2013–2018 Nissan Altima Key Fob Battery Type and Replacement

Which Nissan Altima model years does this cover?

These key fob battery specifications apply to every Nissan Altima built from 2013 through 2018 — the L33 (5th generation), mid-size 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 2013–2018 Nissan Altima

• 2013Generation launch: new platform, 0W-20 oil and NS-3 CVT fluid for the 2.5, 27/38 mpg
• 2016Mid-cycle refresh begins: new exterior styling and fascias, updated features; SR sport trim introduced (2.5 and 3.5)
• 2016–2018Major facelift: new fascias and hood, SR sport trim added (2.5 and 3.5), available Predictive Forward Collision Warning and Emergency Braking. Mechanical service specs (oil, filters, wipers, battery) carry over.
• 2017Carries over unchanged from 2016; a mid-year trim-lineup shuffle follows partway through the model year
• 2018Final year for the L33 and for the 3.5L V6 Altima

What battery does the 2013–2018 Nissan Altima key fob take?

A single CR2032 (Intelligent Key) coin cell.

Can you use a CR2032 instead of a CR2025 in a 2013–2018 Nissan Altima key fob?

This fob takes a CR2032 (Intelligent Key), so start there. The two cells share a 20 mm diameter but differ in thickness, and the thicker one does not always seat in a housing built for the thinner.

How do you open a 2013–2018 Nissan Altima 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.
