A dead key fob battery can be a major inconvenience, especially when you’re in a hurry. If your Chrysler key fob is acting up, a dead battery might be the culprit. Fortunately, replacing a Chrysler key fob battery is a quick and easy process that you can do yourself. This comprehensive guide will walk you through everything you need to know about Chrysler key fob batteries, from identifying the signs of a dying battery to replacing it yourself.
How to Tell if Your Chrysler Key Fob Battery is Dying
Your Chrysler key fob relies on a small battery to send signals to your car. Over time, this battery will naturally drain and eventually die. Recognizing the signs of a dying battery can save you time and frustration. Here are a few telltale signs:
- Decreased range: You may notice that you need to be closer to your car for the key fob to work.
- Intermittent functionality: The key fob may work sometimes and not others, or you may experience lag when using it.
- Dashboard warning: Some Chrysler models will display a “Key Fob Battery Low” warning message on the dashboard.
- Key fob buttons require multiple presses: If you find yourself pressing the buttons harder or multiple times to get a response, it’s a clear indication of a weakening battery.
What Battery Does a Chrysler Key Fob Take?
Most Chrysler key fobs use a CR2032 battery, a common type of lithium coin battery. You can find these batteries at most hardware stores, auto parts stores, and online retailers.
Tools You Need to Replace the Battery
Before you begin the replacement process, gather the following tools:
- A small flat-head screwdriver or a plastic pry tool
- A new CR2032 battery
How to Change a Chrysler Key Fob Battery: A Step-by-Step Guide
Replacing the battery in your Chrysler key fob is a straightforward process. Here’s a step-by-step guide:
- Locate the key slot: Look for a small slot on the back or side of your key fob.
- Open the key fob: Insert the tip of the flat-head screwdriver or the plastic pry tool into the key slot and gently pry open the key fob casing. You may hear a slight click when the casing separates.
- Identify and remove the old battery: Carefully remove the old battery from its compartment. Avoid using metal tools for this step, as they can damage the battery or the key fob.
- Insert the new battery: Place the new CR2032 battery into the compartment with the positive (+) side facing up.
- Reassemble the key fob: Align the two halves of the key fob casing and press them together until they snap back into place.
Tips and Precautions
- Handle the battery with care: Avoid touching the flat surfaces of the new battery, as this can reduce its lifespan.
- Dispose of the old battery properly: Lithium batteries should be recycled according to your local regulations.
- Don’t force the key fob open: If you’re having trouble opening the key fob, consult your owner’s manual or look for a tutorial specific to your Chrysler model online.
Programming Your Chrysler Key Fob After Battery Replacement
In most cases, your Chrysler key fob should automatically resync with your vehicle after a battery replacement. However, if you’re experiencing issues, you may need to reprogram it manually. Refer to your owner’s manual for specific instructions on how to program your key fob.
Common Issues and Troubleshooting Tips
While replacing the battery is usually a simple fix, you might encounter a few hiccups. Here are some common issues and troubleshooting tips:
- Key fob still not working after battery replacement: Ensure that you’ve installed the new battery correctly with the positive (+) side facing up. If the issue persists, there might be a problem with the key fob itself, and you may need to contact a Chrysler dealership or a qualified automotive locksmith.
- Key fob works intermittently: Check for any dirt or debris inside the key fob casing that might be interfering with the battery connection. Clean the contacts with a cotton swab and rubbing alcohol if necessary.
- Key fob buttons are unresponsive or sticking: Over time, the rubber buttons on your key fob can wear down or accumulate dirt, preventing them from making proper contact. You can try cleaning the buttons with a damp cloth and mild soap. If the problem persists, you may need to replace the key fob case or the entire key fob.
