- CONFIRM FIT - **Please confirm compatibility using the fitment guide...
- Not compatible with standard Honda key fobs that have the key sticking out...
This Honda pack impressed me with a stellar 4.7-star rating from 812 reviews and an Amazon’s Choice badge. It covers 13 different Honda models from 2008 through 2024, including the CR-V, Civic, and Accord — just make sure you have a smart fob, not the old key-sticking-out style. The 225 mAh capacity is standard for CR2032 batteries, and the DIY guide in the description makes swapping them out in a few minutes dead simple. My only gripe is the fitment guide is buried in the product images, so double-check before buying.
✅ Pros
- 4.7 stars from 812 reviews — highest rating in this comparison
- Amazon’s Choice with over 2,000 bought in the past month
- Covers 13 Honda models from 2008 to 2024
- Easy DIY replacement with no programming needed
❌ Cons
- Not compatible with Honda smart fobs that have the key sticking out
- Fitment guide is in product images, easy to miss if you’re not looking
- Does not work with Prologue or Element models

- Not compatible with standard Toyota keys in which the key is static and...
The Toyota version earned a solid 4.6 stars from 703 reviews and over 1,000 units bought in the past month — impressive numbers for a niche battery pack. It covers 13 Toyota models including the RAV4, Camry, Corolla, and Highlander, but there’s a big catch: it’s not compatible with 2021-2025 key fobs that have a silver Toyota logo on the front. The 225 mAh capacity matches the Honda pack exactly, and the DIY guide is just as easy to follow. If you drive a newer Toyota with that silver badge, you’ll need to look elsewhere.
✅ Pros
- 4.6 stars from 703 reviews with over 1,000 bought monthly
- Covers 13 Toyota models from multiple generations
- Includes the GR86, a fun exception to the silver logo rule
- Simple DIY swap with no programming required
❌ Cons
- Not compatible with 2021-2025 Toyota fobs with a silver logo
- Slightly lower rating than the Honda pack at 4.6 stars
- Does not work with standard Toyota keys that stick out of the fob
Which One Should You Buy?
I’ve spent a lot of time digging into these two battery packs, and the honest truth is that the right one for you depends entirely on what car you drive. Both deliver the same 225 mAh capacity and come in packs of two, but their fitment lists are completely different.
Deluxe CR2032 3V Key Fob Replacement Batteries for Honda is right for you if…
- You drive a 2008-2024 Honda CR-V, Civic, Accord, Pilot, or Odyssey — the pack covers 13 models total
- You want the highest-rated option at 4.7 stars from 812 customer reviews
- You want a pack that’s been bought over 2,000 times in the past month and carries an Amazon’s Choice badge
Deluxe CR2032 Key Fob Replacement Batteries for Toyota is right for you if…
- You drive a Toyota RAV4, Camry, Corolla, Highlander, Prius, Tacoma, Tundra, 4Runner, or one of six other models
- You have a Toyota smart fob without the silver logo on the front — this pack skips 2021-2025 fobs with that design
- You’re fine with a 4.6-star rating from 703 reviews and over 1,000 packs sold monthly
❌ Who Should Skip All of These?
If you drive a car that isn’t a Honda or Toyota — or if you have an older key fob with the physical key sticking out instead of a smart fob — neither of these packs will work for you. You’ll want to look for a standard CR2032 battery pack that’s not vehicle-specific.
For the most common buyer, here’s my take: if you drive a compatible Honda, grab the Honda pack — it has better ratings and more reviews. If you drive a compatible Toyota (especially one from before 2021), the Toyota pack is a great choice too, just check that silver logo first.
Frequently Asked Questions
Which battery pack has better customer ratings — the Honda or the Toyota version?
The Honda pack wins this one hands down. It holds a 4.7-star rating from 812 customer reviews, while the Toyota pack sits at 4.6 stars from 703 reviews. Both are excellent scores, but if I had to pick based on customer satisfaction alone, I’d go with the Honda pack every time.
Are these two battery packs the same size and voltage?
Yes, they are identical in that regard. Both are standard CR2032 lithium batteries delivering 3 volts with a 225 milliamp-hour capacity. The only real differences are the fitment guides — one is made for Honda smart fobs and the other for Toyota smart fobs — and the customer ratings.
Can I use the Honda battery pack in my Toyota, or the Toyota pack in my Honda?
I wouldn’t recommend it. These packs are designed specifically for each brand’s smart fob shape and terminal layout. The Honda pack covers 13 models from 2008-2024, and the Toyota pack covers 13 models as well, but they’re built for completely different key fobs. Stick with the pack that matches your car.
Will these batteries work with newer 2024 or 2025 key fobs?
It depends on which brand you drive. The Honda pack works with 2024 models like the CR-V and Civic, but the Toyota pack explicitly says it’s not compatible with 2021-2025 Toyota key fobs that have a silver logo on the front. If you have a newer Toyota, check that fitment guide carefully before buying.
Which pack is more popular based on sales?
The Honda pack is clearly the more popular choice. Over 2,000 units were bought in the past month, and it carries an Amazon’s Choice badge. The Toyota pack saw over 1,000 bought in the same period. Both are selling well, but the Honda pack has double the monthly sales volume.
How long do these CR2032 batteries last in a key fob?
While I can’t give you an exact lifespan since it depends on how often you use your fob, a standard CR2032 with 225 mAh capacity typically lasts between 1 and 3 years in a car key fob. Both packs use the same battery cell type — lithium ion — so you should get similar life out of either one.
My Final Verdict
The Deluxe Honda CR2032 pack is my clear winner. It earned a higher 4.7-star rating from more than 800 reviews, carries an Amazon’s Choice badge, and sold over 2,000 units in the past month — double the Toyota pack’s sales. The Toyota version is a solid runner-up at 4.6 stars, but only if you drive a compatible Toyota without that silver logo on the fob.
If you’re on the fence, ask yourself one question: what car do you drive? Both packs deliver the same 225 mAh capacity and come in packs of two, so your vehicle’s fitment is the only deciding factor. For Honda owners, this is an easy buy.
