How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2013-2016 Mazda CX-5 key fob takes a CR2032 coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2013-2016 Mazda CX-5 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 Mazda CX-5 model years does this cover? These key fob battery specifications apply to every Mazda CX-5 built from 2013 through 2016, the KE (1st generation), compact suv. Nothing in this specification changes between those model years. - [2013 CX-5](https://whichcarparts.com/cars/mazda/cx-5/2013) - [2014 CX-5](https://whichcarparts.com/cars/mazda/cx-5/2014) - [2015 CX-5](https://whichcarparts.com/cars/mazda/cx-5/2015) - [2016 CX-5](https://whichcarparts.com/cars/mazda/cx-5/2016) ## What changed during the 2013-2016 Mazda CX-5 | Years | What changed | | --- | --- | | 2013 | US launch; 2.0L only at first, 6-speed manual or automatic, FWD or AWD | | 2014 | 2.5L SkyActiv-G added on Touring/Grand Touring; 2.0L remains standard on Sport | | 2016 | Facelift (styling, chassis stiffening, updated i-Activsense safety suite); mechanical specs (oil, filters, wipers) carry over unchanged | ## 2013-2016 Mazda CX-5 key fob battery: common questions ### What battery does the 2013-2016 Mazda CX-5 key fob take? A single CR2032 coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2013-2016 Mazda CX-5 key fob? This fob takes a CR2032, 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 2013-2016 Mazda CX-5 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 - [Mazda global owner's manual, CX-5 KE lubricant quality and capacities](https://owners-manual.mazda.com/gen/en/cx-5/cx-5_8ft1ee17b/contents/10020102.html) - [NHTSA recall 16V-644, liftgate support struts](https://api.nhtsa.gov/recalls/recallsByVehicle?make=mazda&model=cx-5&modelYear=2014) - [NHTSA recall 16V-203, steering knuckle bolts](https://api.nhtsa.gov/recalls/recallsByVehicle?make=mazda&model=cx-5&modelYear=2015) - [NHTSA recall 16V-064, fuel filler pipe](https://api.nhtsa.gov/recalls/recallsByVehicle?make=mazda&model=cx-5&modelYear=2015) - [NHTSA recall 20V-063, LED daytime running lights](https://api.nhtsa.gov/recalls/recallsByVehicle?make=mazda&model=cx-5&modelYear=2016) - [Mazda Connect Infotainment Settlement, official settlement site (class definition, covered years)](https://www.mazdainfotainmentsettlement.com/) - [Mazda parts catalog, PE01-14-302 oil filter cartridge](https://parts.mazdausa.com/p/Mazda__CX-5/CARTRIDGE--OIL-FILTER/105508476/PE01-14-302.html) - [Wikipedia, Mazda CX-5 first generation engine/trim history](https://en.wikipedia.org/wiki/Mazda_CX-5) - [Edmunds, 2016 Mazda CX-5 review and specs](https://www.edmunds.com/mazda/cx-5/2016/review/) ## Other Mazda CX-5 generations - [2017-2025 Mazda CX-5 key fob battery](https://whichcarparts.com/cars/mazda/cx-5/2017-2025/key-fob-battery) Or [compare all generations](https://whichcarparts.com/cars/mazda/cx-5/key-fob-battery). ## More for the 2013-2016 Mazda CX-5 - [Oil & filter](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/oil) - [Battery](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/battery) - [Tires & wheels](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/tires) - [Wiper blades](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/filters) - [Bulbs](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/bulbs) - [Brakes](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/brakes) - [Fluids](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/fluids) - [Service schedule](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/common-problems) - [Oil light reset](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/oil-reset) - [Specs](https://whichcarparts.com/cars/mazda/cx-5/2013-2016/specs) Specifications vary with engine option, production date, and market.
