Is your 2004 Volvo key fob not working as reliably as it used to? One of the most common issues is a dead or dying battery. Fortunately, replacing the battery in your Volvo key fob is a straightforward process you can easily do yourself, saving you time and money. This guide will walk you through each step to replace your 2004 Volvo key fob battery, ensuring you can get back to unlocking your car with ease.
What You’ll Need
Before you begin, gather these simple tools and supplies:
- Replacement Battery: You’ll need one CR2025 3V lithium coin battery. These are widely available at drugstores, supermarkets, and online retailers.
- Strong Hands (or a small lever): While you can often use your fingers, a small flat-blade screwdriver or even a 5-level mortice key can be helpful for prying open the fob.
Step-by-Step Guide to Replacing Your 2004 Volvo Key Fob Battery
Follow these simple steps to replace the battery in your 2004 Volvo key fob.
Step 1: Remove the Corner Ring
The first step is to carefully remove the small corner ring from your Volvo key fob. This ring needs to be detached to access the casing. Gently work the ring loose. Be cautious not to apply excessive force, as you could risk snapping the plastic corner of the fob.
Step 2: Open the Key Fob Casing
Once the corner ring is removed, flip open the key blade as you would to start your car. With the key flipped open, you’ll see a seam on the back of the fob. This lower section of the back panel needs to be pulled off in the direction indicated in the image.
You can use your fingers, a small flat-blade screwdriver, or even a coin to gently pry this section open. Apply steady but firm pressure.
Warning: It’s best to perform this step over a desk or table, not inside your car. As the casing opens, the battery may fall out. Having a stable surface will prevent the battery from being lost or falling into труднодоступные places in your vehicle.

Step 3: Replace the Old Battery
With the key fob open, you will see the CR2025 battery. Carefully remove the old battery. Take your new CR2025 battery and insert it into the compartment, ensuring the positive (+) side is facing upwards, as indicated by the markings in the battery compartment.
While the original battery in this example (a Panasonic) lasted for nearly 10 years, it’s recommended to replace your key fob battery every few years, or sooner if you notice decreased range or reliability. Lithium-ion batteries typically have a shelf life, but their lifespan in a key fob can vary based on usage and environmental conditions.
Tip: To keep track of when you last replaced the battery, use a permanent marker to write the replacement date or expiry date on the new battery’s top surface. This simple step can help you remember when to consider replacing it again in the future.
Step 4: Reassemble the Key Fob
Replacing the cover is as easy as taking it off. Simply align the cover with the corner ring edge of the fob first. Then, give it a firm and even push with your thumbs until it snaps securely back into place. Ensure that the casing is fully closed to protect the internal components.
Step 5: Replace the Corner Ring
The final step is to replace the small corner ring. This can be a bit fiddly. You might find it helpful to use a 5-lever mortice key or a similar thin, sturdy object to gently prise the ring open slightly. This will allow you to maneuver it back onto the fob more easily. Once positioned, ensure the ring is securely in place.
Conclusion
Congratulations! You have successfully replaced the battery in your 2004 Volvo key fob. By following these simple steps, you’ve avoided a trip to the dealership and ensured your key fob is powered up and ready to go. Regularly replacing your 2004 Volvo key fob battery will help ensure consistent remote operation and prevent unexpected lockouts.
