Best Battery For Key Fob: Compare 10 Coin-Cell Options

#1 · Best Overall

1. Duracell CR2032

• Voltage: 3 V
• Battery Capacity: 1500 milliamp hours
• Weight: 18.14 g

Best for: CR2032 for family key fobs.

Why it ranks #1: A four-count CR2032 pack is explicitly listed for key fobs, with 3V output, 1,500mAh listed capacity and a bitter coating on both sides.

A bitter coating on both sides is the Duracell CR2032’s distinguishing safety feature, helping deter young children from swallowing a coin cell. Its 3V CR2032 format also serves many car key fobs and other small electronics, making this four-count option relevant when a household has several compatible devices.

The CR2032 designation and 3V output identify the cell type for key fobs and devices such as AirTags, fitness trackers, glucose monitors, and tire pressure sensors. That range can make one battery type useful across household electronics, though each device must call for CR2032. The coating on both sides adds a deterrent in homes with young children, while the stated 10-year storage guarantee can help when keeping spare cells for later replacement.

Skip it if you need a CR2016 or CR2450 cell; this CR2032 is a different battery size.

A good match for households replacing CR2032 key-fob cells and keeping spares for other listed electronics. The two-sided bitter coating is useful around young children, but the cell is not a substitute for other coin-cell sizes.

#2 · Child Safety Features

2. Energizer 2032

• Voltage: 3 V
• Battery Capacity: 240 milliamp hours
• Weight: 18.14 g

Best for: Child-alert 2032 replacement.

Why it ranks #2: This four-pack supplies 3V CR2032 cells with a listed 240mAh capacity; its described child-safety features include a bitter coating and Color Alert.

Energizer’s Color Alert technology is the clearest differentiator: the listing says it dyes the mouth blue seconds after contact with saliva to help alert caregivers to possible ingestion. The 3V 2032 coin cells also serve buyers seeking replacements for compatible key fobs and other devices.

The 3V 2032 format identifies this four-pack for devices specifying that coin-cell type, including compatible fobs. Its listed 240mAh capacity provides a concrete specification for buyers comparing cells, while the Child Shield combines Color Alert, a bitter coating, and secure packaging on select packs. That combination focuses the product on households attentive to battery safety; the packaging feature is not stated to be present on every pack, so the Color Alert and coating are the more consistent listed points.

Skip it if you require confirmed secure packaging; the listing says that feature appears only on select packs.

A suitable option for a buyer replacing compatible 2032 fob cells who values the listed Color Alert and bitter coating. Secure packaging is not assured on every pack, and the 2032 format will not fit devices requiring another cell size.

#3 · Largest Pack

3. Amazon Basics CR2032

• Voltage: 3 V
• Battery Capacity: 225
• Weight: 4.54 g

Best for: Multi-device CR2032 spares.

Why it ranks #3: The 10-pack offers CR2032 cells for key fobs, 3V output and a listed 225mAh capacity, making it the largest included quantity here.

Ten CR2032 cells make the Amazon Basics pack useful for buyers replacing several key-fob batteries or keeping a supply for other small electronics. The listing also names watches, calculators, and Apple TV remotes, so its appeal extends beyond automotive use when those devices call for this 3V coin-cell type.

The 3V CR2032 specification supports choosing the right cell type for compatible fobs and the listed watches, calculators, and Apple TV remotes. A ten-cell quantity means replacements can be kept on hand for multiple devices, while model engraving helps identify the cell when sorting spares. The listing also names BR2032, DL2032, and ECR2032 as replacement designations; buyers should still follow the battery type specified by each device.

Skip it if you want a bitter-coated cell for a home with young children; Duracell 2032 has coating on both sides.

A practical choice for someone maintaining several CR2032 devices or wanting clearly marked spares. Its wide listed device range and ten-cell supply suit mixed electronics, while buyers prioritizing a bitter coating should choose a different option.

#4 · Chevy GMC Fit

4. Deluxe Chevy GMC CR2032

• Voltage: 3 V
• Battery Capacity: 225 milliamp hours

Best for: Chevy and GMC fob replacement.

Why it ranks #4: This two-pack is specifically listed as a Chevy and GMC key fob replacement and identifies its included cells as CR2032, 3V batteries.

Chevy- and GMC-specific positioning gives this two-cell Deluxe Batteries pack a focused use case: replacing a CR2032 in a compatible vehicle fob. The listing says its cells come from the manufacturer used by Chevrolet and GMC, a detail aimed at owners seeking an OEM-source replacement rather than a general-purpose coin-cell multipack.

The CR2032 designation and 3V specification establish the battery type and voltage for compatible fobs, while the stated Chevy and GMC focus narrows the intended audience. Deluxe Batteries says the cells are sourced from the same manufacturer used by Chevrolet and GMC, connecting the sourcing claim to its OEM-replacement positioning. With two cells included, owners have a second replacement on hand, but the listing directs buyers to check its fit guide before selecting the pack.

Skip it if you need a general-purpose CR2032 pack; Amazon Basics CR2032 10-Pack lists watches, remotes, and calculators too.

Consider this pack if you own a Chevy or GMC and want a two-cell CR2032 replacement with the stated automaker-manufacturer sourcing. Its focused vehicle coverage makes it less suitable for buyers seeking a broadly described multipurpose pack.

#5

5. Lucrum Chevy GMC CR2032

• Battery Capacity: 240 milliamp hours

Best for: GMC and Chevy model coverage.

Why it ranks #5: The two-pack is listed for compatible GMC and Chevy fobs and specifies CR2032, 3V cells with a 240mAh capacity; model-year fit still matters.

Lucrum names GMC and Chevy models across multiple years, including Acadia, Canyon, Sierra, and Yukon, making its two-cell CR2032 pack useful for owners checking a specific fob replacement. The listed 240mAh capacity and 3V coin-cell format add concrete specifications to that vehicle-focused compatibility pitch.

The GMC and Chevy model list gives owners a way to compare their vehicle with the stated coverage, while the CR2032 and 3V details identify the required battery type. A 240mAh capacity is also specified, and two cells are included for a replacement plus a spare. Lucrum notes that key fobs can vary by model year and advises checking that the fob uses CR2032, so the vehicle list and actual cell type both matter before installation.

Skip it if you need a broad household multipack; Amazon Basics CR2032 10-Pack lists several non-automotive devices and includes ten cells.

A relevant choice for GMC or Chevy owners whose model and fob battery type match the listing. Its named vehicle coverage is helpful, but year variation means checking the specific fob’s CR2032 requirement remains important.

#6 · General CR2032 Fit

6. Deluxe Universal CR2032

Best for: Automaker-sourced universal CR2032.

Why it ranks #6: Its two included CR2032 replacements are described for car key fobs generally, though the listing provides fewer specific fit details than vehicle-targeted options.

Deluxe Batteries positions this two-cell CR2032 pack around sourcing from the same manufacturer used by automakers, making it relevant to drivers seeking a broadly marketed key-fob replacement. The title calls it universal fit, while the product details describe it as a replacement for car key fobs rather than a multi-device battery assortment.

The CR2032 designation gives buyers a specific coin-cell type to compare with the battery called for by their fob, and the two-cell quantity leaves one replacement available after the first change. Deluxe Batteries says the cells come from the same trusted manufacturer used by automakers and are supplied from its USA-based facility. Those claims support the product’s OEM-replacement positioning, but the listing does not enumerate vehicle makes or models, so its universal-fit wording is not a detailed fit list.

Skip it if you need a named vehicle fit list; Lucrum 2PCs CR2032 lists GMC and Chevy model coverage.

This pack suits a driver whose fob calls for CR2032 and who values the stated automaker-supplier sourcing. Because the listing gives no vehicle-by-vehicle coverage, buyers who need an explicit make and model match may prefer a more specific fit listing.

#7

7. HIVEVOLT Nissan CR2032

• Voltage: 3 V

Best for: Nissan model-specific fob cells.

Why it ranks #7: This two-pack lists 3V CR2032 cells and Nissan compatibility across multiple models, including Altima, Rogue and Sentra; confirm the fob and model year.

A long list of Nissan nameplates and model years makes HIVEVOLT’s two-pack a targeted option for owners replacing a Nissan key-fob battery. The listing names models including Altima, Rogue, Sentra, and Pathfinder, giving buyers a vehicle-focused starting point instead of presenting the cells as an unrestricted universal replacement.

The 3V CR2032 specification identifies the coin-cell type, while the extensive Nissan compatibility list helps owners narrow whether the pack suits their vehicle. The title names models such as Altima, Versa, Pathfinder, Rogue, Sentra, Murano, and Leaf, and the features provide model-year ranges for several entries. Two batteries are included, leaving a spare after replacement. Since vehicle coverage varies by model and year, the listed compatibility details matter more than the broad Nissan label alone.

Skip it if you drive a Chevy or GMC; Deluxe Batteries Key Fob Replacement Batteries for Chevy & GMC targets those fobs.

A sensible shortlist candidate for Nissan owners whose vehicle appears in the supplied compatibility details and calls for CR2032. The model and year coverage is the key boundary, so owners of other makes should choose a differently targeted option.

#8

8. Key Battery Outlet CR2032

• Voltage: 3 V
• Weight: 2.9 g

Best for: Basic CR2032 vehicle replacement.

Why it ranks #8: The two-pack contains 3V CR2032 cells and is listed for passenger cars, trucks and vans, but provides no specific vehicle-model fit guide.

Passenger cars, trucks, and vans are all named in Key Battery Outlet’s vehicle compatibility details, giving this two-cell CR2032 pack a straightforward automotive focus. The USA-based company says it partners with official distributors and sources its premium batteries from the provider used by official car brands.

The CR2032 size and 3V voltage give buyers the core specifications to compare with a vehicle fob’s required cell. Its listed passenger-car, truck, and van compatibility supports an automotive replacement use, while the two-cell quantity supplies a second battery for later use. The company’s distributor and sourcing statements explain its OEM-oriented positioning, but no vehicle makes or model years are enumerated in the supplied details, leaving the buyer without a model-by-model fit list.

Skip it if you need named Chevy and GMC fit details; Lucrum 2PCs CR2032 lists models and year ranges.

This suits a buyer whose fob calls for CR2032 and who wants a small two-cell automotive replacement pack. The broad vehicle categories and sourcing claim are useful context, but the listing does not specify individual makes or model years.

#9

9. Duracell CR2016

• Voltage: 3 V
• Battery Capacity: 1
• Weight: 9.07 g

Best for: CR2016 fob and remote cells.

Why it ranks #9: This two-count, 3V CR2016 pack is listed for car key fobs, but suits only remotes that specifically require the smaller CR2016 size.

The CR2016 size distinguishes this Duracell pack from the many CR2032 options, making it relevant when a key fob specifically calls for the thinner 2016 cell. The listing also names car remotes, watches, and medical devices, while its child-safety features add a household consideration for coin-cell storage.

The 3V CR2016 specification is the essential fit point: it serves compatible fobs and listed devices, but is not a substitute for a CR2032. Duracell describes child-safety design and the supplied facts specify bitter coating on both sides and child-safe packaging, which may matter when storing spares around children. The two-cell pack can cover a replacement and another compatible device, while the stated device range includes remotes, fitness trackers, and calculators.

Skip it if you need a CR2032 cell; Duracell 2032 CR2032 4 Count is the matching size option.

Choose this for a fob or other device that specifically calls for CR2016, especially if the listed child-safety features matter at home. Its distinct cell size is a strict fit boundary, not an interchangeable alternative to CR2032.

#10

10. Duracell CR2450

• Voltage: 3 V
• Battery Capacity: 620 milliamp hours
• Weight: 17.01 g

Best for: High-capacity CR2450 devices.

Why it ranks #10: The single 3V CR2450 cell has a listed 620mAh capacity and is described for key fobs, but fits only remotes requiring CR2450.

A stated 620mAh capacity sets this Duracell CR2450 apart among the listed coin cells, while its 3V output suits devices that specifically require the 2450 size. The listing names key fobs, watches, car remotes, medical devices, and security devices, alongside child-resistant packaging.

The CR2450 designation is the crucial compatibility point for fob owners: the cell fits only devices specifying this size, not fobs that take CR2032 or CR2016. Its 620mAh capacity and 3V voltage offer concrete specifications for buyers comparing replacement cells. Duracell also lists child-resistant packaging, a practical consideration when storing the single included battery in a home with children. The product’s device range extends beyond fobs to watches and security electronics.

Skip it if you need a two-cell CR2032 pack; Amazon Basics CR2032 10-Pack supplies that different cell size in greater quantity.

A fit for someone whose key fob or other device specifically requires CR2450 and who values the stated capacity and child-resistant packaging. The single-cell quantity and distinct size make it unsuitable as a general CR2032 spare pack.
