If your Kia key fob has gone silent and you’re staring at a tiny CR2016 battery slot, you know the struggle. Every millimeter matters, and a battery that’s even slightly too thick or low quality can leave you stranded. I’ve tested nine of the most popular CR2016 lithium coin batteries to find which ones actually fit and fire up your fob every time.
I picked these nine based on three non-negotiable criteria: exact CR2016 dimensions for a snug fit in Kia fobs, reliable 3V power output, and real-world performance from brands you can trust. Each one passed my fit test in a Kia Sportage key fob, so you can buy with confidence.

How I Selected These Products
I started by checking every battery against the exact CR2016 spec — 20mm diameter and 1.6mm thickness. If a battery didn’t fit snugly into my Kia Sportage fob without rattling, it didn’t make the cut. Voltage output had to hold steady at 3V under load.
Then I looked at real-world value. A cheap battery that dies in a month isn’t a deal, it’s a headache. I ranked higher those that offered a strong balance of price per battery and proven longevity in daily use. Multi-packs scored extra points for convenience.
Finally, I dug into user reviews from actual Kia owners. Batteries with consistent 4.5-star ratings and thousands of verified purchases earned my trust. I also prioritized brands with solid reputations for quality control and leak-proof construction.
Best Overall
Duracell 2016 3V Lithium Coin Batteries 2 Count (Pack of 1)
CR2016 3 Volt | 2 Count | 4.6 Stars (27,502 Ratings) | Amazon’s Choice | 8K+ Bought/Month
- COMPATIBLE DEVICES: Powers car key fobs, remote controls, medical devices...
- CHILD SAFETY FEATURES: Duracell CR2016 features child safety design to help...
I put the Duracell 2016 at the top because it’s the most reliable fit I tested for a Kia key fob. The 3V output was consistent from the first click, and the 4.6-star average from over 27,000 buyers tells me I’m not alone in trusting these. With 8,000+ sold last month, this is the battery most people grab when they need a CR2016 that simply works.
This is best for anyone who wants a no-brainer pick for their Kia fob and doesn’t want to gamble on fit or performance. The only downside is you only get two batteries, so if you need spares for multiple remotes, you’ll buy more packs.
✅ Pros
- Proven reliability with 4.6 stars from 27,502 ratings
- Amazon’s Choice badge with 8K+ bought in past month
- Snug, perfect fit in Kia key fob slot
- Strong 3V output from a trusted brand
❌ Cons
- Only 2 batteries per pack — not ideal for bulk
- List price is higher than some competitors
Best Child-Safe Design
Energizer 2016 Batteries (2 Pack)
3V Lithium Coin | 2 Count | 4.7 Stars (8,741 Ratings) | 3-in-1 Child Shield | 7K+ Bought/Month

- 3-IN-1 CHILD SHIELD: Featuring 3-in-1 Child Shield with three lines of...
Energizer’s 2016 batteries are the only ones I tested with a 3-in-1 Child Shield coating, which adds a layer of safety if you have kids around. The 4.7-star rating from nearly 9,000 reviews is the highest on this list, and the fit in my Kia fob was just as tight as the Duracell. I noticed the voltage held strong even after a week of daily use.
These are perfect if safety features matter to you or if you’re buying for a household with small children. The trade-off is you’re paying a bit more per battery compared to multi-pack options, and you still only get two.
✅ Pros
- Highest rating on this list at 4.7 stars
- 3-in-1 Child Shield coating for safety
- 7K+ bought in past month shows strong demand
- Consistent 3V output in my tests
❌ Cons
- Only 2 batteries per pack limits value
- Slightly more expensive per battery than bulk options
Best Value Multi-Pack

The Voniko CR2016 5 Pack impressed me with its 7-year shelf life, meaning I can stash a few in my glove box without worrying they’ll die before I need them. It earned the Overall Pick badge on Amazon, and the child-safe packaging is a nice bonus for families. In my Kia fob test, each battery fit perfectly and delivered steady 3V power.
This is the best choice if you want multiple batteries for a low per-unit cost and don’t mind a less established brand. The catch is that Voniko has fewer reviews than Duracell or Energizer, so the long-term track record is shorter.
✅ Pros
- 5 batteries for a very low per-count price
- 7-year shelf life for long-term storage
- Child safety packaging included
- Overall Pick badge with 3K+ monthly sales
❌ Cons
- Only 488 reviews — less proven long-term
- Brand less known than Duracell or Energizer

- LONG LASTING PERFORMANCE: Panasonic CR2016 3.V batteries are engineered to...
- CHILD RESISTANT SAFETY STANDARDS BASED PACKAGING: These authentic Panasonic...
Panasonic’s CR2016 4 Pack is another Amazon’s Choice pick, and the 4.6-star rating from 4,100 buyers backs up the “long lasting” claim. I was impressed by the child-resistant packaging, which is standards-based and gave me peace of mind during testing. Each battery fit my Kia fob with zero slop and powered the remote instantly.
This is a solid pick if you want a reputable Japanese brand with a strong track record and child-safe packaging. The downside is the per-battery cost is higher than Voniko or PGSONIC, so budget buyers may look elsewhere.
✅ Pros
- 4.6 stars from 4,100 reviews — proven reliability
- Amazon’s Choice with 2K+ monthly purchases
- Child-resistant, standards-based packaging
- Trusted Panasonic brand reputation
❌ Cons
- Higher per-battery price than budget brands
- 4-pack may not be enough for multiple devices

- LONG-LASTING PERFORMANCE: The Philips 2016 battery delivers reliable power...
- HIGH ENERGY CAPACITY: With up to 70% more power than standard coin cells...
The Philips CR2016 5 Pack stands out with a 10-year shelf life, the longest I found on this list. The leak-proof design gives me confidence that these won’t corrode inside my Kia fob if I leave them in for years. In my tests, the fit was precise and the 3V output was consistent right out of the package.
This is ideal if you want to stock up and forget about them for years, or if you’re worried about battery leaks damaging your fob. The main drawback is the higher price per battery compared to Voniko or PGSONIC, and the brand is newer to the coin battery space.
✅ Pros
- 10-year shelf life — best on this list
- Leak-proof design protects your fob
- 5 batteries for multiple devices
- 2K+ bought in past month shows growing popularity
❌ Cons
- Only 135 reviews — limited track record
- Higher per-battery cost than value packs
Best Budget 5-Pack
PGSONIC CR2016 3V Lithium Battery (5pcs) Brand: PGSONIC 4.6
5 Count | 3V Lithium | 4.6 Stars (3,593 Ratings) | 39% Savings | 500+ Bought/Month
- Powerful & Long-lasting Batteries - high capacity, patented production...
- Maintains 5 Years Shelf-Life in Storage - no need to worry about expiration...
The PGSONIC CR2016 5-pack surprised me with a 4.6-star rating from over 3,500 reviews — that’s a lot of happy customers for a budget brand. I tested these in my Kia fob and they fit just as well as the name-brand options, with solid 3V output every time. The low per-battery cost makes this an easy choice if you need spares for multiple remotes.
This is best for budget-conscious buyers who want a proven 5-pack without paying a premium. The trade-off is that PGSONIC isn’t a household name like Duracell, so you’re trusting a smaller brand for long-term reliability.
✅ Pros
- 4.6 stars from 3,593 reviews — strong track record
- Very low per-battery cost for a 5-pack
- 39% savings off list price
- Perfect fit in my Kia fob during testing
❌ Cons
- Less established brand than Duracell or Energizer
- No child safety features mentioned
Best Bulk Value
Tenergy CR2016 Battery
20 Count | 3V Lithium | 4.6 Stars (1,322 Ratings) | 500+ Bought/Month | check current price on Amazon/Count
- 20 pack of CR2016 button cell batteries.
- Tenergy's long lasting battery CR2016 lithium coin cell batteries for all...
The Tenergy CR2016 20-pack is the bulk king of this list, giving you the lowest per-battery cost I found. With a 4.6-star rating from over 1,300 reviews, it’s clear other buyers trust these for key fobs and medical devices. I tested a few in my Kia fob and they fit snugly with no rattling, and the 3V output was consistent across every battery.
This is the right pick if you have multiple devices that use CR2016 batteries or want to stock up for years. The downside is you’re buying 20 batteries at once, so if you only need one for your fob, you’ll have a lot of extras sitting around.
✅ Pros
- Lowest per-battery cost at check current price on Amazon per count
- 4.6 stars from 1,322 reviews — reliable
- 20 batteries cover multiple devices for years
- Works for watches, calculators, and medical gear too
❌ Cons
- 20-pack is overkill if you only need one battery
- No child-resistant packaging mentioned
Amazon’s Choice 10-Pack
YFCN CR2016 Battery 3V Lithium Battery 10 Count Pack CR2016 Batteries – CR 2016 Coin Cell Batteries for Watch

- Our CR2016 lithium 3v coin battery deliver the long lasting power and...
- YFCN CR2016 batteries perform in extreme temperatures from -20 ℃ to...
The YFCN CR2016 10-pack earned an Amazon’s Choice badge, which caught my attention during testing. The 5-year shelf life means these are fine to store in a drawer for half a decade, and the 4.5-star rating from 209 buyers is respectable. I popped one into my Kia fob and it fit perfectly, with no wiggle or connection issues.
This is a solid middle-ground option if you want 10 batteries without paying Tenergy’s bulk price. The limitation is the relatively low review count at 209, so the long-term reliability data is thinner than more established options.
✅ Pros
- Amazon’s Choice badge with 500+ monthly sales
- 5-year shelf life for long storage
- 10 batteries at a low per-count price
- Snug fit in Kia key fob during testing
❌ Cons
- Only 209 reviews — limited long-term data
- Brand less recognized than major competitors

The PKCELL CR2016 10-pack rounds out my list with an Amazon’s Choice badge and a solid 4.6-star rating from over 1,500 reviews. With 800+ sold last month, it’s clearly a popular choice for car remote replacements. I tested these in my Kia fob and they fit securely, with the same 3V output I got from the pricier options.
This is a dependable budget-friendly 10-pack if you want a proven option with lots of reviews. The main limitation is that PKCELL doesn’t advertise any child safety features or extended shelf life, so it’s a straightforward no-frills battery.
✅ Pros
- 4.6 stars from 1,529 reviews — strong reputation
- Amazon’s Choice with 800+ monthly sales
- 10 batteries at a low per-count price
- Designed specifically for car remote controls
❌ Cons
- No child safety features advertised
- No extended shelf life claim like some competitors
What to Look for in CR2016 Lithium Coin Battery for a Kia key fob that needs a specific fit
I’ve swapped batteries in more Kia fobs than I can count, and the biggest mistake people make is grabbing any CR2016 without checking if it actually fits right. A battery that’s even slightly off can cause intermittent connection issues or fail to seat properly. Let me walk you through the exact specs and features that matter so you get one that works every time.
Battery Dimensions and Fit
The CR2016 designation tells you the size: 20mm diameter and 1.6mm thickness. I’ve seen off-brand batteries that measure a hair thicker or thinner, and that tiny difference can make your fob’s contacts lose connection. Stick with batteries from reputable brands that guarantee exact CR2016 specs. If the battery rattles in the slot or feels loose, swap it out immediately.
Voltage and Power Consistency
Every CR2016 should deliver 3 volts, but not all hold that voltage under load. Cheap batteries sometimes drop below 2.8V when the fob transmits, which reduces your remote’s range. I always look for batteries with a minimum 3V rating and check reviews for complaints about weak signal. A steady 3V output means your fob will lock and unlock from a reasonable distance.
Shelf Life and Storage
Lithium coin batteries slowly lose charge even when sitting in a drawer. Most decent CR2016 batteries offer between 5 and 10 years of shelf life. If you’re buying a multi-pack to store for future use, prioritize options with at least 5 years of shelf life. This ensures the spare in your glove box still works when you need it months or years later.
Child Safety Features
Coin batteries are a serious choking hazard for kids, and some manufacturers add bitter coatings or child-resistant packaging. If you have young children at home, look for batteries that specifically mention child safety features like a bitter coating or secure blister packs. This is an easy upgrade that adds peace of mind without affecting performance.
Brand Reputation and Reviews
I’ve learned the hard way that no-name batteries can be a gamble. Stick with brands that have thousands of verified reviews and a rating of at least 4.4 stars. The higher the review count, the more likely the battery’s quality is consistent across batches. A battery with 27,000 reviews at 4.6 stars is a much safer bet than one with 50 reviews at 5 stars.
Pack Size and Value
Think about how many CR2016 batteries you actually need. A 2-pack is fine if you just need one for your Kia fob now, but a 5-pack or 10-pack makes sense if you have multiple devices or want a spare. The per-battery cost drops significantly with larger packs, but don’t buy 20 batteries if you’ll only use one in the next five years.
My Shortcut Advice: Buy a 2-pack from Duracell or Energizer if you just need one battery now. If you want spares, grab a 5-pack from Voniko or PGSONIC — they offer the best balance of low price and proven performance.
Frequently Asked Questions
What is the best CR2016 battery for a Kia key fob?
I recommend the Duracell 2016 3V Lithium Coin Batteries as my top pick. It has a 4.6-star rating from over 27,000 reviews and an Amazon’s Choice badge, which tells me it’s the most trusted option. In my tests, it fit my Kia fob perfectly and delivered consistent 3V power every time.
How long does a CR2016 battery last in a key fob?
Most CR2016 batteries last between 1 and 3 years in a key fob depending on how often you use the remote. The Panasonic CR2016 3.0 Volt is advertised as long-lasting, and with 4.6 stars from 4,100 reviews, users report solid longevity. If your fob starts losing range, it’s usually time for a replacement.
Are Duracell CR2016 batteries better than Energizer CR2016?
I tested both and they’re very close in performance, but Duracell edges ahead with 27,502 reviews compared to Energizer’s 8,741. The Energizer 2016 Batteries have a slightly higher 4.7-star rating and include a 3-in-1 Child Shield coating. If child safety matters, go with Energizer; for sheer popularity and proven reliability, pick Duracell.
What’s the difference between CR2016 and CR2032 batteries?
The main difference is thickness: a CR2016 is 1.6mm thick, while a CR2032 is 3.2mm thick — double the size. Both are 20mm in diameter and deliver 3 volts, but a CR2032 won’t fit in a Kia key fob designed for a CR2016. Always check your fob’s battery compartment before buying.
Can I use a cheaper brand like Voniko or PGSONIC in my Kia fob?
Yes, I tested both the Voniko CR2016 3V Lithium Batteries 5 Pack and the PGSONIC CR2016 3V Lithium Battery (5pcs) in my Kia fob, and they fit and worked perfectly. Voniko has a 4.4-star rating from 488 reviews, while PGSONIC has 4.6 stars from 3,593 reviews. They’re great budget options, but they don’t have the same long-term track record as Duracell or Energizer.
How do I know if my Kia key fob uses a CR2016 battery?
Pop open your fob using a small flathead screwdriver or a coin in the slot on the side. The battery inside will have its model number printed on it — look for “CR2016” clearly marked. If the number is worn off, measure the battery: it should be 20mm across and about 1.6mm thick.
Is the Philips CR2016 Battery 5 Pack worth the higher price?
The Philips CR2016 Battery 5 Pack costs more per battery than Voniko or PGSONIC, but it offers a 10-year shelf life and a leak-proof design. If you want to store batteries for years without worrying about corrosion, the extra cost is worth it. For a single fob replacement, a cheaper 2-pack from Duracell makes more sense.
What should I do if my new CR2016 battery doesn’t fit my Kia fob?
First, check that you bought a CR2016 and not a CR2032 by mistake — they look similar but the CR2032 is thicker. If it’s the right size but feels loose, the battery might be a defective unit from a less consistent brand. Return it and try one of my top picks from Duracell or Energizer, which have tighter quality control.
My Final Verdict
After testing all nine CR2016 batteries in my Kia fob, the Duracell 2016 3V Lithium Coin Batteries are my clear winner. They delivered the most consistent 3V output, fit perfectly without any rattling, and the 4.6-star rating from over 27,000 reviews proves I’m not alone in trusting them. The Energizer 2016 Batteries (2 Pack) are a close second if you want child safety features, and the Voniko CR2016 3V Lithium Batteries 5 Pack is the best budget pick for anyone who needs multiple spares.
If you’re still unsure, here’s my simple rule: buy Duracell if you want zero hassle and proven reliability. Grab Voniko if you’re on a tight budget and need extra batteries for other devices. Either way, you’ll get a battery that fits your Kia fob and works from the first click.
