Your key fob is more than just a gadget; it’s the link that binds you to your Jeep. Crafted to withstand the test of time, it’s a sturdy little device.

Testing For a Low Battery in Your Key Fob
Hey, fellow Jeep Grand Cherokee enthusiast! Keeping an eye on your key fob battery is crucial. Imagine being stuck outside your ride or unable to fire up the engine because your key fob’s battery decided to call it quits. Not cool, right? So, let’s dive into the telltale signs of a low battery in your key fob.
Time to Change Your Key Fob Battery? Here’s What to Look For:
First off, if your key fob starts playing hard to get and only works when you’re up close and personal with your vehicle, it’s a pretty good sign that the battery is on its last legs.
Hey, if you find yourself playing thumb wars with your key fob, hitting that unlock button over and over before your ride gets the message, it’s probably time to check your battery.
And if your key fob’s acting all moody, working one minute and not the next, that’s another hint your battery might be ready to call it quits.
Finally, if your headlights aren’t giving you that usual flash when you click, or you’re not hearing any signal sound when you hit the button, it’s a pretty clear sign you need a new battery.
Just a heads up, it’s way easier to swap out that battery early instead of waiting for it to totally die on you. Trust me, you don’t want to deal with that hassle.
Picking the Right Battery for Your Key Fob
Your Jeep Grand Cherokee key fob requires a CR2032 battery. This 3V lithium battery is quite common and easily available at most battery retailers. Brands like Duracell or Energizer are often reliable options.
While some folks might try to use a different 3V battery that fits in the key fob, I wouldn’t recommend it. Here’s why:
- The substitute battery might not last as long.
- It could be a poor fit, leading to inconsistent contact.
So, stick with a CR2032 battery. They’re affordable and have a long shelf-life, even if left unused in your drawer.

I’ve got to say, these Duracell batteries are a game-changer. They’ve got this bitter coating that discourages kids from sticking them in their mouths. Always remember to keep your batteries stored safely and out of reach from children – they can be seriously harmful if swallowed.
The right battery is key (pun intended) to ensuring your key fob works like a charm, keeping your Jeep Grand Cherokee just a button press away.
Step-by-Step Guide to Changing Your Key Fob Battery
When it comes to my Jeep Grand Cherokee, having a properly functioning key fob is essential for convenience and security. So, let me walk you through a step-by-step guide on replacing your key fob battery.
You’ll need the following items:
- Key Fob
- CR2032 Battery
- Small Flat Head Screwdriver (optional)
Release the Interior Key: Your key fob has a small 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. Instead, use the screwdriver to pry the case apart gently.
Open the Fob: Take the key you removed and insert it into the emergency key slot. Twist it gently to separate and open the fob case pieces.
Remove the Old Battery: Once the fob is open, you can easily take out the old battery. If necessary, you can use the screwdriver to assist in removing it.
Insert the New Battery: Now, it’s time to insert the new battery. Make sure the “+” pole is facing downward inside the fob (you shouldn’t see the “+” sign).
Reassemble the Fob: Snap the fob case pieces shut after inserting the new battery.
Replace the Interior Key: Finally, put the interior emergency key back in its place.
Once you’ve successfully installed the new battery, test the fob to ensure it’s working correctly. If you encounter any issues, repeat the process and ensure the battery is securely in place with the positive pole facing down.
Remember to store any extra batteries in a clean, dry location, away from the reach of small children.
Troubleshooting Key Fob Battery Issues
As an owner myself, I’ve experienced various key fob issues. Let’s tackle them one by one:
Dead Battery: If your key fob isn’t working, the most common issue is a dead battery. Replacing the battery usually solves the problem. (Refer to the instructions above for battery replacement.)
Bent Metal Contacts: Sometimes, the problem lies with bent metal contacts inside the key fob, leading to intermittent detection issues. Use the instructions provided earlier to open the fob and check the contacts.
Corrosion: Check for corrosion, especially if water has entered the key fob. You can clean the corrosion using a Q-tip with acetone or alcohol.
Damaged Solder Joints: If you’ve replaced the battery, ensured there’s no corrosion, and the fob still doesn’t work, damaged solder joints might be the cause. In this case, you may need to resolder the joints if they are broken..
Radio Interference or Signal Jammers: Sometimes, radio interference or signal jammers can prevent your key fob from communicating with your Jeep. Listen for the “locking sound” when you click the key fob..
Wrong Key Fob: Ensure you’re using the correct key fob specifically designed for your Jeep Grand Cherokee.
If you ever feel uncertain or encounter persistent issues, it’s always wise to consult with a professional who can diagnose and fix the problem.
I hope these tips help you troubleshoot any key fob battery issues you might be facing. Drive safely!
Maintaining Your Key Fob and Battery

- Regularly Check Battery Life: Keep an eye on your key fob’s battery life. If you notice any slowdown in response or reduced range, it’s a sign that a battery change might be needed.
- Proper Storage: Store your key fob in a cool, dry place. Extreme temperatures can affect battery performance.
- Clean Your Key Fob: Over time, dust and debris can accumulate in the key fob, potentially affecting its function. Use a soft cloth for the exterior and a compressed air duster for the interior.
- Avoid Water Damage: Keep your key fob away from water as much as possible. If it gets wet accidentally, remove the battery and allow it to dry completely before reassembling.
- Handle with Care: Although key fobs are designed to be durable, they can still be damaged by drops or rough handling. Be mindful of how and where you store your key fob.

Protecting Your Key Fob with a Faraday Box
I’ve realized that taking care of my key fob is just as important as maintaining my vehicle. To ensure its safety, I’ve found a great solution: a Faraday box.
(Like many people, I keep my key near the front door, which means it’s vulnerable to being read through the wall, especially at night. If you don’t have a Faraday box or a trusty furry friend, make sure to keep your keys far away from the front door.)
The Faraday box, also known as a Faraday bag, is a protective container designed to block all radio signals, including those from your key fob. By placing my key fob in a Faraday box when it’s not in use, I can effectively prevent potential car thieves from intercepting the signal and gaining access to my vehicle.
Car theft techniques have evolved with advancing technology, and thieves can now exploit the transmitter signal of keyless car fobs. A Faraday box acts as a shield, effectively absorbing these signals and keeping my car safe.
Investing in a Faraday box for my key fob is a small price to pay for the peace of mind it brings. It’s a simple and highly effective way to enhance the security of my 2018 Jeep Cherokee.
