Experiencing issues with your Lincoln MKX key fob? A common culprit is often a low or dead battery. Like all electronic devices, the key fob for your Lincoln MKX relies on a battery to function, and eventually, this battery will need replacing. If you’re finding that your key fob is becoming less responsive, or not working at all, it might be time to consider a battery replacement.
Fortunately, replacing the battery in a Lincoln MKX key fob is a straightforward process that you can easily do yourself at home. This guide will walk you through the steps and provide essential information about your key fob battery.
Understanding Your Lincoln MKX Key Fob Battery
The Lincoln MKX key fob typically uses a CR2025 battery. This is a common type of coin cell battery known for its reliability and availability. While some key fobs might also be compatible with a slightly thicker CR2032 battery, the CR2025 is generally the standard and recommended replacement.
It’s always best to double-check your owner’s manual to confirm the exact battery type for your specific Lincoln MKX model year.
A fresh CR2025 battery should have a voltage of around 3.3V. As the battery discharges with use, this voltage will gradually decrease. A voltage reading of around 3.0V indicates that the battery is getting low and may soon need replacement. Once the voltage drops below 2.9V, you can expect the key fob to become unreliable, and replacement is imminent.
Step-by-Step Guide to Replace Your Key Fob Battery
Replacing the battery in your Lincoln MKX key fob is a simple process that requires no special tools. Here’s how to do it:
-
Locate the small notch or release button on your key fob. This is usually found on the side or bottom of the fob.
-
Use a small flathead screwdriver or your car key to gently pry open the key fob casing at the notch. Be careful not to apply too much force, as you could damage the plastic casing.
-
Carefully separate the two halves of the key fob. You should now see the circuit board and the battery compartment.
-
Identify the CR2025 battery. It’s usually held in place by small clips.
-
Gently remove the old battery. You can use your fingertip or the small screwdriver to carefully pry it out. Take note of the battery’s orientation (+ side up or down) before removing it.
-
Insert the new CR2025 battery into the compartment, ensuring it’s in the correct orientation. The positive (+) side of the battery usually faces upwards.
-
Reassemble the key fob casing. Snap the two halves back together until they click securely into place.
-
Test your key fob. Press the buttons to ensure it is working correctly, locking and unlocking your doors and starting your vehicle if equipped with remote start.
Battery Life Expectancy and Tips
The lifespan of a Lincoln MKX key fob battery can vary depending on usage and environmental factors. Generally, you can expect a key fob battery to last 1-3 years. However, factors like frequent use, extreme temperatures, and electronic interference can shorten battery life.
To maximize the life of your key fob battery:
- Avoid storing your key fob in extreme temperatures. Excessive heat or cold can drain the battery faster.
- Keep your key fob away from strong electromagnetic fields. These can also drain the battery.
- Consider replacing the battery every 2 years as preventative maintenance, especially if you rely heavily on your key fob.
Troubleshooting Key Fob Issues
If you’ve replaced the battery and your key fob is still not working, there could be other issues. Here are a few troubleshooting tips:
- Check battery orientation: Ensure the new battery is installed correctly with the positive (+) side facing the right way.
- Clean battery contacts: Sometimes, dirty or corroded battery contacts can prevent proper function. Gently clean the contacts with a cotton swab and a small amount of rubbing alcohol.
- Key fob programming: In rare cases, after battery replacement, your key fob might need to be reprogrammed to your vehicle. Consult your owner’s manual for instructions on key fob programming, or visit your local Lincoln dealer.
Replacing the battery in your Lincoln MKX key fob is a simple and cost-effective way to resolve common key fob issues. By following these steps, you can ensure your key fob remains reliable and functional for years to come.
