Replacing the battery in your 2012 Hyundai Tucson key fob is a straightforward task that you can easily do yourself. There’s no need to visit a dealership or locksmith for this simple maintenance. This guide will walk you through the process step-by-step, saving you time and money.
Many Hyundai owners wonder if they need to reprogram their key fob after a battery change. Fortunately, for the 2012 Hyundai Tucson, reprogramming is generally not required when you only replace the battery. The key fob should continue to work seamlessly after a battery swap. Reprogramming is typically only necessary if you are replacing the entire key fob or if there’s a more significant issue with your vehicle’s system.
Before you begin, gather these few items:
- A new CR2032 battery (or the battery type specified for your 2012 Hyundai Tucson key fob – always double-check your owner’s manual or the old battery if unsure).
- A small flathead screwdriver or a similar tool to gently pry open the key fob.
Once you have your tools and replacement battery ready, follow these simple steps to change the battery in your 2012 Hyundai Tucson key fob:
-
Locate the Notch: Examine your key fob closely. You’ll typically find a small notch or seam on the side or bottom of the key fob casing. This is where you’ll need to insert your flathead screwdriver to open it.
-
Carefully Pry Open the Fob: Gently insert the tip of your flathead screwdriver into the notch. Apply a small amount of pressure and twist or pry carefully to separate the two halves of the key fob casing. Avoid using excessive force to prevent damage to the plastic.

Identify the Battery: Once the key fob is open, you’ll see the battery compartment. Take note of the battery’s orientation (+ and – sides) before removing it. This will ensure you insert the new battery correctly.
-
Remove the Old Battery: Carefully remove the old battery. You may be able to gently pry it out with your fingertip or the edge of your screwdriver.
-
Insert the New Battery: Place the new CR2032 battery into the compartment, making sure the polarity (+ and – sides) matches the markings in the battery compartment or the orientation of the old battery.

Test the Key Fob: Test the key fob by pressing the lock and unlock buttons to ensure it is working correctly. The doors of your 2012 Hyundai Tucson should respond as expected.
That’s it! You’ve successfully replaced the battery in your 2012 Hyundai Tucson key fob. This simple maintenance can save you a trip to the dealer and keep your key fob working reliably. Remember to always dispose of old batteries responsibly at designated battery recycling locations.
If you are still experiencing issues with your key fob after replacing the battery, or if you suspect a problem beyond a dead battery, it’s always best to consult with a qualified automotive locksmith or your Hyundai dealer for further diagnosis and assistance. They can help determine if there are other issues, such as a faulty key fob or a problem with your vehicle’s receiver system.
