The process of replacing the battery in your Chrysler key fob is straightforward and requires only a few simple tools.

Carefully open the key fob using a small flathead screwdriver or similar tool, ensuring not to damage the casing.

Once open, remove the old battery and insert the new one, paying attention to the correct polarity. Properly secure the casing back together, and test the key fob to ensure it’s functioning correctly. Regular maintenance like this ensures reliability and extends the lifespan of your key fob.

Replacing the battery proactively ensures the remote start, locking, and keyless entry functions work perfectly. This small maintenance task highlights a simple, actionable way to prolong the usability of your Chrysler’s key fob.

Step-by-Step Guide: How to Change Key Fob Battery Chrysler

Replacing your Chrysler key fob battery doesn’t require technical expertise. Follow these steps to complete the process effortlessly. Make sure you have a new battery ready, along with a small tool like a flathead screwdriver to open the fob.

Step 1: Confirm Your Chrysler Key Fob Battery Type

Before starting, locate the type and size of the battery your Chrysler key fob requires. Usually, this information is found in your car’s owner manual or printed on the back of the key fob itself.

Step 2: Inspect the Key Fob for Visible Screws or Access Points

Examine the edges of the key fob to identify how it opens. Some designs have visible screws, while others rely on snap-together fastening. If screws are present, use a precision screwdriver to loosen them. Understanding how the fob is held together helps prevent accidental damage during the process.

Step 3: Open the Key Fob Using the Correct Tool

For snap-together designs, use a flathead screwdriver or a similar thin, flat tool. Gently insert the tool into the seam or joint of the key fob casing and twist slightly to pop the halves apart. For screw-secured designs, carefully separate the casing after removing the screws.

Take note of the orientation of the battery and internal components as you open the fob. This step ensures easy reassembly later.

Step 4: Remove the Old Battery

Using your tool or fingernails, carefully lift the old battery out of its compartment. Be gentle to avoid damaging the battery holder or scratching any surrounding components. Once removed, properly dispose of the old battery according to local recycling guidelines.

Step 5: Insert the New Battery

Take your fresh CR2032 battery and align it correctly based on the polarity markings inside the battery slot. Usually, the positive (+) side of the battery should face up, but confirming with visual markings is essential.

Gently press the battery into the slot until it sits securely in place. Make sure the connection is firm for optimal functionality.

Step 6: Reassemble the Key Fob

Line up both halves of the key fob casing and snap them back together. For designs with screws, tighten them carefully without over-tightening, as excessive pressure may damage the casing.

Ensure every component—buttons, circuit board, and the battery itself—are properly seated before closing the structure entirely.

Step 7: Test the Key Fob

Once assembled, stand near your Chrysler vehicle and test the features of the key fob. Check its ability to lock, unlock, and start the car remotely. If it doesn’t respond, double-check if the battery is seated correctly and if the polarity aligns with the markings.

Step 8: Address Any Remaining Issues

If functionality hasn’t been restored, consider examining the key fob for dirt, grime, or internal corrosion. Rarely, additional issues may require professional assistance, in which case contacting a dealer or locksmith is recommended.

Step 9: Prepare for Future Maintenance

Finally, keep spare batteries handy, especially if your key fob features are critical to your daily life. Proactive preparation ensures you’re never caught off-guard by a non-functioning remote.

Step 10 (Optional): Reprogram the Key Fob if Necessary

While changing the battery typically doesn’t require reprogramming, some Chrysler models may need minor adjustments. Refer to your owner manual or contact a professional if you encounter paired-device errors after replacing the battery.

Common Key Fob Issues

Key fobs, while convenient, can occasionally encounter problems that disrupt their functionality. One of the most common issues is a depleted battery, which may cause the key fob to only work intermittently or stop working entirely. Physical damage, such as a cracked casing or worn-out buttons, can also impact performance. Signal interference from nearby devices or electronic systems might reduce the key fob’s range or prevent it from communicating with your vehicle.

Additionally, internal electronic malfunctions or software glitches could lead to unresponsiveness. To address these issues, regular maintenance, such as inspecting the key fob for damage and changing the battery promptly, can help ensure consistent operation. For complex problems, consulting a professional or contacting your vehicle’s manufacturer may be necessary.
