Modern Chrysler vehicles come equipped with key fobs for convenient remote access and operation. These fobs, while incredibly useful, rely on batteries that need replacement from time to time. Is your Chrysler key fob acting up? A dying battery is often the culprit. This guide will walk you through the straightforward process of how to change the battery in your Chrysler key fob, saving you time and potentially money.
Recognizing When to Replace Your Chrysler Key Fob Battery
Just like any battery-powered device, your Chrysler key fob will show signs when its battery is getting weak. Being aware of these symptoms can help you proactively change the battery and avoid being caught off guard.
One of the primary indicators is a decrease in operating range. You might notice that you need to be much closer to your Chrysler vehicle for the key fob to lock, unlock, or start the engine remotely. Where you used to be able to activate functions from a distance, you now have to be right next to the car.
Another common sign is inconsistent operation. You may press the buttons on your Chrysler key fob and nothing happens, or it might take multiple presses for the command to register. This erratic behavior suggests that the battery is struggling to provide consistent power. In some cases, certain functions might stop working altogether, while others still function intermittently.
Gather the Right Tools and Battery for Chrysler Key Fob Battery Change
The good news is that changing your Chrysler key fob battery is a DIY-friendly task that doesn’t require special tools or a trip to the dealership. You likely have everything you need at home already.
Here’s what you’ll need:
- A New Battery: The specific type of battery your Chrysler key fob requires will vary depending on the model and year of your vehicle. However, the most common battery is a CR2032 battery. Check your owner’s manual or the old battery itself to confirm the correct type before purchasing a replacement. It’s always a good idea to have a spare CR2032 battery at home, as they are used in many small electronic devices.
- A Small Flat-Head Screwdriver or Pry Tool: This tool will be used to gently open the key fob casing. A small eyeglass screwdriver or a plastic pry tool designed for electronics will work perfectly. Avoid using large or sharp tools that could damage the key fob.
Step-by-Step Guide to Change Battery in Chrysler Key Fob
Once you have gathered your tools and the correct replacement battery, you are ready to proceed with the battery replacement. Follow these simple steps to successfully change your Chrysler key fob battery:
-
Open the Chrysler Key Fob Casing: Carefully examine your key fob. You should see a small seam or notch where the two halves of the fob meet. Using your small flat-head screwdriver or pry tool, gently insert the tip into this seam. Apply a slight twisting or prying motion to separate the two halves of the key fob. Work your way around the seam slowly and patiently to avoid cracking or breaking the plastic casing. Some Chrysler key fobs might have a small release button or latch that needs to be pressed or slid before you can pry it open – consult your owner’s manual if you are unsure.
-
Access and Remove the Old Battery: Once the key fob is open, you will see the circuit board and the battery compartment. The old battery will be visible, usually held in place by small clips or a retaining mechanism. Take note of the orientation of the old battery – specifically which side is facing up (+ or -). Gently pry the old battery out of its compartment. You can use your fingertip or the flat-head screwdriver tip to carefully lift it out.
-
Insert the New CR2032 Battery: Take your new CR2032 battery and insert it into the battery compartment. Ensure that you are placing it in the same orientation as the old battery you just removed (positive side up or down, as noted earlier). Press down gently until the new battery is securely seated in the holder.
-
Reassemble the Chrysler Key Fob: Carefully align the two halves of the key fob casing back together. Press them firmly until they snap back into place. Ensure that the casing is completely closed and that there are no gaps. You should hear a click as the two halves securely join.
-
Test Your Chrysler Key Fob: After reassembly, test all the buttons on your Chrysler key fob to ensure they are working correctly. Try locking and unlocking your car remotely, activating the panic button, and remote starting (if your fob has this feature). If everything is functioning as expected, you have successfully changed the battery in your Chrysler key fob!
When to Seek Professional Help for Key Fob Battery Replacement
While changing a Chrysler key fob battery is generally an easy task, there might be situations where you encounter difficulties or prefer professional assistance.
If you are struggling to open the key fob casing, or if you are unsure about the correct battery type for your specific Chrysler model, it is always best to seek help from a professional.

They will have the expertise and tools to handle various key fob types and ensure the job is done correctly without damaging your key fob.
