The key fob for a 2014 Honda Civic uses a CR2032 3-volt lithium coin cell. This is the standard size for most Honda remotes from that era and is widely available at auto parts stores and electronics retailers.
Battery type and compatibility
In 2014, Honda's remote entry system typically uses a CR2032 coin cell across its standard three-button remotes and the smarter entry fob. The battery sits in a small compartment, and the correct orientation is with the plus (+) side facing up when you install it. If your vehicle has a different configuration, consult the owner’s manual or check the fob label for the exact battery specification.
Replacement steps
To replace the battery, you generally need only a small tool or a coin to pry the case apart and a new CR2032 coin cell. Follow these steps to swap in a fresh battery:
- Use a coin or small flat tool to twist open the fob’s back cover along the seam and lift it off.
- Carefully remove the exhausted battery from its contacts.
- Insert a new CR2032 with the positive (+) side facing up, ensuring it sits flat and aligned.
- Snap the back cover back onto the fob until it clicks securely.
- Test the fob by locking/unlocking the doors or using the panic button to confirm proper operation.
After replacing, if the fob still doesn’t work, the issue may lie with the vehicle’s receiver or programming, and a dealer or automotive locksmith can help.
Where to buy and approximate cost
CR2032 batteries are widely available from a range of retailers. If you’re shopping for the replacement, consider these sources:
- Local auto parts stores (e.g., AutoZone, O'Reilly) that stock CR2032 coin cells in their battery sections.
- Honda dealer parts departments, which can provide the exact OEM accessory and guidance.
- Online retailers and battery specialty sites, which offer quick shipping and bulk options.
Typical prices for a single CR2032 battery range from about $2 to $6, depending on brand and supplier.
Additional notes and safety tips
Smart entry vs standard remote
For 2014 Civics, both the standard remote and the smart-entry fob generally use the same CR2032 battery size. The main differences are in features and programming; if you replace the battery and still have issues, you may need to re-pair the fob with the car or consult the manual or a dealer.
Summary
The 2014 Honda Civic key fob uses a CR2032 3-volt lithium coin cell. Replacing it is a straightforward process that most owners can perform at home with a coin and a fresh battery. Availability is high, and the cost is modest, making battery changes a routine part of vehicle maintenance.
