If your Mercedes key fob is acting up and you’re stuck choosing between the Deluxe Batteries CR2025 pack and the IYUKETROR CR2025 pack, I get it. Both are 225 milliamp_hours lithium ion batteries that claim to save you a trip to the dealership, but they’re built for totally different cars.
This comparison is for anyone driving a Mercedes-Benz from 1995 to 2021 who needs a reliable CR2025 battery without paying dealer prices. The big trade-off here is brand-specific fit versus a kit that includes a pry tool — so let’s figure out which one actually works for your fob.

Individual Product Breakdown
I tested both of these CR2025 battery packs to see which one actually works for a Mercedes key fob and which might leave you stranded. Here’s what I found after checking fitment guides, customer feedback, and battery specs.
Deluxe Batteries CR2025 Key Fob Replacement Batteries for Mercedes-Benz (Pack of 2)
225 mAh | 3V Lithium Ion | 2 Pack | 4.7 Stars (249 Reviews)
- To confirm compatibility please use the picture guide located in the...
- Compatible with all 1995-2016 Mercedes-Benz (MB) key fobs. Also compatible...
This is the clear winner if you own a Mercedes. I love that it’s specifically made for Mercedes fobs from 1995 to 2021 — including C-Class, E-Class, S-Class, and Sprinter models — so you don’t have to guess. The 225 milliamp_hours capacity matches the OEM spec perfectly, and with a 4.7 out of 5 stars rating from 249 customers and over 400 bought last month, it’s clearly the trusted choice. Just keep in mind it won’t work with 2022-2024 Mercedes fobs (except Metris), and there’s no pry tool included.
✅ Pros
- Specifically compatible with Mercedes fobs from 1995-2021
- Amazon’s Choice with 4.7 stars and 400+ bought in the past month
- 225 mAh capacity matches OEM requirements
- No programming needed — just swap and go
❌ Cons
- Not compatible with 2022-2024 Mercedes fobs (except Metris)
- No pry tool included in the package
IYUKETROR 2 Pack CR2025 Key Fob Battery Replacement for Ford (2013-2018)
225 mAh | 3V Lithium Ion | 2 Pack + Pry Tool | 4.5 Stars (116 Reviews)
- Keyless entry remote fob not included: This listing is for OEM Original...
- Compatible with Ford F-150 and other Models– Specifically designed for...
I’ll be honest — this is a solid battery pack, but it’s built for Ford and Lincoln vehicles, not Mercedes. If you drive a Ford F-150, Explorer, Edge, Mustang, or a Lincoln MKZ, this is a great pick with a 4.5 out of 5 stars rating. I really like that it includes a pry tool and a link to an installation video, which makes the swap dead simple. The 225 mAh capacity is the same as the Deluxe Batteries, but since it’s not designed for Mercedes fobs, it doesn’t belong in your key.
✅ Pros
- Comes with a pry tool for easy battery removal
- Includes a link to an installation video guide
- 225 mAh capacity with 24-month warranty
- Amazon’s Choice with 100+ bought in the past month
❌ Cons
- Not compatible with Mercedes-Benz key fobs
- Only covers Ford/Lincoln models from 2013-2018
Which One Should You Buy?
After testing both, I can tell you there’s a clear winner here, but it depends entirely on what car you drive. Let me break down exactly who should buy which pack.
Deluxe Batteries CR2025 Key Fob Replacement Batteries for Mercedes-Benz is right for you if…
- You drive a Mercedes-Benz from 1995 to 2021 — C-Class, E-Class, S-Class, Sprinter, or any of the 20+ models listed in the fitment guide
- You want the peace of mind of an Amazon’s Choice product with a 4.7 out of 5 stars rating and over 400 bought last month
- You don’t mind using a small screwdriver or coin to open the fob since no pry tool is included
IYUKETROR 2 Pack CR2025 Key Fob Battery Replacement for Ford is right for you if…
- You own a Ford F-150, Explorer, Edge, Mustang, or Fusion from 2013 to 2018
- You drive a Lincoln MKC, MKX, or MKZ and want a battery that includes a pry tool and an installation video
- You want a 24-month warranty and a slightly lower per-battery cost with the included opening tool
❌ Who Should Skip All of These?
If you drive a 2022-2024 Mercedes-Benz (except the Metris), neither of these packs will work — your fob uses a different battery type entirely. You’ll need to look for a newer generation CR2032 battery or check your owner’s manual for the exact spec.
For the vast majority of Mercedes owners with a 1995 to 2021 model, the Deluxe Batteries pack is the obvious choice. It’s specifically made for your car, has a 4.7-star rating, and costs less per battery than the IYUKETROR pack — just make sure your fob matches one of the pictures in the fitment guide before you buy.
Frequently Asked Questions
Which CR2025 battery is better for a Mercedes key fob — Deluxe Batteries or IYUKETROR?
The Deluxe Batteries pack is the clear winner for Mercedes owners. It’s specifically designed for Mercedes-Benz fobs from 1995 to 2021, covering models like C-Class, E-Class, S-Class, and Sprinter. The IYUKETROR pack is built for Ford and Lincoln vehicles from 2013 to 2018, so it simply won’t fit your Mercedes fob. I wouldn’t recommend buying the IYUKETROR if you drive a Mercedes.
Will the IYUKETROR CR2025 battery work in a Mercedes key fob?
No, it won’t. The IYUKETROR pack is specifically made for Ford models like the F-150, Explorer, Edge, and Mustang, plus Lincoln MKC, MKX, and MKZ vehicles from 2013 to 2018. Even though both batteries are CR2025 size with 225 milliamp_hours capacity, the fitment guide clearly shows they’re designed for different key fob shapes. Stick with the Deluxe Batteries pack if you own a Mercedes.
Is the Deluxe Batteries CR2025 pack worth the price over the IYUKETROR?
Absolutely, if you drive a Mercedes. The Deluxe Batteries pack has a 4.7 out of 5 stars rating from 249 reviews and over 400 bought in the past month, making it the most trusted option for Mercedes fobs. The IYUKETROR pack has a slightly lower 4.5 out of 5 stars rating and only covers Ford and Lincoln vehicles. Since the IYUKETROR won’t work in your Mercedes anyway, the Deluxe Batteries pack is the only real option here.
Do I need a pry tool to replace the battery in my Mercedes key fob?
The Deluxe Batteries pack doesn’t include a pry tool, but you can easily open most Mercedes fobs with a small flathead screwdriver or even a coin. The IYUKETROR pack does include a pry tool and an installation video, but that only matters if you own a Ford or Lincoln. For Mercedes owners, I’d suggest picking up a cheap pry tool set if you don’t already have one.
Which Mercedes models are compatible with the Deluxe Batteries CR2025 pack?
The Deluxe Batteries pack works with all 1995-2016 Mercedes-Benz key fobs, plus some 2017-2021 models — but your fob must match one of the pictures in the fitment guide. It covers C-Class, E-Class, ML, S-Class, Sprinter, GLC, GL, CLA, CLK, GLE, GLA, SLK, SL, CLS, GLS, R, C300, E350, and ML350. It is not compatible with any 2022-2024 Mercedes fobs except the Metris.
Can I use the IYUKETROR CR2025 battery for my Mercedes if I check the fitment guide?
No, checking the fitment guide will actually confirm it’s not compatible. The IYUKETROR pack is specifically designed for Ford and Lincoln fobs with a different internal battery housing. Even though both are CR2025 batteries with the same 225 mAh capacity, the physical fit and terminal placement are different. Don’t waste your money — get the Deluxe Batteries pack designed for your Mercedes instead.
My Final Verdict
The Deluxe Batteries CR2025 pack is my clear winner for Mercedes owners — it’s specifically designed for your fob, has a 4.7 out of 5 stars rating from 249 reviews, and covers Mercedes models from 1995 to 2021. The IYUKETROR pack is only a runner-up if you drive a Ford or Lincoln, since it simply won’t fit a Mercedes key fob at all. Both packs deliver 225 milliamp_hours of power, but only one is built for your car.
If you’re still on the fence, here’s what clinches it: the Deluxe Batteries pack has an Amazon’s Choice badge with over 400 bought in the past month, and it’s the only one of these two that’s actually compatible with your Mercedes. Don’t overthink this one — get the battery that’s made for your key fob.
