Is your 2015 Lincoln MKZ key fob not working as reliably as it used to? A common culprit is a low or dead battery. Fortunately, replacing the battery in your Lincoln MKZ key fob is a straightforward process you can easily do yourself. This guide will walk you through each step, ensuring you can get your key fob back in top shape and avoid any unnecessary trips to the dealership.
Before we dive into the battery replacement, it’s helpful to understand the evolution of Lincoln key fobs. As mentioned in discussions among Lincoln owners, models like the 2014 MKZ used a key fob design shared with Ford vehicles. However, Lincoln recognized the key fob as a crucial touchpoint for their luxury brand. Between 2014 and 2017, Lincoln upgraded to a more substantial and premium-feeling key fob, distinct from Ford’s. This enhanced fob, while perhaps a bit bulkier, provides a more luxurious feel, aligning with the Lincoln brand experience.
Whether you have the earlier or later version of the fob, the battery replacement process is similar. Here’s how to replace the battery in your 2015 Lincoln MKZ key fob:
Step-by-Step Battery Replacement
-
Identify Your Key Fob Type: While the internal battery access is similar, knowing your fob type can be helpful. The 2015 Lincoln MKZ uses a remote that may look similar to later models but will definitely be the more “substantial” feeling fob compared to older Ford-shared designs.
-
Gather Your Tools: You’ll need a small flathead screwdriver or a similar tool to gently pry open the key fob. You’ll also need a replacement battery. The 2015 Lincoln MKZ key fob typically uses a CR2032 battery. You can find these at most drug stores, grocery stores, and online retailers.
-
Locate the Notch to Open the Fob: Examine the edges of your key fob. You should find a small notch or slot, usually on the side or bottom of the fob. This is where you’ll insert your flathead screwdriver.
-
Carefully Pry the Fob Open: Insert the tip of your flathead screwdriver into the notch. Gently twist or pry to separate the two halves of the key fob. Take your time and avoid using excessive force to prevent damaging the plastic casing.
-
Access the Battery Compartment: Once the fob is open, you’ll see the circuit board and the battery compartment. The battery is usually held in place by small clips.
-
Remove the Old Battery: Note the orientation of the old battery (positive side up or down) before removing it. You can use your fingertip or the tip of the screwdriver to gently pry the old battery out of its compartment.
-
Install the New Battery: Place the new CR2032 battery into the compartment, ensuring the orientation is correct (match the orientation of the old battery). Push down gently until the battery is securely in place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob and press them back together until they snap closed. Ensure there are no gaps and the fob feels securely closed.
-
Test Your Key Fob: Try using all the buttons on your key fob to lock, unlock, and remote start your 2015 Lincoln MKZ. If everything works as expected, you’ve successfully replaced the battery!
Starting Your 2015 Lincoln MKZ with a Dead Key Fob Battery
Even with a dead key fob battery, you can still start your 2015 Lincoln MKZ. Lincoln vehicles are equipped with a backup system. Here’s how to start your car when the fob battery is dead:
-
Locate the Center Console Cupholder: In your 2015 Lincoln MKZ, find the center console cupholder area.
-
Remove the Rubber Mat/Liner: Inside the cupholder, you’ll likely find a removable rubber mat or liner at the bottom. Lift and remove this liner.
-
Find the Key Fob Slot: Underneath the liner, you will discover a designated slot or cutout specifically designed for the key fob.
-
Place the Key Fob in the Slot: Insert your Lincoln MKZ key fob into this slot. Ensure it’s placed securely in the designated position.
-
Start Your Vehicle: With the key fob in the slot, you should now be able to start your Lincoln MKZ as you normally would, by pressing the brake pedal and then the start button.
This feature is incredibly helpful in situations where your key fob battery dies unexpectedly, allowing you to start your car and get to a place where you can replace the battery.
Conclusion
Replacing the battery in your 2015 Lincoln MKZ key fob is a simple maintenance task that any owner can perform. By following these steps, you can save time and money while ensuring your key fob remains functional. Remember to use the correct CR2032 battery and to handle the key fob components with care.
