Understanding Your Kia Sorento Key Fob
For many Kia Sorento drivers, the key fob is simply taken for granted. Often referred to as a wireless key or remote starter, a key fob is essentially a small electronic device that uses radio frequency to communicate with your vehicle. Since their introduction decades ago and becoming standard in almost every car manufactured after 2010, key fobs have revolutionized vehicle access and control.
Your Kia Sorento key fob likely manages a range of functions, including:
- Unlocking and locking doors: Providing keyless entry to your vehicle.
- Starting the engine remotely: Allowing you to pre-heat or pre-cool your car.
- Activating comfort features: Such as heated seats or adjusting interior temperature settings in some models.
Therefore, when your Kia Sorento key fob suddenly stops working, it can be more than just an inconvenience. But before you panic, let’s explore the most common culprit.
The First Suspect: Key Fob Battery Issues
In the majority of cases, a “Kia Sorento key fob not working” issue boils down to a simple problem: a dead or weak battery. Key fobs are powered by small, watch-sized batteries discreetly housed within their casing. These batteries, while long-lasting, do eventually need replacement.
The good news is replacing a key fob battery is usually a straightforward DIY task. You can typically open the key fob casing using a small flathead screwdriver or even your car key. Once open, you can access and replace the battery.
Here’s how to check and replace your Kia Sorento key fob battery:
- Identify your battery type: Check your Kia Sorento owner’s manual to determine the correct battery type for your key fob. Common types include CR2032, CR2025, or CR1632. It’s wise to note this down or even keep a spare battery at home or in your car’s glove compartment.
- Open the key fob: Carefully pry open the key fob casing. Most fobs have a small notch or seam to insert a tool. Be gentle to avoid damaging the plastic.
- Remove the old battery: Once open, you’ll see the battery. Note its orientation (+ side up or down) before carefully removing it. You might need to use a small tool to gently pry it out.
- Insert the new battery: Install the new battery, ensuring it’s the correct type and inserted in the correct orientation.
- Close the key fob: Snap the key fob casing back together until it’s securely closed.
Key fob batteries are readily available and inexpensive, typically ranging from $5 to $25. You can purchase them at:
- Kia Dealerships: Your local Kia dealer will definitely stock the correct batteries.
- Hardware stores: Stores like Home Depot or Lowe’s usually carry a selection of watch batteries.
- Grocery stores and pharmacies: Many general retailers also sell these common batteries.
- Online retailers: Amazon and other online stores offer a wide variety of batteries.
Always ensure you purchase the correct battery type and voltage. While many batteries look similar, voltage outputs can vary, and using the wrong battery can prevent your key fob from working.
Utilizing the Smart Key Feature in Your Kia Sorento
Kia Sorento models offer a smart key feature as a backup when your key fob battery dies. The procedure varies slightly depending on your Sorento’s model year.
For Kia Sorento models prior to 2014:
These models have a designated slot inside the center console specifically for inserting your smart key in case of a dead key fob battery.
- Locate the smart key slot: Refer to your owner’s manual to find the exact location of the smart key slot in your center console.
- Insert the smart key: Insert your key fob (smart key) into the slot.
- Start the engine: With the key inserted, firmly depress the brake pedal and press the engine start/stop button. Your Kia Sorento should start.
If your vehicle doesn’t start using this method, it’s more likely that your car battery, rather than just the key fob battery, is the problem.
For Kia Sorento models manufactured after 2014:
The process is even simpler in newer models. There’s no need to find a slot.
- Press the start/stop button with the key fob: While depressing the brake pedal, press the engine start/stop button directly with your Kia Sorento key fob.
- Start the engine: Your vehicle should start right up.
Again, if your car fails to start even with this method, suspect a dead car battery as the primary issue.
When Battery Replacement and Smart Key Don’t Work
If you’ve replaced your key fob battery and tried using the smart key method, and your “Kia Sorento key fob not working” issue persists, there might be other underlying problems. These could include:
- Key fob malfunction: The key fob itself might be damaged internally due to water damage, physical impact, or general wear and tear.
- Receiver issues in the vehicle: The receiver in your Kia Sorento that detects the key fob signal might be faulty.
- Car battery problems: While you might think of the key fob battery first, a weak or dead car battery can also cause key fob issues.
- Blown fuse: A fuse related to the keyless entry system could have blown.
In these more complex scenarios, it’s best to seek professional assistance.
Seeking Professional Help for Key Fob Issues
If you’ve exhausted the basic troubleshooting steps and your Kia Sorento key fob is still not working, it’s time to consult with experts.
- Contact your Kia Dealer: Your local Kia dealership has certified technicians who are experts in diagnosing and repairing Kia Sorento key fob and related system issues. They can perform more in-depth diagnostics, reprogram key fobs, and address any electrical problems in your vehicle.
- Qualified Mechanic: A trusted and qualified mechanic specializing in automotive electronics can also diagnose and fix key fob problems.
Before you go to a dealer or mechanic:
- Check your car battery: Ensure your car battery is healthy and properly charged.
- Review your owner’s manual: Re-read the key fob and smart key sections of your owner’s manual for any specific instructions or troubleshooting tips for your model year.

While technology offers great convenience, it’s wise to be prepared for potential failures.
