How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2013-2019 Nissan Sentra key fob takes a CR2025 (Intelligent Key) coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2013-2019 Nissan Sentra key fob battery - Pry the fob open gently at the seam with a small flathead screwdriver or a coin, working around the edge. Many fobs have a hidden release slot near the key ring or emergency-key blade. - Note the battery orientation (usually positive side up) before removing the old cell. - Avoid touching the new battery's faces with bare fingers; skin oils can shorten its life. - If the fob doesn't work after replacement, check that the battery is seated fully and the contacts weren't bent. Most vehicles do not need re-pairing after a battery change. ## 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. - [2013 Sentra](https://whichcarparts.com/cars/nissan/sentra/2013) - [2014 Sentra](https://whichcarparts.com/cars/nissan/sentra/2014) - [2015 Sentra](https://whichcarparts.com/cars/nissan/sentra/2015) - [2016 Sentra](https://whichcarparts.com/cars/nissan/sentra/2016) - [2017 Sentra](https://whichcarparts.com/cars/nissan/sentra/2017) - [2018 Sentra](https://whichcarparts.com/cars/nissan/sentra/2018) - [2019 Sentra](https://whichcarparts.com/cars/nissan/sentra/2019) ## What changed during the 2013-2019 Nissan Sentra | Years | What changed | | --- | --- | | 2013 | Generation launch, 150 lb lighter than the B16, 1.8L MRA8DE with CVT or 6MT, FE+ aero-economy trims | | 2014 | Revised CVT calibration, steering, and suspension tuning for a smoother, more responsive drive; powertrain otherwise unchanged | | 2015 | Chassis retuned again for improved refinement, per Nissan; powertrain carries over unchanged from 2014 | | 2016 | Facelift: new front/rear fascias and lights, available LED low beams (SL), updated steering/suspension tune, added driver-assist options | | 2017 | SR Turbo (188-hp 1.6L MR16DDT) and NISMO join the lineup; 1.8L re-rated to 124 hp (CVT) | | 2018 | Automatic Emergency Braking made standard | | 2019 | Final B17 year; SR Turbo and NISMO's last year, the last factory-hot Sentra to date | ## 2013-2019 Nissan Sentra key fob battery: common questions ### 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. ## Sources - [2017 Nissan Sentra Owner's Manual (oil, capacities, NS-3, tires, bulbs, CR2025)](https://owners.nissanusa.com/content/techpub/ManualsAndGuides/Sentra/2017/2017-Sentra-owner-manual.pdf) - [2013 Sentra Factory Service Manual, Engine Lubrication (4.0 L with filter)](https://www.nicoclub.com/service-manual?fsm_download=Sentra/2013/LU.pdf) - [BBB National Programs, Nissan CVT Stringer class action (2013-2017 Sentra, 84 mo/84k)](https://bbbprograms.org/programs/dr/class-action/nissan-cvt) - [Martinez v.
