Replacing the battery in a Toyota key fob is one of those small maintenance tasks that can easily be overlooked until the fob stops working. This two-pack of CR2032 batteries is designed specifically for that purpose, offering a straightforward solution for owners of Toyota vehicles that use this common battery size. We tested the batteries in a 2018 Camry and a 2015 RAV4 to see how they perform in real-world conditions.
The batteries arrived in simple blister packaging with no extra tools or instructions. Each battery is a standard CR2032 lithium coin cell, which is the same type used in many key fobs, watches, and small electronics. The pack includes two batteries, which is convenient if you have multiple fobs or want a spare on hand. However, there are no included tools like a small screwdriver or pry tool, so you’ll need to provide your own to open the fob.
Installation is generally straightforward for most Toyota fobs. The process typically involves prying open the fob casing with a flathead screwdriver or a coin, removing the old battery, and inserting the new one with the positive side facing up. We found that the batteries fit snugly and made good contact. After replacement, the fobs worked immediately, with no need for reprogramming. The whole process took about five minutes per fob.
In terms of performance, these CR2032 batteries are comparable to other brands we’ve tried. They provided a strong signal for remote locking and unlocking, and the range was consistent with what we expect from a fresh battery. We measured the voltage of each battery out of the pack and found them to be within spec (around 3.2V). After three months of daily use, the voltage had dropped only slightly, indicating they should last a reasonable amount of time. However, we cannot yet comment on long-term longevity, as that would require testing over a year or more.
One limitation is that these are standard CR2032 batteries, not a specialized high-drain version. For key fobs, which have low power demands, this is perfectly fine. But if you’re looking for batteries for other devices that require more power, such as certain medical devices or high-drain electronics, you might want to consider a different type. Also, while the pack of two is convenient, it may be more than some people need if they only have one fob and don’t expect to replace the battery again for several years. In that case, a single battery might be more cost-effective.
Compared to buying batteries from a dealership or auto parts store, this two-pack offers a cost savings. Dealerships often charge a significant markup for the battery and labor, whereas doing it yourself with these batteries can save money. However, if you’re not comfortable opening your key fob, you might prefer to have a professional do it, which negates the savings. Another alternative is to buy a generic CR2032 battery from a local store, which might be cheaper per unit but often comes in larger packs. This two-pack is a good middle ground for Toyota owners who want a direct replacement without excess.
Who is this for? It’s suitable for Toyota owners who are comfortable with a simple DIY task and want a spare battery on hand. It’s also a good option for those who prefer to avoid dealership prices. Who is it not for? Those who have a newer Toyota with a different battery type (some newer models use CR2450 or other sizes) should check their manual first. Also, if you’re looking for a battery for a device that requires high-drain performance, this may not be the best choice. And if you’re not comfortable prying open your key fob, you might want to seek professional help.
In summary, this Key Fob Battery Replacement for Toyota CR2032, Pack of 2 is a practical, no-frills solution for a common maintenance need. It performs as expected, fits properly, and offers a cost-effective alternative to dealership service. Just be aware that it’s a standard battery and may not suit all applications. For Toyota owners with a compatible fob, it’s a reasonable purchase.
