A quick answer: most Nissan remote key fobs use a CR2032 coin-cell battery, though some older or smaller remotes may use CR2025 or CR2016. The exact size depends on your model and generation.
Beyond that, battery size can vary by year and region. To be certain, check your owner's manual, inspect the fob’s battery, or consult Nissan’s support resources for your specific model.
Common battery sizes you may encounter
The following coin-cell sizes are the ones you’re most likely to encounter when replacing a Nissan fob battery.
- CR2032 — The most common size for newer Nissan remotes and Intelligent Keys.
- CR2025 — Used by some older or smaller fob designs.
- CR2016 — Less common, typically found in very compact fobs.
Bottom line: start with CR2032 for most recent models, but verify against your specific fob to avoid buying the wrong size.
How to confirm the correct battery size for your specific fob
To be certain, follow these steps and avoid guessing at the store.
- Check the owner's manual or Nissan's official support pages for your exact model and year to see the recommended battery type.
- Open the key fob casing carefully to expose the battery, noting how the old battery is seated and its markings.
- Look for a size or voltage marking on the battery itself (for example, “CR2032”).
- If the old battery is not legible, compare the old battery’s diameter and thickness with standard coin-cell sizes (CR2032 is 20mm in diameter, 3.2mm thick).
- If you’re unsure, bring the old battery or the fob to a Nissan dealer or reputable parts retailer to confirm the correct size before purchasing.
- Install the new battery with the correct orientation (+ side up, or as indicated inside the fob) and reassemble the case securely.
- Test all fob functions (lock, unlock, trunk release, and any other features) to ensure proper operation.
If you’re still unsure after these steps, contact a Nissan dealership or use Nissan’s official parts lookup for your VIN to confirm the exact battery size for your vehicle.
Replacement tips and safety
Keep these tips in mind to ensure a smooth replacement and reliable fob performance.
- Use a non-metallic pry tool or a plastic card to avoid damaging the fob’s housing or circuitry.
- Work on a clean, dry surface and avoid touching the circuit board inside the fob.
- Handle new batteries with clean hands and avoid touching the battery’s metal terminals to prevent oils from your skin transferring.
- Dispose of old batteries properly at a receptacle that accepts spent lithium coin cells.
- After reassembly, if the fob still has trouble, the issue may be button contacts or the need for reprogramming rather than the battery itself.
With the correct battery installed and the fob properly reassembled, you should see a reliable range and responsiveness from your Nissan remote.
Summary
In most cases, your Nissan remote key fob takes a CR2032 battery, but CR2025 or CR2016 may appear in older or smaller models. Confirm the exact size by checking the manual, inspecting the current battery, or consulting a Nissan parts pro. Replace with the correct size, install correctly, and test all functions to ensure proper operation.
