If you drive a Nissan, you’ve likely experienced the telltale signs of a dying key fob battery: reduced range, the need to press buttons multiple times, or a complete failure to unlock the doors. Replacing the battery is a straightforward maintenance task, and this pack of two CR2032 batteries is one option for doing it yourself. Here’s a closer look at what you get and how it performs in real-world use.
The product consists of two CR2032 coin-cell batteries, which are commonly used in Nissan key fobs from various model years. The batteries are 3V lithium, the standard chemistry for this application. They arrive in retail packaging, and each battery is individually sealed to preserve shelf life. The pack of two is convenient because it provides a spare, either for a second fob or for future replacement. There’s no included tool, but most key fobs can be opened with a small flathead screwdriver or the emergency key that’s often built into the fob itself.
In practice, replacing the battery is a five-minute job. You pry open the fob casing, remove the old battery, and insert the new one with the positive side facing up (check your owner’s manual for orientation). The batteries fit snugly and make proper contact. After replacement, the fob typically regains full functionality, with range returning to normal. These batteries are not rechargeable, so when they die, you simply replace them again. Under typical use, a CR2032 in a key fob lasts anywhere from one to three years, depending on how often the buttons are pressed and environmental factors like temperature. This pack should cover you for several years.
One limitation is that these are standard CR2032 batteries, not necessarily premium brands. While they meet the voltage and size specifications, their longevity may not match that of name-brand batteries like Duracell or Energizer. In our testing, they performed adequately, but if you’re looking for maximum lifespan, you might consider a higher-end brand. Also, the packaging is minimal; there’s no plastic case to store the spare, so you’ll need to find a safe spot for it. Additionally, some Nissan models may use a different battery size (like CR2025), so it’s crucial to verify your fob’s requirements before purchasing.
Compared to buying batteries individually at a store, this pack offers convenience and cost savings. However, if you prefer the assurance of a well-known brand, you might opt for a two-pack of Duracell CR2032s, which often cost a bit more but may last longer. On the other hand, if you’re comfortable with generic batteries, this pack is a budget-friendly alternative. Another option is to have the battery replaced at a dealership or auto parts store, but that typically costs more and takes time.
This product is suitable for Nissan owners who are comfortable with a simple DIY task and want a spare battery on hand. It’s also a good choice for those who prefer to avoid the hassle of visiting a store. However, it’s not for you if you’re unsure about the battery size for your specific fob, or if you prefer to have a professional handle the replacement. Additionally, if you own a Nissan with a key fob that requires a different battery type, this pack won’t work.
In terms of performance, these batteries deliver the expected 3V output and fit correctly. They don’t offer any special features like extended life or leak resistance, but they get the job done. The lack of a brand name might be a concern for some, but for a low-drain device like a key fob, the difference is often negligible. Just be aware that if you have a newer Nissan with a proximity key system, the battery may drain faster, so you might need to replace it more often.
Overall, this two-pack of CR2032 batteries is a practical, no-frills solution for Nissan key fob battery replacement. It’s affordable, convenient, and works as expected. While it may not have the longevity of premium brands, it’s a reasonable choice for budget-conscious drivers who don’t mind a little DIY. Just double-check your fob’s battery size and be prepared to replace it again in a year or two.
