The 2017 Nissan key fob typically uses a CR2032 3V lithium coin battery.
That CR2032 is the standard for most Nissan Intelligent Key remotes from that era, though some models or production runs may vary. If you’re unsure, inspect the battery inside the fob or consult the owner's manual. Replacing the battery is a quick DIY task that usually restores full function within minutes.
Here are the typical steps to replace the battery in a 2017 Nissan key fob:
- Gather a small flat-head screwdriver or plastic pry tool, a fresh CR2032 battery, and a clean workspace.
- Remove the mechanical key from the fob to prevent damage while opening the case.
- Carefully pry apart the two halves of the fob along the seam, using gentle leverage to avoid damaging the circuit board.
- Remove the old battery and note its orientation (which side is facing up).
- Insert the new CR2032 with the positive side facing up toward the battery contact, ensuring it sits flat and makes good contact.
- Snap the fob halves back together and reinsert the mechanical key; test the remote by pressing lock/unlock to confirm it works.
After replacement, test the fob from various distances to confirm reliable operation. If it still doesn’t work, the issue may be with the vehicle’s receiver or the fob may require reprogramming; contact a Nissan dealer or automotive locksmith for assistance.
Battery type and compatibility
For most 2017 Nissan key fobs, the correct battery is CR2032 3V. Some fobs from this era could use CR2025 or, less commonly, CR2016 depending on specific model or batch. To be sure, verify by inspecting the old battery or consulting the vehicle’s manual or a Nissan service resource.
Quick verification tips
Open the fob and read the size printed on the battery, or compare the new battery to the old one to confirm the match. CR2032 batteries are 20 mm in diameter and about 3.2 mm thick; CR2025 batteries are also 20 mm in diameter but about 2.5 mm thick.

Replacing it is a straightforward at-home task, and verifying the correct size before purchase helps ensure a smooth swap.
