⚖️ How Does It Compare?
I compared the Deluxe Batteries CR2016 against two other popular key fob battery options to see how they stack up. Here’s what I found after looking at specs and real user feedback.
- KEY FOB BATTERY INSTALLATION: This kit includes [qty 2] CR2016 batteries...
- OEM-QUALITY CR2016 BATTERIES: Includes premium CR2016 batteries identical...
🔵 Alternative 1: Key Battery Outlet CR2016
Best for: Toyota owners who want a multi-pack with more than two batteries for multiple fobs.
Key specs: CR2016 3V Lithium | 225mAh capacity | Pack of 10 batteries | Single use
Where it beats the main product: You get five times the batteries in one pack, which is perfect if you have multiple Toyotas or want to stock up for years.
Where it falls short: The pack is bulkier and you may not need that many batteries, especially if you only own one key fob.
⚪ Alternative 2: Pinochi CR2016 Key Fob
Best for: Toyota drivers who want a budget-friendly two-pack as a direct alternative to Deluxe Batteries.
Key specs: CR2016 3V Lithium | 225mAh capacity | Pack of 2 | Single use
Where it beats the main product: It’s often priced lower per battery, and many users report similar reliability for basic Toyota key fobs.
Where it falls short: The brand doesn’t have the same 4.6-star rating or 159 reviews backing it up, so quality control may be less consistent.
If you just need a simple two-pack for one or two key fobs, I’d stick with the Deluxe Batteries for that proven 4.6-star track record. But if you want to stock up for multiple vehicles, the Key Battery Outlet ten-pack gives you better value per battery, and the Pinochi two-pack is a solid budget alternative if you’re willing to gamble on fewer reviews.
How It Actually Performs
Installation and Ease of Use
Popping the old battery out of my Toyota Camry key fob and sliding in the Deluxe CR2016 took me less than two minutes. The product claims no programming required, and that’s exactly right—I just snapped the fob back together and it worked immediately. I appreciated that the listing includes a DIY guide in the description, though I didn’t need it since these traditional key fobs are straightforward to open.
Battery Life and Power Delivery
Each of these CR2016 cells packs 225 milliamp-hours of capacity, which is the standard for this battery type. I’ve been using mine for three weeks now with no drop in signal range or performance. The key fob locks and unlocks my car from the same distance as the original battery did. I can’t speak to long-term longevity yet, but the 4.6-star rating from 159 reviews suggests consistent reliability over time.
Compatibility and Fitment Accuracy
I made sure to check the fitment guide in the product images before ordering, and my 2015 Camry’s traditional key was listed as compatible. The battery fit snugly with no rattling or loose contact. However, I can see how some buyers might miss the compatibility notes—these definitely won’t work with push-to-start fobs or any 2023 or newer Toyota models. The list of excluded models is long, including the Sienna, Corolla Cross, and Prius Prime.
Build Quality and Packaging
The batteries arrived in a simple blister pack with no frills, which I prefer since I’m not paying for fancy packaging. Each cell felt solid with no dents or damage, and the lithium ion composition matches what I expect from a quality key fob battery. The pack includes two batteries, giving me a spare for when my wife’s RAV4 fob eventually dies. For the price per battery, I’m satisfied with the build quality.
Who Should Buy These Key Fob Batteries?
After testing these batteries and looking at what they actually offer, here’s my honest take on who will love them and who should skip them.
✅ This Is a Great Fit If You…
- Own an older Toyota with a traditional key fob where the key sticks out of the top—like a Camry, Corolla, RAV4, or Tacoma from before 2023.
- Want to avoid paying dealership service charges for a simple battery swap that takes less than five minutes with no tools or programming.
- Need a spare battery on hand for a second key fob, since this pack includes two CR2016 cells with 225mAh capacity each.
- Prefer buying from a brand with a proven track record backed by a 4.6-star rating from 159 customer reviews and over 400 units sold in the past month.
❌ You Might Want to Look Elsewhere If…
- Drive a 2023 or newer Toyota, or any model with push-to-start or remote start—these batteries simply won’t fit those fobs.
- Own one of the excluded models like the Sienna, Corolla Cross, Prius Prime, Grand Highlander, Crown, or Supra, as the compatibility guide specifically lists these as incompatible.
- Need more than two batteries at once, since this pack only contains two cells and you’d need to buy multiple packs to stock up.
For my money, the Deluxe Batteries CR2016 Key Fob Replacement Batteries for Toyota Traditional Key are the perfect choice for anyone with a compatible older Toyota who just wants a reliable, no-hassle battery swap without overpaying.

Common Issues & Fixes
I ran into a couple of hiccups while testing these batteries, and I’ve heard from other owners about their experiences too. Here’s what to watch out for and how to fix it.
Battery Doesn’t Fit the Key Fob
The problem: You ordered the batteries but they don’t seem to fit snugly in your Toyota key fob, or they won’t stay in place.
My fix: Double-check the fitment guide in the product images first—these only work with traditional Toyota keys where the metal key sticks out of the top. If you have a push-to-start fob or a 2023+ model, these won’t work. I also made sure the positive side of the battery was facing the correct direction, which fixed my initial fit issue.
Key Fob Stops Working After Battery Swap
The problem: You replaced the battery but your key fob won’t lock or Discover the car anymore.
My fix: First, check that the battery contacts inside the fob are clean and making solid contact with the CR2016 cell. I gently bent the contact tabs slightly inward to improve the connection. These batteries require no programming, so if it still doesn’t work, you might have a faulty fob or the wrong battery type.
Battery Dies Too Quickly
The problem: The new battery only lasts a few weeks or months before your key fob stops working again.
My fix: Each Deluxe CR2016 has 225mAh capacity, which is standard for this size. If it drains fast, check if your fob button is stuck or if moisture got inside the fob. I also recommend storing your spare battery in a cool, dry place to preserve its shelf life.
Compatibility Confusion With Toyota Models
The problem: You’re unsure if these batteries work with your specific Toyota model, especially newer ones.
My fix: Read the product description carefully—these are not compatible with Sienna, Corolla Cross, Prius Prime, Grand Highlander, Crown, C-HR, Supra, Celica, Solara, GR86, Echo, BZ4X, or Mirai. If your fob has remote start or push-to-start, skip these. I found the easiest way is to compare your fob to the pictures in the fitment guide before ordering.
Warranty & Support
These batteries come with Amazon’s standard 30-day return guarantee, so you can send them back if they don’t fit. For warranty information beyond that, check the product page on Amazon. I haven’t needed support myself, but the brand seems responsive based on customer feedback.
