Chrysler Key Fob Won’t Work After Replacing Battery? Here’s What to Do.

You just replaced the battery in your Chrysler key fob, expecting it to spring back to life, but it’s completely unresponsive. Don’t panic! This is a common issue and can often be resolved with a few simple troubleshooting steps. This guide will walk you through the most common reasons why your Chrysler key fob won’t work after replacing the battery and how to get it working again.

Why Won’t My Chrysler Key Fob Work After Changing the Battery?

While it seems counterintuitive, sometimes a new battery isn’t enough to get your key fob working again. Here are some of the most common culprits:

• Improper Battery Installation: It’s easy to insert the battery incorrectly, even if you think you’ve got it right. Double-check the orientation of the positive (+) and negative (-) terminals on the battery and in the key fob compartment.
• Dead New Battery: Believe it or not, even brand-new batteries can be duds. Try inserting a different new battery to rule this out.
• Key Fob Programming Issues: In some cases, replacing the battery can disrupt the programming within the key fob. This means your car no longer recognizes the signal from the fob.
• Internal Key Fob Damage: There might be internal damage to the key fob’s circuitry, possibly from impact, water damage, or wear and tear.
• Receiver Module Problems: While less common, there could be an issue with your Chrysler’s keyless entry receiver module, which receives the signal from your key fob.

How to Fix a Chrysler Key Fob That Won’t Work After Battery Replacement

Here are some troubleshooting steps you can take before resorting to a dealership visit or an expensive repair:

1. Reseat the Battery: Open your key fob and remove the battery. Inspect the battery terminals and the contacts inside the key fob for any signs of dirt or corrosion. Clean them with a cotton swab and rubbing alcohol if necessary. Reinsert the battery, ensuring it’s correctly positioned according to the polarity markings.

2. Try a Different Battery: As mentioned earlier, even new batteries can be faulty. Try a different new battery from a reputable brand.

3. Reprogram the Key Fob Yourself: Many Chrysler vehicles allow you to reprogram your key fob at home without special tools. Consult your owner’s manual for the specific instructions for your model year.

4. Inspect the Key Fob: Check your key fob for any physical damage, like cracks, loose buttons, or signs of water exposure. Internal damage will likely require professional repair or replacement.

5. Check Your Chrysler’s Fuse Box: Your car has a fuse dedicated to the keyless entry system. If this fuse is blown, your key fob won’t work. Consult your owner’s manual to locate the correct fuse and inspect it for damage.

When to Seek Professional Help

If the troubleshooting steps above don’t resolve the issue, it’s best to seek help from a qualified automotive locksmith or your Chrysler dealership. They have the diagnostic equipment and expertise to identify and fix more complex problems, such as:

• Key Fob Internal Repair: If there’s internal damage, they may be able to repair the key fob, which is often a more affordable option than full replacement.

• Replacing the Key Fob: If your key fob is beyond repair, they can provide and program a new one for your Chrysler.

• Diagnosing Receiver Module Issues: A malfunctioning receiver module requires professional diagnosis and potentially replacement.
