Is your 2020 Lincoln Corsair key fob not working as reliably as it used to? You might be facing a common issue: a low or dead battery. Fortunately, replacing the battery in your Lincoln Corsair key fob is a straightforward process that you can easily handle yourself, saving you time and a trip to the dealership. This guide will walk you through each step, ensuring you can quickly get your key fob back in top working condition.
Understanding Your Lincoln Corsair Key Fob Battery
The 2020 Lincoln Corsair key fob typically uses a CR2450 type battery. These are 3-volt lithium coin cell batteries, widely available at most drugstores, hardware stores, and online retailers. It’s always a good idea to confirm the exact battery type specified in your owner’s manual to be absolutely sure. Having the correct battery type is crucial for optimal key fob performance and longevity.
Knowing the battery type beforehand will save you a trip back to the store. Before you start, gather the necessary tools and the replacement battery to make the process smooth and efficient.
Step-by-Step Battery Replacement Process
Replacing the battery in your 2020 Lincoln Corsair key fob is a simple task that should take only a few minutes. Follow these detailed steps:
Step 1: Gather Your Tools and Battery
Before you begin, make sure you have the following:
- New CR2450 Battery: Purchase a fresh CR2450 3-volt lithium battery.
- Small Flathead Screwdriver or Key Fob Tool: You’ll need a small tool to gently pry open the key fob. A small flathead screwdriver from an eyeglass repair kit works perfectly. Many key fob battery replacement kits also come with a plastic prying tool which is ideal to prevent scratches.
- Soft Cloth (Optional): Using a soft cloth can protect the key fob from scratches during the process.
Step 2: Locate the Emergency Key and Remove It
On your Lincoln Corsair key fob, you’ll find a small release latch. Locate this latch and slide or press it to release the emergency key blade. Pull the key blade out and set it aside. This step is necessary to access the battery compartment.
Step 3: Pry Open the Key Fob Casing
With the emergency key removed, you’ll see a small slot or seam where the two halves of the key fob casing join together. This is where you’ll insert your flathead screwdriver or prying tool.
- Carefully insert the tip of your tool into the slot.
- Gently twist or pry to separate the two halves of the key fob. Work your way around the seam, gently prying until the casing starts to open. Avoid using excessive force to prevent damage to the casing.

Step 4: Remove the Old Battery
Once the key fob casing is open, you’ll see the battery inside. The battery is usually held in place by small clips.
- Carefully note the orientation of the battery (positive side up or down) before removing it. This is crucial for installing the new battery correctly.
- Use your fingertip or the tip of your tool to gently nudge the old battery out of its compartment. Be careful not to damage the battery contacts.
Step 5: Install the New Battery
Now it’s time to install the new CR2450 battery.
- Insert the new battery into the compartment, making sure the orientation matches the old battery. The positive (+) side of the battery usually faces upwards, but double-check the markings inside the compartment.
- Press down gently to ensure the battery is securely seated in its place.

Step 6: Reassemble the Key Fob
With the new battery in place, it’s time to put the key fob back together.
- Carefully align the two halves of the key fob casing.
- Press them firmly together until they snap securely back into place. You should hear a click or feel the casing close tightly.
- Slide the emergency key blade back into the key fob until it clicks into its locked position.
Step 7: Test Your Key Fob
Finally, test your key fob to ensure it’s working correctly. Try locking and unlocking your 2020 Lincoln Corsair remotely, and test the panic button to confirm all functions are restored. If everything works as expected, you’ve successfully replaced your Lincoln Corsair key fob battery!
Troubleshooting Common Issues
If your key fob still doesn’t work after replacing the battery, consider these troubleshooting tips:
- Battery Orientation: Double-check that you installed the new battery with the correct polarity (+ side up or down). Incorrect orientation is a common mistake.
- Battery Type: Ensure you used the correct CR2450 battery. Using a different type might not provide the necessary voltage.
- Battery Contact: Make sure the battery contacts inside the key fob are clean and making good contact with the battery. You can gently clean them with a cotton swab if needed.
- Key Fob Damage: If your key fob has been dropped or damaged, internal components might be broken. In this case, you may need to consider professional key fob repair or replacement.
- Vehicle Issues: In rare cases, the issue might not be the key fob battery but a problem with your vehicle’s receiver. If you suspect this, consult your Lincoln owner’s manual or contact a qualified automotive technician.
Extending Your Key Fob Battery Life
To maximize the lifespan of your 2020 Lincoln Corsair key fob battery, consider these tips:
- Avoid Extreme Temperatures: Extreme heat or cold can drain battery life faster. Try to keep your key fob away from direct sunlight or freezing temperatures.
- Limit Excessive Button Pressing: Avoid pressing buttons unnecessarily when out of range of your vehicle.
- Store Key Fob Away from Electronic Devices: Strong electromagnetic fields from devices like smartphones or microwaves could potentially interfere with key fob signals and drain battery.
- Regular Battery Checks: Be mindful of your key fob’s range and responsiveness. If you notice a decrease in performance, replacing the battery proactively can prevent unexpected issues.
Conclusion
Replacing the battery in your 2020 Lincoln Corsair key fob is a simple and cost-effective maintenance task.
