more complex problem, such as a malfunctioning key fob or an issue with your vehicle’s receiver. In these cases, professional diagnosis and repair are necessary.
Replacing your Chrysler key fob battery is a routine maintenance task that can keep your remote access features working reliably. By following these easy steps, you can confidently replace the battery yourself and avoid unnecessary trips to the dealership. Enjoy the continued convenience of your Chrysler key fob!
