How to Change Battery in Chrysler Key Fob

Changing the battery in your Chrysler key fob is a quick and easy process that can save you the hassle and expense of a trip to the dealership. This guide will walk you through the steps involved, so you can get back to driving with a fully functional key fob in no time.

Understanding Your Chrysler Key Fob

Chrysler key fobs, like those for most modern vehicles, are powered by small batteries that eventually wear out. Knowing how to identify the signs of a dying battery and how to replace it is essential for every Chrysler owner. Common signs include decreased remote range, needing to push the button multiple times for it to register, or the key fob not working at all. Ignoring these signs can eventually leave you stranded, so proactive maintenance is key.

Identifying the Correct Battery Type

Before you start, you’ll need to determine the correct battery type for your specific Chrysler key fob. Most commonly, Chrysler key fobs use a CR2032 3-volt lithium battery. This information can typically be found in your owner’s manual. You can also look up the battery type online by searching for your specific Chrysler model year and key fob type.

Gathering the Necessary Tools

Fortunately, changing the battery in a Chrysler key fob doesn’t require any specialized tools. Most models can be opened using a flathead screwdriver or even a coin. Having a small plastic pry tool can also be helpful for avoiding scratches on your key fob. Make sure you have a fresh CR2032 battery ready before beginning the process.

Step-by-Step Guide to Changing Your Chrysler Key Fob Battery

Here’s a step-by-step guide to help you change the battery in your Chrysler key fob:

Locate the release notch: Carefully examine your key fob for a small notch or slot. This is usually located on the side or back of the fob.
Insert the flathead screwdriver or pry tool: Gently insert the flathead screwdriver or pry tool into the release notch and apply gentle pressure to separate the two halves of the key fob casing. Be careful not to force it, as this could damage the key fob.
Separate the key fob halves: Once the latch is released, carefully separate the two halves of the key fob. The internal components, including the battery, should now be visible.
Remove the old battery: Locate the old battery and gently pry it out of its compartment. You can use your fingernail or the flathead screwdriver to do this.

Insert the new battery: Insert the new CR2032 battery into the compartment, making sure the positive (+) side is facing up, just like the old battery.
Reassemble the key fob: Align the two halves of the key fob and press them together firmly until they snap back into place.
Test the key fob: Try all the buttons on your key fob to ensure it’s working correctly.

Troubleshooting Common Issues

If you’re still experiencing issues after changing the battery, here are a few troubleshooting tips:

Check the battery orientation: Ensure the new battery is inserted correctly with the positive (+) side facing up.
Try a different battery: Occasionally, new batteries can be faulty. Try a different battery to rule out this possibility.
Inspect the key fob for damage: Check for any physical damage to the key fob, such as cracks or broken components.
