This guide from the experts at keyfobprog.com will walk you through each step of a Volvo key fob battery replacement, ensuring your key fob is powered up and working perfectly again. We’ll cover everything you need to know about changing your Volvo key battery, from the tools you’ll need to recognizing the signs of a low battery.
What You’ll Need to Change Your Volvo Key Fob Battery
Before you begin, gather these simple tools and materials for a smooth Volvo key fob battery replacement:
- A Clean, Static-Free Work Surface: A wood cutting board or any non-metallic surface will work perfectly. Avoid carpets or fabrics that can generate static electricity.
- Small Flathead Screwdriver or Coin: This will be used to gently open the key fob case and the battery compartment.
- New 3V CR2032 Battery: This is the standard Volvo key fob battery type for most models from 2016 onwards. Always double-check your Volvo owner’s manual to confirm the exact battery specification for your specific vehicle model and year. Using the correct battery is crucial for optimal performance.
- Rubber Gloves (Optional but Recommended): Wearing rubber gloves helps to prevent skin oils and static discharge from damaging the sensitive electronic components and contact surfaces inside your key fob.
Once you have everything prepared, find a comfortable and well-lit space where you can focus on the task without distractions.
Step-by-Step Guide: Replacing Your Volvo Key Fob Battery
Follow these detailed steps to replace your Volvo key fob battery quickly and efficiently:
-
Position the Key Fob: Place your Volvo key fob on your clean work surface with the Volvo logo facing upwards. Note that for some models, the orientation of the logo may be reversed in these initial steps, but the process remains fundamentally the same.
-
Release the First Cover: Locate the small button or release catch near the key-ring loop section of your key fob. Slide this button firmly towards the key-ring hole and hold it in that position. You should feel the cover begin to loosen. If it doesn’t release immediately, try sliding the button again while applying gentle pressure to the cover seam.
-
Gently Remove the First Cover: While still holding the button, use your fingernail or the edge of a plastic opening tool (if you have one) to gently pry the first cover away from the key fob body. Work along the seam, being careful not to force it and avoid using excessive force with a metal screwdriver at this stage to prevent scratches.

Locate and Slide the Second Button: Underneath the cover you just removed, you’ll find another small button, often near the manual key. Slide this second button sideways and keep it held in that position.
-
Flip and Remove the Second Cover: While continuing to hold the second button, flip the key fob over to the other side. Just as you did with the first cover, gently pry the second cover off using your fingernail or a plastic tool, working along the seam. Releasing the second button after the cover is loose is fine.

Identify the Battery Hatch: With both covers removed, you will now see a circular section with a rectangular slot. You should see the words “close” and “open” inscribed near this circular area, along with an arrow pointing towards “close”. This is the battery hatch that protects the battery compartment.
-
Open the Battery Hatch: Take your flathead screwdriver or a coin. Insert the flathead of the screwdriver or the edge of the coin into the rectangular slot on the battery hatch. Turn the hatch in the direction indicated by the word “open,” ensuring the arrow now points to “open.” You may need to apply a little pressure, but the hatch should turn relatively easily.

Pry Open the Battery Hatch: Once the battery hatch is in the “open” position, use your fingernail or the flathead screwdriver to carefully pry the hatch away from the key fob body. It should pop open with minimal effort. Be gentle to avoid damaging the plastic clips.
-
Wear Rubber Gloves (If Using): Now is the time to put on your rubber gloves if you are using them. This will protect the battery and electronic contacts from skin oils and potential static damage.
-
Remove the Old Battery: Carefully pry the old CR2032 battery out of its socket. The easiest way to do this is to gently lift the side of the battery closest to the key-ring loop first. You can use your fingernail or the flathead screwdriver to help, but be extremely careful not to scratch or damage any of the clips or touch the gold-colored electronic contact surfaces within the battery compartment.

Insert the New Battery: Take your new CR2032 battery. It’s crucial to insert it with the correct polarity. The positive side of the battery (marked with a “+”) must face upwards. Angle the new battery slightly downwards as you insert it into the socket, sliding the edge of the battery underneath the two clips that are furthest from the key-ring loop first.
-
Secure the New Battery: Continue sliding the Volvo key fob battery forward into the compartment until the clips engage and hold it in place. You should feel a slight click or resistance as the clips lock the battery in. Gently press down on the battery to ensure all clips are securely holding it.

Reassemble the Key Fob: Now that the Volvo key fob battery replacement is complete, it’s time to reassemble your key fob. Reverse the disassembly process.
-
Resecure the Battery Hatch: Place the battery hatch back into its recess and turn it with your screwdriver or coin until the arrow points back to “close,” ensuring it is firmly secured.

Symptoms of a Low Volvo Key Fob Battery
Knowing the signs of a weakening Volvo key fob battery can help you replace it proactively and avoid being caught out. Here are the common symptoms indicating it’s time for a Volvo car key battery change:
- Unresponsive Key Fob Buttons: This is the most obvious sign. You press the lock, unlock, or trunk button, and your Volvo doesn’t respond.
- Decreased Key Fob Range: You need to be much closer to your Volvo than usual for the key fob to work. The effective range of the remote starts to diminish noticeably.
- Intermittent Button Response: You have to press the buttons multiple times, or press them harder than usual, to get your Volvo to respond.
- Delay in Vehicle Response: There’s a noticeable delay between pressing a button on your key fob and your Volvo performing the action (locking, unlocking, etc.).
- “Key Fob Battery Low” Dashboard Warning: Many newer Volvo models feature a warning light on the dashboard that specifically alerts you when the key fob battery is low. Pay attention to this warning when it appears.
What to Do If Your Volvo Key Fob Battery Dies Completely
Even with a dead Volvo key battery, you are not locked out of your car. Volvo provides a couple of convenient ways to access and start your vehicle:
- Volvo Cars App: If you have a Volvo subscription and the Volvo Cars app set up, you can use your smartphone to remotely unlock and even start your Volvo. This is a handy digital backup for a dead key fob battery.
- Manual Key Access: As mentioned in the battery replacement steps, your Volvo key fob contains a physical, manual key. You can access this key by removing the key fob covers. The manual key lock cylinder is typically located underneath the door handle on the driver’s side. Simply insert the manual key into the lock cylinder to unlock your Volvo the traditional way.
- Direct Contact Starting (Possible Emergency Measure): In some very rare cases where the battery has a minimal residual charge, you might be able to start your Volvo by holding the key fob directly against the door handle or steering column (check your owner’s manual for the exact location) and pressing the engine start/stop button. This is not a reliable long-term solution, but it might work in an emergency.
Choosing the Right Replacement Battery
Using the correct, high-quality replacement battery is important for the longevity and reliable performance of your Volvo key fob. Always use a 3V CR2032 lithium coin cell battery unless your owner’s manual specifies a different type.
When purchasing a replacement, opt for reputable brands to ensure quality and a longer lifespan. Avoid generic or low-quality batteries, as they may not last as long or perform as reliably.
When to Seek Professional Help
While Volvo key fob battery replacement is generally a simple DIY task, there are situations where you might need professional assistance:
- Key Fob Reprogramming: In rare cases, after a battery replacement, your Volvo key fob might need to be reprogrammed to your vehicle, especially if the battery was dead for an extended period. If your key fob is unresponsive after a battery change, contact a certified Volvo service center.
- Difficulty with Battery Replacement: If you encounter any difficulties opening your key fob, removing the battery, or are uncomfortable performing the replacement yourself, don’t hesitate to seek help from Volvo technicians.
- Key Tag Battery Replacement (Not Possible DIY): Remember that the special buttonless Volvo key tag, designed for water and dust resistance, does not allow for DIY battery replacement. If your key tag battery dies, you will need to order a replacement key tag and have it paired to your vehicle by a Volvo dealer.
