The 2014 Honda CR-V key fob typically uses a 3-volt lithium coin cell, most commonly a CR2032. Some remotes or regional trims may use CR2025 or CR2016, so verify the exact size by inspecting the current battery or consulting the owner's manual.
Battery options by fob type
Different CR-V key fobs from that era come in a couple of formats. The most common sizes are CR2032, with CR2025 or CR2016 appearing in certain variants. Here’s how the options break down for the 2014 model year.
Standard remote key fob
The standard remote key fob used with many 2014 CR-Vs typically requires a CR2032 battery. In some versions, a CR2025 battery may be used due to a thinner fob design.
- CR2032 — 3V lithium coin cell, widely used and readily available.
- CR2025 — 3V lithium coin cell, thinner profile (less common for this year but possible in some trims).
- CR2016 — 3V lithium coin cell, rarely used but present in certain markets or older variations.
To be sure, open your fob and check the battery size printed on the old battery or refer to the owner's manual for your trim’s specification.
Smart key fob
Some 2014 CR-V trims offered a smart key variant. These fobs generally use a 3V coin cell as well, most commonly CR2032, though an alternative size can appear in regional versions.
- CR2032 — the standard choice for many smart keys.
- CR2025/CR2016 — less common but possible depending on the exact design of the smart key.
If you’re unsure, verify by inspecting the existing battery or consult the vehicle’s manual for your specific trim and market.
Replacing the key fob battery
Replacing the CR-V key fob battery is a straightforward, plug-and-play process. The steps are similar across most 2014 models, but always handle the fob gently to avoid damage to the internal electronics.
- Identify the seam or opening point on the fob. Use a small flat tool or coin to pry apart the two halves gently.
- Remove the old battery, noting its orientation (which side faced up).
- Insert a new battery of the same size, ensuring the correct polarity (positive side typically faces up).
- Reconnect the halves and press firmly to snap the case closed.
- Test the fob by pressing buttons to confirm they work before reinstalling any covers or decorations.
- Recycle or dispose of the old battery at a proper battery recycling facility per local regulations.
After replacement, if the remote still doesn’t respond, check the battery orientation again, inspect for corrosion, or contact a dealer or automotive locksmith for assessment.
Tips and troubleshooting
Helpful reminders to keep your key fob functioning reliably:
- Avoid touching the battery contacts with fingers—grip the edges to prevent oils from affecting contact.
- Do not mix battery types or brands in the same fob if you have multiple remotes.
- Keep spare batteries of the correct size in a cool, dry place so you’re ready when replacement is needed.
Following these tips can extend the life of your key fob and reduce the chance of malfunction after a battery replacement.
Summary
In short, the typical 2014 Honda CR-V key fob uses a 3V lithium coin cell, most often a CR2032. Some models may use CR2025 or CR2016 depending on trim or region. To replace it, open the fob, install a new battery with the correct polarity, reassemble, and test. When in doubt, verify the size by inspecting the old battery or consulting the owner’s manual and recycle the old battery responsibly.
