Replacing the 2009 Jeep Grand Cherokee Key Fob Battery: A Step-by-Step Guide
Replacing the key fob battery is a simple process that can be done at home. Here’s a step-by-step guide:
- Locate the release button: Look for a small button or notch on the key fob. This is typically located near the key ring or on the side of the fob.
- Separate the key fob halves: Press the release button and gently separate the two halves of the key fob casing. You may need a small flathead screwdriver to assist with this.
- Identify the battery: The CR2032 battery will be clearly visible inside the key fob.
- Remove the old battery: Carefully pry out the old battery using a small flathead screwdriver or your fingernail. Avoid damaging the battery contacts.

Troubleshooting Common Key Fob Issues
Sometimes, even with a new battery, your key fob might not work correctly. Here are some common issues and how to address them:
- Key fob not working at all: Check the battery installation. Ensure the battery is correctly placed and the contacts are clean.
