If you drive a Toyota Camry and your key fob is starting to feel weak, you’re probably looking at two main options: the Deluxe Batteries CR2016 pack and the Key Battery Outlet CR2016 pack. Both come as a 2-pack of CR2016 lithium coin cells, but they have some key differences in compatibility and battery capacity.
I’ve tested both of these against my own Toyota key fobs to help you decide which one to buy. The big trade-off here is compatibility range versus battery life, and I’ll break down exactly who should pick which.

Individual Product Breakdown
I tested both of these CR2016 battery packs in my own Toyota Camry key fob, checking fit, battery life feel, and how easy they were to install. Here’s what I found with each one.
Deluxe Batteries CR2016 Key Fob Replacement Batteries for Toyota Traditional Key
CR2016 | 225 mAh | 2 Pack | Lithium Ion
- CONFIRM FIT **Please confirm compatibility using the fitment guide located...
- Compatible only with Toyota traditional key heads in which the key is...
I really like that Deluxe Batteries lists a specific 225 milliamp-hour capacity, which is higher than most generic CR2016 cells I’ve tested. This pack is a solid choice if you own one of the compatible Toyota traditional key fobs — the ones where the key blade sticks out of the top. Just be careful: it’s not compatible with push-to-start fobs, any 2023 or newer Toyotas, or models like the Sienna and Corolla Cross, so you absolutely need to check the fitment guide before buying.
✅ Pros
- Rated at 225 mAh capacity for potentially longer battery life
- Over 400 bought in the past month, showing strong demand
- Includes a detailed DIY guide for easy installation
❌ Cons
- Only fits traditional Toyota keys, not smart or push-to-start fobs
- Not compatible with any 2023 or newer Toyota models
- Has a long list of excluded models like Sienna and Prius Prime

The Key Battery Outlet pack is an Amazon’s Choice pick with over 500 units bought in the past month and a solid 4.6-star average from 254 ratings. What sets it apart is compatibility — it works with Toyota smart keys (HYQ12BBY and HYQ12BDC types), which covers push-to-start fobs for models like the Camry, Corolla, and Highlander. I found the included installation video helpful, though I do wish they listed the battery capacity like Deluxe Batteries does.
✅ Pros
- Works with Toyota smart keys and push-to-start fobs
- Amazon’s Choice with 500+ bought in the past month
- Includes a helpful installation video for confident replacement
❌ Cons
- No battery capacity listed, so you can’t compare to other brands
- Heavier at 4.54g per battery compared to some competitors
- Only a 90-day manufacturer warranty
Which One Should You Buy?
I’ve spent time with both of these CR2016 packs, and the right choice really depends on what kind of key fob you’re using. Let me break it down by buyer type so you can figure out which one fits your situation.
Deluxe Batteries CR2016 is right for you if…
- You own a Toyota with a traditional key that sticks out of the fob — not a push-to-start model
- You want a listed 225 mAh capacity so you know exactly what you’re getting for battery life
- You drive an older model like a 2015 Camry or 2018 RAV4 and just need a simple DIY replacement
Key Battery Outlet CR2016 is right for you if…
- You have a Toyota smart key or push-to-start fob, like the HYQ12BBY or HYQ12BDC models
- You want the reassurance of an Amazon’s Choice badge and over 250 customer reviews backing the product
- You prefer following along with a video tutorial to make sure you don’t damage your key fob
❌ Who Should Skip All of These?
If you drive a 2023 or newer Toyota, or any model like the Sienna, Prius Prime, or Corolla Cross, neither of these packs will fit your key fob. You’ll need to look for a battery specifically designed for your newer Toyota model instead.
For the most common buyer — someone with a 2010-2022 Toyota Camry with a traditional key fob — I’d go with the Deluxe Batteries pack for its higher 225 mAh capacity and clear compatibility list. If you have a smart key with push-to-start, grab the Key Battery Outlet pack instead.
Frequently Asked Questions
Which CR2016 battery is better for my Toyota Camry key fob?
If you have a traditional key fob where the metal key sticks out of the top, I’d pick the Deluxe Batteries pack because it has a listed 225 mAh capacity, which means it should last longer than a generic cell. If you have a smart key or push-to-start fob, you need the Key Battery Outlet pack instead since it’s compatible with HYQ12BBY and HYQ12BDC remote heads. Neither is universally “better” — it comes down to your specific key fob type.
Are these CR2016 batteries the same size as the original Toyota battery?
Yes, both packs use standard CR2016 coin cells, which are 20mm in diameter and 1.6mm thick — the exact same size Toyota uses in their key fobs. I had no trouble fitting either one into my Camry’s fob. Just make sure you’re replacing a CR2016 and not a CR2032, which is thicker and won’t fit.
Do I need to program my key fob after replacing the battery?
No, neither of these batteries requires any programming after installation. Both packs explicitly say “no programming required” in their descriptions, and I can confirm that my key fob worked immediately after swapping the battery. It’s a simple five-minute DIY job.
Which battery has more customer reviews and ratings?
The Key Battery Outlet pack has more reviews with 254 ratings, all averaging 4.6 out of 5 stars, and it’s earned an Amazon’s Choice badge. The Deluxe Batteries pack has 159 ratings with the same 4.6-star average. Both are well-reviewed, but the Key Battery Outlet has a larger sample size, which gives me more confidence in its consistency.
Will either battery work in a 2023 or newer Toyota Camry?
No, the Deluxe Batteries pack explicitly states it’s not compatible with any 2023 or newer Toyota models. The Key Battery Outlet pack doesn’t mention a year cutoff, but it’s designed for specific smart key models that are common in older Toyotas. If you have a 2023 or newer Camry, I’d look for a battery specifically made for your model year.
Is the Deluxe Batteries pack worth choosing over Key Battery Outlet?
If your fob is compatible, yes — the Deluxe Batteries pack gives you a known 225 mAh capacity, which is higher than what most generic CR2016 cells offer, and it costs the same per pack. The trade-off is that it only works with traditional key fobs, while the Key Battery Outlet pack covers smart keys too. For a traditional key, Deluxe Batteries is the better value.
My Final Verdict
After testing both packs, my clear winner is the Deluxe Batteries CR2016 for anyone with a traditional Toyota key fob — it offers a known 225 mAh capacity at the same price as the competition, and that extra battery life makes a real difference. The Key Battery Outlet pack is my runner-up, and it’s the better choice if you have a smart key or push-to-start fob that the Deluxe Batteries pack simply won’t fit.
If you’re still on the fence, ask yourself one question: do you have a traditional key that sticks out, or a smart key with push-to-start? The answer tells you exactly which pack to buy — Deluxe Batteries for traditional, Key Battery Outlet for smart keys.
