What is the battery model for Volvo car keys?
4 Answers
Volvo key battery model is CR2032. CR2032 is a lithium manganese dioxide battery, named according to IEC standards. Among them: C - indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R - indicates that the battery is cylindrical in shape, with F used instead if it is square; 20 - indicates the battery diameter is 20mm; 32 - represents the battery height is 3.2mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity varies between 200-240mAh, depending on the manufacturer's quality. The shelf life of CR2032 is typically 5 years. If the manufacturing level is low or quality control is poor, its lifespan can be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. Under ideal usage conditions (sealed, room temperature, no moisture interference, etc.), the lifespan can be further extended to 8 years or even 10 years. Generally, replacing a car key battery only requires the following 3 steps: Step 1: Remove the mechanical key. Press the buckle on the side of the smart key to remove the mechanical key. Step 2: Open the battery cover. After removing the mechanical key, you can see a deep slot and a shallow slot at the top of the smart key. The deep slot is the keyhole, while the shallow slot is used to open the battery cover. Insert the mechanical key into the shallow slot and pry it outward to open the battery cover. Once opened, you can see the coin cell battery. Gently pry it out to remove the battery. Step 3: Replace the new battery. Install the new battery, then reattach the battery cover and mechanical key in sequence to complete the battery replacement.
Our family has been driving a Volvo for over a decade, and the key fob batteries have mostly been CR2032 models, those small coin-shaped batteries. I've replaced them myself several times, and it's quite convenient. After opening the back cover of the key, you can see the battery. Just use a small tool to gently pry it open, take out the old battery (be careful not to flip it upside down), and insert the new one with the positive side facing up. These batteries can be bought for just a few dollars at supermarkets or online stores, so there's no need to go to a 4S dealership, which saves both hassle and money. Typically, you'll need to replace the battery every one or two years, especially in cold weather when the battery tends to drain faster and the buttons become less responsive. Changing it early can prevent the frustration of pressing the button repeatedly with no response when trying to unlock the car. It's a good idea to keep a spare battery in your bag for emergencies.
The Volvo car key battery is a CR2032, that small round flat battery. I replaced it myself for my XC60, and it was a simple operation that took just a few minutes. To remove the key back cover, use a coin to pry open the latch, take out the old battery, install the new one, and test the buttons. Battery life depends on usage frequency, averaging about a year and a half. If the remote control distance shortens, it's a sign that the battery is running low. For new batteries, I recommend buying from JD.com or a hardware store, choosing reputable brands to avoid leakage from cheap ones damaging the internal circuits. The cost is just around ten yuan, so don't get ripped off. This battery model is highly versatile and fits many cars. A DIY tip is to ensure the back cover is tightly closed after replacement to prevent dust and water ingress.
The CR2032 battery is the standard model for Volvo keys due to its suitable size and stable voltage. I use it in my V90, and replacing it solves any malfunction every time. The lifespan is about 1-2 years, depending on how frequently you press the buttons. If the remote response slows down or the indicator light weakens, it's time for a replacement. This type of lithium battery is widely available and easy to purchase. When replacing, be careful not to reverse the positive and negative terminals. The design is simple, making it convenient for users to operate themselves—just open the back cover with a small screwdriver to save time. It has good compatibility, and other brands like Toyota keys may also use similar models to ensure strong universality.
