The battery size for a 2014 Honda key fob is typically a CR2032 3-volt lithium coin cell.
What battery size do 2014 Honda key fobs use?
For most 2014 Honda key fobs, the replacement part is a CR2032 battery. This is the standard size used in many Honda remotes from that era, including popular models such as the Civic, Accord, and CR-V. However, there can be exceptions based on the exact trim or key design, so it’s wise to confirm by inspecting your fob or consulting the owner’s manual or a dealer.
Before you replace the battery, it’s helpful to know that alternative coin sizes occasionally appear in certain fobs. The most common alternatives you might encounter are CR2025 and CR1616, though CR2032 remains the norm for the majority of 2014 Honda keys.
- CR2032 — the most common size for 2014 Honda key fobs; 3V lithium coin cell; diameter about 20 mm, thickness about 3.2 mm.
- CR2025 — sometimes used in marginally different fob designs; 3V lithium coin cell; thinner than the CR2032.
- CR1616 — found in older or smaller remotes; 3V lithium coin cell; smaller diameter and thinner than the CR2032.
In practice, the vast majority of 2014 Honda key fobs will require a CR2032 battery. If you aren’t sure which size your fob needs, check the code printed on the existing battery (if accessible) or consult the owner’s manual or a Honda dealer for confirmation.
How to replace the battery in a 2014 Honda key fob
Replacing the battery is a straightforward DIY task in many cases. The steps below provide a typical method, but always refer to your specific fob’s design and your owner’s manual if available.
- Remove the mechanical key blade (if your fob has one) by pressing the release tab and pulling the key out.
- Separate the two halves of the fob by prying along the seam with a small flat tool or a coin, taking care not to damage the plastic.
- Note the orientation of the old battery (which side is facing up) before removing it.
- Install the new battery with the correct polarity, typically with the plus (+) side facing up unless the fob indicates otherwise.
- Reassemble the fob, snap the halves back together, and reinsert the mechanical key if you removed it.
- Test the fob by pressing a button to ensure the car responds (lock/unlock, panic, or trunk release as applicable).
Tips for a smooth replacement: work on a clean, flat surface; avoid touching the battery contacts with your fingers to prevent oils from interfering with the connection; and store spare batteries in a cool, dry place.
Common issues and quick fixes
- If the fob still doesn’t respond after replacement, check the battery orientation and reseat it carefully.
- If you notice sluggish response or dead buttons, you may need to reprogram the fob at a dealer or with a professional locksmith.
- Keep a spare CR2032 on hand, as these batteries are inexpensive and widely available at electronics stores and supermarkets.
In summary, for most 2014 Honda key fobs, the recommended replacement battery is a CR2032 3V lithium coin cell. When in doubt, verify by inspecting the existing battery or consulting the owner’s manual or a Honda dealer, and follow safe replacement practices to ensure proper fob function.
Summary
Most 2014 Honda key fobs use a CR2032 battery. If your fob design is unusual, you may encounter CR2025 or CR1616, but CR2032 remains the default.
