    If your key fob isn’t working, you may need to change the battery. In this blog post, we’ll show you how to do it. We’ll also share some tips on how to keep your key fob working well. Stay safe and happy driving!


    What Type Of Battery Is Needed For The Key Fob?

    The battery type needed for the key fob depends on the make and model of the vehicle. Most key fobs use either a CR2032 or a CR2025 battery. These are 3-volt lithium coin batteries that are relatively easy to find at most stores that sell batteries. To change the battery, start by locating the small screw on the back of the key fob.

    Use a small Phillips head screwdriver to remove the screw. Once the screw is removed, the back of the key fob will come off, revealing the battery. Gently pry out the old car key battery and insert the new one, being careful to match the positive and negative sides. Once the new battery is in place, reassemble the key fob and test it out to make sure it’s working properly.

But before you can do that, you’ll need to remove the old battery. Here’s a step-by-step guide to removing the battery from a key fob:

    1. Start by locating the battery cover. This is usually located on the back of the key fob.
    2. Use a small screwdriver or knife to pry open the battery cover. Be careful not to damage the cover as you do this.

    4. Insert the new battery into the housing, making sure that the positive and negative terminals are aligned correctly.
    5. Close the battery cover and screw it back into place, if necessary.
    6. Test your key fob to make sure that it’s working properly. If not, repeat these steps until it does.

    Why It’s Important To Keep Your Key Fob In Good Condition?


    Your key fob is an important part of your car’s security system. If it stops working properly, it could leave your car vulnerable to theft or break-ins. It’s important to keep your key fob in good condition so that it can continue to protect your car.


    Here are a few tips for doing so:

    1. Keep it clean: Wipe down your key fob with a soft cloth regularly to remove any dirt or grime that could potentially interfere with its signal.

    2. Avoid extreme temperatures: Don’t leave your key fob in direct sunlight or in a hot car, as the heat can damage the electronic components inside. Similarly, cold temperatures can also cause problems, so don’t keep it in your freezer or leave it outside in the cold for extended periods of time.

    3. Keep it away from water: Water can damage the electronic components inside your key fob, so avoid getting it wet if possible. If it does get wet, dry it off as soon as possible with a soft cloth.

    4. Don’t store it next to other electronics: Mobile phones, laptops, and other electronic devices can interfere with your key fob’s signal. So, it’s best to keep them stored separately.

    5. Keep an eye on the battery: Most key fobs use CR2032 batteries, which are readily available at most stores. If your key fob starts to behave erratically or the button presses stop working, it’s likely time to replace the battery.

    By following these tips, you can help ensure that your key fob stays in good condition and continues to protect your car effectively.

    Fob batteries generally last between one and three years. If your fob starts to feel sluggish or you notice the battery icon on the display is no longer solid, it’s time to replace the battery.
