2013–2019 Nissan Sentra Key Fob Battery Type and Replacement

Which Nissan Sentra model years does this cover?

These key fob battery specifications apply to every Nissan Sentra built from 2013 through 2019 — the B17 (7th generation), compact sedan. Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What changed during the 2013–2019 Nissan Sentra

• 2013Generation launch, 150 lb lighter than the B16, 1.8L MRA8DE with CVT or 6MT, FE+ aero-economy trims
• 2014Revised CVT calibration, steering, and suspension tuning for a smoother, more responsive drive; powertrain otherwise unchanged
• 2015Chassis retuned again for improved refinement, per Nissan; powertrain carries over unchanged from 2014

What battery does the 2013–2019 Nissan Sentra key fob take?

A single CR2025 (Intelligent Key) coin cell.

Can you use a CR2032 instead of a CR2025 in a 2013–2019 Nissan Sentra key fob?

Usually. Both are 20 mm across; the 2032 is 3.2 mm thick against the 2025's 2.5 mm, so it holds more charge but is a tighter fit and can strain the contacts in a shallow housing. If the case will not close cleanly, use the specified CR2025 (Intelligent Key).

How do you open a 2013–2019 Nissan Sentra key fob?

Slide out the mechanical emergency key first, which usually releases a catch, then part the halves with a plastic pry tool or a coin wrapped in tape. A screwdriver will mark the case and can crack the seam.
