In most 2014 Nissan key fobs, the battery required is a CR2032 3-volt coin cell. This compact, widely used battery powers the remote's locking, trunk, and panic functions.
While CR2032 is the standard for the majority of 2014 Nissan remotes, a small number of trims or export variants might use a different coin cell size. To be sure, check the inside back cover of your fob for the battery type, or refer to your owner's manual. The steps below outline how to confirm and replace the battery safely.
Identifying the correct battery
Use these quick checks to verify the proper coin-cell size for your fob before buying a replacement.
- Most 2014 Nissan key fobs use a CR2032 3V coin cell.
- Some rare or very early designs may use a CR2025; if you see a thinner battery or a different marking, verify before purchasing.
- When in doubt, remove the existing battery and read its markings to confirm the exact size before shopping for a replacement.
Confirming the size helps ensure you have the right replacement and avoid returns or delays at the store.
Step-by-step replacement guide
If you plan to replace the battery yourself, follow these steps to minimize damage to the fob and ensure a proper seal after reassembly.
- Purchase a fresh CR2032 3V coin-cell battery from a reputable retailer.
- Turn the fob over and locate the seam where the two halves meet.
- Use a small flathead screwdriver or a dedicated fob opening tool to gently pry apart the two halves at the seam.
- Carefully remove the old battery, noting the orientation (which side faced up).
- Inspect the battery contacts for corrosion or dirt; if present, wipe gently with a dry cloth.
- Place the new CR2032 into the cavity with the positive (+) side facing up, aligning it with the contacts.
- Press the two halves back together until they snap securely.
- Test the remote from a short distance to ensure all buttons work (lock, unlock, trunk, panic).
- Dispose of the old battery responsibly at a battery recycling point.
Ensure the fob is fully reassembled and the rubber seals are seated correctly to maintain water resistance.
Model-specific notes
Smart keys vs standard fobs
Across 2014 Nissan models, the majority of key fobs use the same CR2032 coin-cell battery inside the remote housing. Some higher-trim or smart-key systems may include a smart-key fob that also relies on a CR2032 battery inside the card-like device; the replacement process is the same as for standard fobs, though some models may require the physical key blade to be removed first.
If your key fob has a built-in emergency key blade, you can pull it out to reveal the seam and battery compartment more easily. Always handle the fob gently to avoid damaging the internal electronics.
Summary
The standard battery for most 2014 Nissan key fobs is a CR2032 3V coin cell. Confirm the size by inspecting the fob or checking the owner’s manual, then replace it with a fresh CR2032, following careful steps to open the fob, swap the battery, reassemble, and test. Proper disposal of the old battery is important for safety and the environment.
Bottom line: If you own a 2014 Nissan key fob and it stops responding, a fresh CR2032 battery is usually the right fix, and replacement is a straightforward DIY task for most owners.
