The 2018 GMC Yukon is a powerful and luxurious SUV, but even the most advanced vehicles can be hampered by a simple issue: a dead key fob battery. If your key fob is no longer unlocking your Yukon, it’s time to replace the battery. This guide will walk you through the process of changing the key fob battery for your 2018 GMC Yukon, ensuring you’re back on the road in no time.

Understanding Your Key Fob

Before you begin, it’s essential to understand the components of your Yukon’s key fob. The key fob consists of a few main parts:

• The Case: This is the outer shell that protects the internal components.
• The Battery: This provides the power for the key fob’s functions.
• The Circuit Board: This is the electronic component that receives signals and transmits them to your Yukon.
• Buttons: These are the physical buttons you press to lock, unlock, or start your vehicle.

Gather Your Supplies

Before you begin the battery replacement process, ensure you have the following items:

• A new CR2032 battery: This is the standard battery size for most key fobs. You can find these at most auto parts stores, convenience stores, or online.
• A small flathead screwdriver: This will be used to pry open the key fob.
• A pair of tweezers (optional): This can be helpful for removing the old battery.

Locating the Battery Compartment

The battery compartment is typically located on the back of the key fob. It may be hidden behind a small cover or simply a seam in the case. To find it, look for:

• A small seam or gap: This could indicate the location of the battery compartment.
• A small button or release tab: Pressing this may open the battery compartment.
• A small arrow or symbol: This might point to the location of the battery compartment.

Opening the Battery Compartment

Once you’ve located the battery compartment, you can open it using a small flathead screwdriver. Gently insert the screwdriver into the seam or gap and pry open the compartment. Be careful not to apply excessive force, as this could damage the key fob.

Removing the Old Battery

Once the battery compartment is open, you’ll see the old battery. Use your fingers or tweezers to gently remove the battery. Be sure to note the positive (+) and negative (-) sides of the battery, as you’ll need to insert the new battery with the same polarity.

Installing the New Battery

With the old battery removed, insert the new CR2032 battery into the compartment. Ensure the positive (+) side of the battery faces the positive (+) terminal in the compartment, and the negative (-) side faces the negative (-) terminal.

Closing the Battery Compartment

Once the new battery is installed, gently push the battery compartment closed. You should hear a click as it snaps shut. Make sure the compartment is completely closed to ensure proper contact with the battery.

Testing Your Key Fob

After replacing the battery, test your key fob by pressing the lock, unlock, and panic buttons. If the key fob is working correctly, you should hear the car’s locks engage or disengage, and the panic alarm should sound.

Troubleshooting

If your key fob still isn’t working after replacing the battery, try the following troubleshooting steps:

• Check the battery contacts: Ensure the battery is making proper contact with the terminals in the compartment.
• Clean the battery contacts: If the contacts are dirty or corroded, clean them with a cotton swab dipped in rubbing alcohol.
• Check the key fob’s range: The key fob may have a limited range, especially if it’s old or the battery is low. Try moving closer to your Yukon and testing the key fob again.
• Reset your key fob: Depending on your Yukon model, you may be able to reset your key fob by following the instructions in your owner’s manual.

Keeping Your Key Fob in Top Shape

To ensure your key fob continues to work properly, follow these tips:

• Store your key fob in a cool, dry place: Avoid exposing your key fob to extreme temperatures or moisture.
• Keep your key fob away from magnets: Magnets can interfere with the key fob’s electronic components.
• Replace the battery regularly: Even if your key fob is still working, it’s a good idea to replace the battery every 12-18 months.
• Clean your key fob regularly: Dust and dirt can accumulate on the key fob and interfere with its functionality.
