Keeping Your Jeep Cherokee Key Fob Running Smoothly
Your Jeep Cherokee key fob is a marvel of modern convenience, allowing you to lock, unlock, and even start your vehicle with the push of a button.

Don’t worry, changing the Jeep Cherokee key battery is a straightforward process that most owners can accomplish at home.
This comprehensive guide will cover everything you need to know, from identifying the correct Jeep Cherokee key fob battery type to safely opening the fob and installing the new power source.

Why Your Jeep Cherokee Key Fob Battery Needs Replacing
Over time, the constant use of your Jeep Cherokee key fob drains its internal battery. This is a natural part of its lifespan. You might notice a few symptoms indicating a dying battery:
- Reduced Range: The distance at which your fob can communicate with your Jeep Cherokee shortens significantly.
- Intermittent Functionality: The lock/unlock buttons might work sometimes but not others.
- No Response: The fob may completely stop working.
- Indicator Light Dim or Off: If your fob has an indicator light, a dim or unlit light is a strong indicator of a low battery.
Ignoring these signs can lead to frustration, especially when you’re in a hurry or dealing with inclement weather. Fortunately, a simple battery change is usually all that’s needed.
Identifying the Jeep Cherokee Key Fob Battery Type
The first crucial step in any Jeep Cherokee key fob battery replacement is knowing which battery your specific fob uses. While most Jeep Cherokee models utilize common coin-cell batteries, the exact type can vary depending on the year and model of your Cherokee.
Common Jeep Cherokee Key Fob Battery Types:
| Jeep Cherokee Model Year Range | Common Battery Type | Battery Voltage |
|---|---|---|
| 2014-2023 | CR2032 | 3V |
| Older Models (pre-2014) | CR2032, CR2016 | 3V |
- CR2032: This is the most prevalent battery for newer Jeep Cherokee key fobs. It’s a 3-volt lithium coin cell battery, commonly found in many electronic devices.
- CR2016: Some older Jeep Cherokee models might use this slightly thinner 3-volt lithium coin cell battery.
How to Confirm Your Jeep Cherokee Key Battery:
The most reliable way to determine your Jeep Cherokee key battery type is to:
- Check Your Owner’s Manual: Your Jeep Cherokee owner’s manual will explicitly state the correct battery type for your key fob. This is the definitive source of information.
- Examine the Old Battery: Once you’ve opened your key fob (as detailed in the next sections), the battery type and voltage will be printed on the old battery itself.
It’s always a good idea to have the correct replacement battery on hand before you start the process. Purchasing a reputable brand is recommended for longevity and performance.
Locating the Jeep Cherokee Key Battery and Opening the Fob
Most Jeep Cherokee key fobs are designed for easy access to the battery compartment. The Jeep Cherokee key battery location is typically within the main body of the fob. Here’s how to open most common Jeep Cherokee key fob designs:
For Key Fobs with a Removable Emergency Key:
Many Jeep Cherokee key fobs include a physical emergency key that can be detached. This is often the key to opening the fob.
Steps:
- Locate the Release Mechanism: On the side or back of your key fob, you’ll usually find a small sliding switch or button. This is the emergency key release.
- Slide or Press the Release: Hold down the release mechanism and simultaneously pull the metal key blade away from the fob.
- Expose the Seam: With the emergency key removed, you’ll see a small seam or slot along the edge of the key fob’s casing. This is where you’ll pry it open.
- Insert a Prying Tool: Use a small, flathead screwdriver, a plastic pry tool, or even a sturdy fingernail. Carefully insert the tool into the seam.
- Gently Pry Apart: Work your way around the seam, gently applying pressure to separate the two halves of the key fob. Avoid using excessive force, as this could damage the plastic. You might hear small clicks as the tabs holding the fob together release.
- Reveal the Battery: Once the fob is open, you’ll see the circular coin cell battery nestled within its compartment.
For Key Fobs Without a Removable Emergency Key:
Some Jeep Cherokee key fobs might not have an easily removable emergency key. These often have a small slot designed for prying.
Steps:
- Locate the Seam/Slot: Inspect the edges of your key fob. You’ll likely find a very thin seam running around the perimeter, or a specific notch or slot designed for prying.
- Insert a Prying Tool: Carefully insert a slim, flathead screwdriver or a plastic pry tool into the seam or slot.
- Twist or Lever Gently: Apply a gentle twisting motion or a light levering action to separate the two halves of the fob. Work slowly and systematically around the edges.
- Separate the Halves: Continue prying until the fob casing begins to split apart. Be patient, as some may be tighter than others.
- Access the Battery: Once the fob is open, the battery will be visible.
Removing the Old Jeep Cherokee Key Battery
Once your Jeep Cherokee key fob is open, removing the old battery is usually a simple matter.
Steps:
- Observe Battery Placement: Note how the old battery is situated in its holder. Pay attention to which side is facing up (+ or -).
- Use a Non-Metallic Tool: For safety and to avoid shorting any components, it’s best to use a plastic pry tool or a wooden toothpick to lift the battery out. You can also use a small, non-metallic spudger.
- Gently Lift the Battery: Carefully slide your tool under the edge of the coin cell battery and gently lift it out of its compartment. Some fobs may have a small metal clip holding the battery in place; be careful not to bend this clip.
- Dispose of Old Battery Properly: Dispose of the old battery responsibly. Many electronics stores and recycling centers offer battery recycling programs.
Installing the New Jeep Cherokee Key Fob Battery
This is where you bring your key fob back to life!
Steps:
- Prepare the New Battery: Ensure you have the correct replacement battery (e.g., CR2032). Handle the new battery by its edges; avoid touching the flat surfaces, as skin oils can sometimes affect battery performance.
- Orient the Battery Correctly: The new battery needs to be inserted with the correct polarity. Most coin cell batteries have the positive (+) side facing upwards. Check the markings on the battery compartment inside the fob for guidance.
- Insert the New Battery: Carefully place the new battery into the compartment.
- Secure the Battery: Gently press down on the battery until it sits securely in place. If there was a retaining clip, ensure it snaps back over the battery to hold it.
- Test the Fob (Optional but Recommended): Before fully closing the fob, you can often test if the battery is working. Some fobs have a small LED that should light up when you press a button. If it lights up, the battery is likely installed correctly and working.
Reassembling Your Jeep Cherokee Key Fob
Putting your Jeep Cherokee key fob back together is the reverse of opening it.
Steps:
- Align the Fob Halves: Take the two halves of the key fob and carefully align them. Make sure any buttons or internal components are properly seated before joining.
- Press Together Firmly: Once aligned, gently but firmly press the two halves together. You should hear or feel small clicks as the internal tabs engage and secure the casing. Work your way around the edges to ensure a snug fit.
- Reinsert the Emergency Key (If Applicable): If your fob has a removable emergency key, slide it back into its slot until it clicks into place.
- Test the Key Fob: Now, test all functions of your Jeep Cherokee key fob. Lock and unlock your doors, check the panic button, and any other features your fob has.
Congratulations! You’ve successfully completed your Jeep Cherokee key fob battery replacement.
When to Consider Jeep Cherokee Key Fob Repair or Replacement
While a battery change fixes most issues, sometimes the problem might be more complex. If, after replacing the battery, your Jeep Cherokee key fob still isn’t working correctly, you might be facing a different issue.
Potential Issues Beyond the Battery:
- Damaged Buttons: The rubber buttons inside the fob can wear out or become damaged, preventing proper contact with the circuit board.
- Corrosion: Moisture or liquid spills can cause corrosion on the internal circuitry, leading to malfunction.
- Circuit Board Damage: While less common, the internal circuit board itself could be damaged.
- Transmitter/Receiver Issues: In rare cases, the issue might be with the vehicle’s receiver rather than the fob itself.
When to Seek Professional Help:
- Persistent Problems: If changing the battery doesn’t solve the issue.
- Physical Damage: If the fob has been dropped, stepped on, or exposed to liquid and shows visible damage.
- Uncertainty: If you’re uncomfortable performing the battery change or reassembly.
In such scenarios, you might need to consider Jeep Cherokee key fob repair from a specialized automotive locksmith or dealership. They can diagnose the problem and either repair your existing fob or provide a Jeep Cherokee key fob replacement.
The Importance of a Jeep Cherokee Spare Key Battery
Having a Jeep Cherokee spare key battery is a smart move. You never know when your primary fob’s battery will die unexpectedly. Keeping a spare battery in your glove compartment or at home ensures you can quickly swap it out and regain full functionality of your keyless entry system without delay. This is especially useful if you have an older Jeep Cherokee or if you use your key fob frequently.
