Recognizing the Signs: When to Replace Your Key Fob Battery
Before your key fob completely gives up, it will usually give you some warning signs. Keep an eye out for these indicators that your 2019 Land Rover Discovery Sport key fob battery is nearing the end of its life:
- Reduced Operating Range: You need to be much closer to your vehicle than usual for the key fob to lock, unlock, or activate the panic alarm.
- Intermittent Functionality: Sometimes the buttons work, and sometimes they don’t, requiring multiple presses or attempts.
- Dashboard Warning Message: Some Discovery Sport models may display a warning message on the dashboard indicating a low key fob battery.
- Key Not Detected: In some cases, the vehicle may occasionally fail to detect the key fob inside the car, especially when trying to start the engine.
If you’re experiencing any of these issues, it’s a strong indication that a key fob battery replacement is in order.
What You’ll Need for the Replacement
Fortunately, replacing the battery in your 2019 Land Rover Discovery Sport key fob requires minimal tools and readily available parts. Here’s what you’ll need:
- New Battery: You’ll need one CR2032 3V lithium coin cell battery. This is a very common type of battery and can be purchased at most drugstores, supermarkets, and online retailers.
- Small Flathead Screwdriver or Key: A small flathead screwdriver or even the emergency key blade from your key fob itself will be needed to open the key fob casing.
- Soft Cloth (Optional): A soft cloth can be used to protect the key fob casing from scratches during the opening process.
Step-by-Step Guide to Replacing Your Key Fob Battery
Now, let’s get down to the actual battery replacement. Follow these simple steps:
-
Locate the Release Latch or Notch: Examine your Land Rover Discovery Sport key fob. You’ll find a small release latch or notch, typically on the side or bottom of the key fob casing.
-
Release the Emergency Key Blade (If Applicable): If your key fob has a separate emergency key blade, remove it first. This often helps to reveal the notch or provides better access to it.
-
Use the Screwdriver or Key to Open the Casing: Carefully insert the tip of your small flathead screwdriver or the emergency key blade into the notch. Gently twist or pry to separate the two halves of the key fob casing. Be patient and avoid using excessive force to prevent damage to the plastic casing.
-
Identify and Remove the Old Battery: Once the casing is open, you’ll see the CR2032 battery. Note the orientation of the battery (usually the positive side facing up). Gently pry out the old battery. You can use your fingernail or the tip of the screwdriver to carefully lift it out.
-
Insert the New CR2032 Battery: Take your new CR2032 battery and insert it into the battery compartment. Ensure the positive (+) side of the battery is facing upwards, matching the orientation of the old battery. Push the battery firmly into place until it is securely seated.
-
Reassemble the Key Fob Casing: Carefully align the two halves of the key fob casing and snap them back together. Press firmly until you hear a click, ensuring the casing is completely closed and secure.
-
Test Your Key Fob: Press the buttons on your key fob to test if it is working correctly. Try locking and unlocking your 2019 Land Rover Discovery Sport from a reasonable distance to confirm the new battery has resolved the issue.
Tips for a Smooth Battery Replacement
- Work on a Clean Surface: Choose a clean, well-lit workspace to avoid losing any small parts.
- Be Gentle: Avoid using excessive force when opening the key fob casing to prevent damage.
- Double-Check Battery Orientation: Ensure the new battery is inserted with the correct polarity (+ side up) for proper function.
- Dispose of Old Battery Properly: Lithium batteries should be disposed of responsibly. Check your local regulations for battery recycling.
