Why Your Jeep Cherokee Key Fob Battery Dies
Before diving into the replacement process, let’s understand why your key fob battery might be losing its charge.
- Battery Age: Like all batteries, key fob batteries have a limited lifespan. Over time, their ability to hold a charge decreases, leading to a sluggish or unresponsive fob.
- Frequent Use: The more you use your key fob, the more the battery gets drained. If you’re constantly locking and unlocking your Cherokee, you might be putting extra strain on the battery.
- Extreme Temperatures: Extreme heat or cold can significantly impact battery performance. Storing your key fob in a hot car or a freezing environment can shorten its lifespan.
Tools You’ll Need
Before you start, gather these simple tools:
- New CR2032 Battery: This is the standard battery used in most Jeep Cherokee key fobs.
- Small Screwdriver: A small flathead screwdriver is ideal for prying open the key fob.
- Optional: Tweezers: These can be helpful for removing the old battery, especially if it’s stuck.
Step-by-Step Guide to Changing Your Jeep Cherokee Key Fob Battery
1. Locate the Battery Compartment: Turn your key fob over. You’ll usually find a small, rectangular or circular latch or button on the back.
2. Open the Key Fob: Carefully use your screwdriver to pry open the latch or button. Be gentle to avoid damaging the key fob‘s casing.
3. Remove the Old Battery: Once the key fob is open, you’ll see the old battery. Remove it using your fingers or tweezers.
4. Insert the New Battery: Align the new CR2032 battery with the positive (+) and negative (-) terminals inside the key fob. The battery should slide in easily.
5. Close the Key Fob: Carefully snap the key fob back together. Ensure the latch or button is properly secured.
6. Test the Key Fob: Try using your key fob to unlock and lock your Jeep Cherokee. If it works, you’ve successfully replaced the battery.
Troubleshooting Tips
- Check the Battery Orientation: If the key fob isn’t working, double-check that the new battery is properly aligned with the positive and negative terminals.
- Try a Different Battery: If you’re still having problems, try using a different CR2032 battery to rule out a faulty new battery.
