The key fob is designed to be durable and long-lasting, just like your Jeep. It’s built to withstand the demands of everyday use and the rugged adventures you take your Grand Cherokee on. However, like any device, it relies on a battery to function properly.

Choosing the Right Battery for Your 2012 Key Fob
Your key fob is an essential component of your Jeep Grand Cherokee, providing convenience and security. To ensure its optimal functionality, it’s important to choose the right battery when it comes time for a replacement.
The Recommended Battery Type
The key fob in your Jeep Grand Cherokee utilizes a CR2032 battery. This specific battery type is a 3V lithium battery, known for its reliability and longevity. You can easily find CR2032 batteries in most stores that sell batteries, and well-known brands such as Duracell and Energizer are trusted choices.
The Pitfalls of Substituting Batteries
While it may be tempting to use a different battery as a substitute, there are a few problems that can arise from doing so. Here’s why it’s best to stick with the CR2032 battery:
- Shorter Lifespan: Substituting a different battery might not provide the same lifespan as the CR2032 battery designed for your key fob. It’s always better to opt for the recommended battery to ensure long-lasting performance.

A Guide to Replacing Your Grand Cherokee Key Fob Battery
Replacing the battery in your Jeep Grand Cherokee key fob is a simple process that can help ensure the smooth functioning of your vehicle. Let me guide you through the steps:
Required Items:
- Jeep Grand Cherokee key fob
- CR2032 battery
- Small flat head screwdriver (optional)
Step 1: Release the Interior Key Your key fob has a small mechanical latch on its exterior. Slide it to release the interior emergency key. If you have an older key fob without an interior key, you can skip this step. In that case, you’ll need to use the screwdriver to pry the case apart.
Step 2: Open the Fob Now, take the key you removed and insert it into the emergency key slot. Gently twist the key to pry the fob case pieces apart and separate them. Be careful not to damage any internal components.
Step 3: Remove the Old Battery Once you’ve opened the fob, you’ll see the old battery. You can easily remove it with your nails or use the optional screwdriver if necessary. Take care not to damage the battery or any other parts of the fob.
Step 4: Insert the New Battery It’s time to insert the new CR2032 battery into the fob. Ensure that the positive (+) pole is facing down in the fob, which means you should not see the “+” sign when you insert the battery.
Step 5: Reassemble the Fob After inserting the new battery, snap the fob case pieces shut. Make sure they fit together properly and are securely closed. Take a moment to ensure that the new battery is firmly in place.
Step 6: Replace the Interior Key Finally, reinsert the interior emergency key into the fob. Ensure that it is correctly aligned and fits snugly.
Once you’ve successfully completed these steps, your key fob should be ready to use. It’s a good idea to test the fob to ensure it’s working properly. If you encounter any issues, you can repeat the process and confirm that the battery is correctly inserted with the positive pole facing down.
Remember, it’s important to store any extra batteries in a clean, dry place, out of the reach of small children. Properly disposing of old key fob batteries is also crucial to protect the environment.
Troubleshooting Key Fob Battery Issues
Hey there, fellow 2012 Jeep Grand Cherokee owner! I understand the importance of a fully functional key fob. It’s our ticket to convenience and security. But what do you do when you encounter issues with your key fob battery? Don’t worry, I’ve got your back. Let’s troubleshoot some common key fob battery issues together.
Dead Battery – The Most Common Issue
The most common culprit behind a malfunctioning key fob is a dead battery. It happens to the best of us. The solution? Replace the battery. You’ll need a new CR2032 battery, which you can find at most stores selling batteries or online. Remember, it’s always a good idea to keep spare batteries on hand for emergencies.
Checking and Fixing Metal Contacts and Corrosion
Sometimes, the metal contacts inside your key fob can get bent out of position or corroded, leading to intermittent detection issues. If you suspect this is the case, here’s what you can do:
- Open your key fob: Refer to the earlier section of this guide (Step 2: Open the Fob) for instructions on opening your key fob. Take care not to damage any internal components while doing so.
- Inspect the metal contacts: Once you have the key fob open, examine the metal contacts. If they appear bent or corroded, you can try gently adjusting them using a small flat head screwdriver. Be cautious to avoid further damage.
- Clean the contacts: If there’s corrosion on the metal contacts, you can use a Q-tip dipped in acetone or rubbing alcohol to gently clean them. This can help restore proper contact and improve the key fob’s functionality.
Broken Solder Joints – A Possible Cause
In some cases, the solder joints connecting the electronic components of the key fob can become damaged or broken. If you’re comfortable with soldering, you may attempt to re-solder these joints to fix the issue. However, if you’re unsure or inexperienced, it’s best to seek assistance from a professional who can safely perform the repair.
Radio Interference or Signal Jammers – A Potential Disruptor
Occasionally, your key fob may face issues due to external factors such as radio interference or signal jammers. While this is less common, it’s worth considering. Here’s what you can do:
- Listen for the locking sound: When you click your key fob’s buttons, pay attention to whether you hear the “locking sound” indicating that your car is receiving the signal. If you don’t hear the sound, it could indicate radio interference or signal jamming.
- Move to a different location: If you suspect radio interference or signal jamming, try moving to a different location away from potential sources of interference. This could include areas with strong radio waves or buildings that might block the signal.
Using the Correct Key Fob
It may seem obvious, but using the correct key fob for your Jeep Grand Cherokee is essential. If you have multiple key fobs, make sure you’re using the one specifically programmed for your vehicle. Using the wrong key fob can lead to compatibility issues and improper functioning.
When in Doubt, Consult a Professional
If you’ve tried the troubleshooting steps mentioned above and your key fob battery issue persists, or if you’re unsure about performing any repairs yourself, it’s always best to consult a professional. They have the expertise to diagnose the problem accurately and provide appropriate solutions. Don’t hesitate to reach out to a trusted locksmith or your local Jeep dealership for assistance.
I hope these troubleshooting tips help you get your key fob back
