What battery does a 2014 Nissan Altima key fob take?

Will the Deluxe CR2032 fit my Altima key fob?
The Deluxe pack is listed as CR2032 3V, which matches the battery type Nissan specifies for the original key. Check your own fob and the fitment guide on the Amazon listing, especially if your key is an aftermarket replacement.
How many batteries does the fob need?
One. The Deluxe pack contains two cells, leaving one for a spare or another compatible device.
Which side of the battery faces the bottom of the case?
Nissan says the positive (+) side faces the bottom of the case. The generic steps on the Amazon listing say positive side up, which conflicts with Nissan’s wording for this key. Follow Nissan’s instruction.
Do I need to reprogram the key after changing the battery?
Nissan’s battery replacement procedure ends with testing the buttons and has no programming step. The Amazon listing also says no programming is required.
Can I use a CR2025 or CR2016 instead?
No. They share the 20mm diameter but are thinner (CR2025 is 2.5mm, CR2016 is 1.6mm) and have lower rated capacity in Panasonic’s lineup. Nissan specifies CR2032.
How long will the battery last in the fob?
No installed-life figure is published for this Deluxe product, and runtime depends on how often you use the fob. Nissan tells owners to replace the battery as soon as the low key battery warning appears.

No. The Amazon listing shows it as single-use, and conventional CR2032 cells are primary lithium cells that must not be recharged.
Is it a genuine Nissan battery?
Nissan endorsement has not been confirmed. The Amazon listing claims the cells come from the same manufacturer Nissan uses, and no supporting documentation was found. What is confirmed is the matching battery type: CR2032 3V.

Nissan’s backup method: shift to P, press the brake firmly, touch the ignition switch with the Intelligent Key until a chime sounds, then push the ignition switch within 10 seconds while holding the brake.
How should I dispose of a used CR2032?
Do not put it in household trash or recycling bins. Tape the terminals or bag each cell individually and take it to a battery collection or hazardous-waste service. Keep used cells away from children.
