The standard battery used in most 2020 Nissan key fobs is a CR2032 lithium coin cell, though some thinner or specific regional variants may use a CR2025. Check your particular fob or the owner's manual to confirm the exact size.
Battery sizes commonly used in 2020 Nissan key fobs
The two coin-cell sizes you’re most likely to encounter are CR2032 and CR2025. Identifying the correct one ensures you buy the right replacement and avoid fit issues.
- CR2032: A 20 mm diameter, 3.2 mm thick coin cell. This is the most common size for 2020 Nissan fobs and fits the majority of models without issue.
- CR2025: A 20 mm diameter, 2.5 mm thick coin cell. Some thinner or regional fobs may use this size. If you’re unsure, verify the exact battery type before purchasing to ensure proper fit.
In practice, most owners will need CR2032 for their 2020 Nissan key fob. CR2025 is less common and typically appears only in specific, thinner remote designs.
How to replace the battery in a 2020 Nissan key fob
Replacing the battery is a straightforward DIY task. The steps below describe the typical process for most Nissan fobs, but if your model differs, consult the manual or dealer support.
- Locate the seam or release mechanism on the fob’s back cover. If your fob has a hidden mechanical key, remove it first to access the case.
- Carefully pry open the back cover using a small flat tool or a coin. Work slowly to avoid damaging the plastic.
- Take note of the battery orientation (which side is facing up) before removing the old cell.
- Replace with a new battery of the correct size (CR2032 is the typical choice for most 2020 fobs). Ensure the positive (+) side faces the correct direction as indicated inside the compartment.
- Snap the back cover back into place and reinsert the mechanical key if you removed it.
After replacing the battery, test the fob by locking/unlocking the doors or pressing the panic button to confirm it’s working. If the fob does not respond, the battery may be dead or the fob may require re-synchronization with the vehicle, which is outlined in the owner’s manual or by your dealer.
Tips for identifying and avoiding issues
To minimize future problems, keep spare CR2032 batteries on hand and store the fob in a cool, dry place. If you’re unsure about the battery size, bringing the fob to a Nissan dealership or an automotive parts store for confirmation can prevent ordering the wrong size.
Where to buy and why accuracy matters
Coin-cell batteries are widely available at auto parts stores, electronics retailers, and online. Aim for name-brand or reputable third-party batteries to ensure reliability and prevent leakage. Using the wrong size or incorrect orientation can prevent the fob from working, so double-check the size and fit before finalizing your purchase.
Summary
For a 2020 Nissan key fob, the typical battery size is CR2032, with CR2025 appearing in some thinner or regional variants. Replacement is a simple, at-home task: open the back, swap in a new coin cell with the correct orientation, and reassemble. If the fob doesn’t work after replacement, verify the battery size again and consult the manual or dealer for re-synchronization guidance.
