The CR2025 is 2.5 mm thick, the CR2032 is 3.2mm thick, so 0.7mm thicker and a correspondingly slightly greater capacity. They are both 20mm in diameter, hence the nomenclature. As Matt indicated the voltage is the same but increased capacity would allow it to last a bit longer. I'm getting about 3 years with the 2025 on the lesser used fob. Thanks for a useful video Matt!
Thanks Matt. This was super helpful. I didn’t want to risk busting my key fob by forcing it open at the wrong point - now I know how to open it safely and which replacement to use! 😃
Had the same experience you described at the intro. I knew I needed to get a new battery, but wasn't sure which. Really appreciate the tutorial and battery recommendations. Thanks!
Thanks for doing this video. I couldn't figure out how to pry the case open. Also nice to know that the 2032 battery will work; that's what my Acura uses.
I'm glad I found this. I put in a new CR2025 and it didn't work. I checked the battery with a voltmeter and it was good. Thought maybe I didn't put it back together correctly. Watched this video and put a CR2032 in the fob and it's working great.
Watched a couple of vids that didn't really help because different Nissan key fobs are just that, different. Then found yours for the Leaf & changed the battery after watching 1st time. Thanks!
If your concern is getting grime on the battery, gratefully the battery prongs scrape the battery surface when installed, making for a good mating surface.
Thanks for a useful video. Just to say that I have found the same as some others on a 2019 Leaf. One key fob seemed to be happy with a CR2032 but the other wasn't and whilst it would open the car, it wouldn't close it, so perhaps the slightly thicker battery is a problem. Still useful to know how to open the fob without damage though.
I noticed that the keyfob range had decreased. Had to be within a metre or two for it to work. So I thought the battery must be getting low. Swapped the battery to a new CR2032 as per this video. Now the fob works perfectly and the keyfob range is back to normal. Just wanted to mention that it would be good to change the battery when you notice the keyfob's range has reduced so you avoid getting the "Can't start car" scenario.
Actually, I chickened out. Even though the CR2032 worked perfectly, after reading the comments, I swapped it out for a CR2025. As the car is driven by other family members I don't want to risk any issues. If it was only me driving it I would have stuck with the CR2032. If it ever stopped working I would know to use the "use the keyfob to press the start button" trick.
Thanks for this helpful video. We had a CR2032 in the drawer so that's what I put in. We'll see if it works okay. I have read about a few people having problems. But if I am not one of those people, then great!
I didn't find a 2032 cell worked for my 40kWh 2020 leaf in the uk. 2025 works fine. It seems to fit but the key refused to work. Nissan dealer says this is a common problem when people change them with a 2032 cell.
Thanks so much did the trick. Why on earth couldn't they just have doubled up on the trap door switch they made for the manual key which works well and had one for the battery. The FOB for my 2015 Leaf is starting to get beat to death from this janky process that weakens the plastic catches over time.
A false economy(?) The price difference is negligible, most of these batteries come in 2s or 4 to a pack. If normal life is 3+ years, half the pack will go to waste if you store them too long. All you achieve is flexing the PCB an extra 0.7mm which doesn't sound much but it's enough when you factor in the other strains of pocketing the fob. The tiny spring contacts need to flex to maintain good battery contact, maybe fine first or even second time will be OK but as the plastic dries out it becomes more brittle and thus more likely to fail. If the coil mount fails and deforms you lose the emergency option to power the fob directly from proximity to the on button if the battery dies while you are driving. Also, clean your hands before handling coin batteries or better, use plastic tweezers they are slow low discharge and the acid from skin is enough to start corrosion - you need to be super clean with fobs, watches etc to ensure good long term connections. It's just not worth the eventual consequences
All good thoughts, and I’d add on: - if the battery in the fob is dead, you can still do the emergency start of the car. Essentially the RF ID tag in the key fob is energized when put in close proximity to the ignition button, so it’s OK if your battery is completely dead. Same way NFID tech works to do touchless transaction with your credit card. - it’s always good to wear gloves and keep everything clean, but I would humbly submit, any grime that could potentially build up on the battery will be scraped away when the contacts are put into place, touching the battery. Or at least I’d suggest, you’re splitting hairs, and it would be super hard to find power failure as a result of not wearing gloves. And absolutely you can use the 2032 battery at spec. For what it’s worth, we’ve been using the larger size batteries for years now on both of our Nissans, and gratefully the key fobs are working exactly as designed.
I did this. The red flash red when I press the buttons. But it doesn't seem to communicate with my vehicle. Anything else I need to do? Maybe some kinda special code or button combination? I don't have a great relationship with the dealer and I dont want to go to them if I don't need them 🙍🏽♂️
Annoyingly there isn't a way to program a keyless fob and pair with a vehicle (at least in what I've found, which is all for keyed ignitions). I would ultimately recommend taking it to the dealer, *but* be expressly clear that you swapped the battery in the fob and it depaired, in the chance they can just reprogram it for free. Indeed nothing worse than these types of built-in service requirements that make dealers more money with no DIY option.
Nice. Just bought a 2020 leaf and its giving me a low battery alarm on the key. I was concerned about re pairing the key with the car but it seems to not be too much of a problem.
The 2032 fit into mine just fine, but it did not work, nor did another one. The 2025 worked fine. Maybe it's coincidence and the 2032s I had were bad. I tested 'em with a 100-ohm load and voltage dropped to < 1v. With a 237-ohm load though, one of them stayed well above 2v. Dunno what load the key fob puts on the battery, but I imagine it's not much more than 10ma.
Hm this may sound weird, and perhaps its just me, but I kept running into issues with the seemingly simple replacement process... I found the key fob (especially around the battery) to be really fickle for some reason, at least for me...if things arent working for you still, try taking it completely apart and cleaning things with a soft brush and microfiber cloth to remove any dirt or debris found around the edges. Then, try installing the battery chip side first (and make sure its the correct side (- negative) is making contact with things... afterwards, continue to loosely put it together with all the correct and corresponding pieces in its correct place as there arent too many parts to mess things up...at least there shouldn't be. After loosely seating the battery via the negative side first, make contact with the positive terminal piece and begin pressing a few buttons to see if the doors and locks react; it should be...but You might have to play with the battery a.As I alluded to earlier, I was baffled as to why things would work until I would put it all together.I found out that its possible to seat the chip part (negative side) too snug, which would somehow stop things from working as it did just moment earlier...it didnt stay working until I loosely placed all the pieces together. Other than the battery and the two main outer plastic pieces, try not to press on anything else as it should loosely, but securely, come together fine on its own. Hope that sorta makes sense sense for any one of you running into similar problems? Good luck...
Try not to push any of the pieces together since I found out that the battery part can come together too snug in a manner that would prevent the key fob from working as intended... Put the pieces together as loosely as possible as only the outer hard plastic pieces should really be the only thing requiring some amount of pressure to secure. But u can test things even before having to put it all together and if it locks/unlocks stuff then it should continue to do so once everything is done. If not, try again and play around with the seating of battery and chip placement
I tested the battery that i replaced and the tester says it is good. I tested the new battery and it shows that it has a little more volts, and shows as good. But yeah, the new battery works and the old battery does not. So my point is that just a little voltage drop kills the fob.
I tried to replace the batteries in my 2 fobs and neither worked. I tried several batteries. Then went to dealer and they had a checker that showed that the fobs were not putting out a signal. They replaced the batteries and both fobs worked fine. I have no idea why but thats what happened.
The CR2025 is 2.5 mm thick, the CR2032 is 3.2mm thick, so 0.7mm thicker and a correspondingly slightly greater capacity. They are both 20mm in diameter, hence the nomenclature. As Matt indicated the voltage is the same but increased capacity would allow it to last a bit longer. I'm getting about 3 years with the 2025 on the lesser used fob. Thanks for a useful video Matt!
you bet! Indeed, a bit more mass means a bit more charge.
The 2032 doesn't seem to work on all Leaf fobs, not on my 2019 40Kw anyway. Good video nonetheless. Thanks
CR2032 worked perfectly in my 2012 Leaf.
Cr2032
Just an FYI, if you hold the fob near the Start button when you push it the car will start even with a dead battery because it also has an RFID chip.
Exactly right! Added as demo to my similar Nissan Rogue video th-cam.com/video/ioyzSDhFeKA/w-d-xo.html
thankyou life saver!
Super helpful. The 2032 is so much more common than the 2025. Had some at home already. Took me 2 minutes. Thanks for this!
You’re welcome!
Thank you. I happened to have a 2032 on hand, swapped out the batteries in seconds and I'm good to go. Great video!
Glad it helped!

Thanks! I just replaced my battery for my 2020 Leaf with a 2032 battery! The instructions in your video were perfect!
THANKS SO MUCH! I couldn't get my LEAF started at all, even though I put the key in the lock. Really helpful, thanks, again!

Very helpful. Just changed the battery in my wife's Altima fob. Saved me a bunch of time and frustration.
Very happy to see someone confirming what I have seen elsewhere, that CR 2025 battery will work, but the CR 2032 allegedly lasts longer.
Just get one of them in there!
Watched a couple of vids that didn't really help because different Nissan key fobs are just that, different. Then found yours for the Leaf & changed the battery after watching 1st time. Thanks!

Thank you, awesome video, just received a spare key with dead battery, have a pack of 2032 works perfectly.
Glad it helped!
Fantastic ! Brilliant clear BUT wearing gloves assures full success.

Did you have to reprogram
@@dejahmurry50 If you're using the same clicker - nope
Thanks man, you're a life saver. Was thinking I'd have to take it in for servicing.
Glad it helped!
Worked like a charm for my 2013 Juke. I have a bunch of 2032s in the house; they seem to be the universal button battery nowadays.
Glad to hear it!
Awesome thx. Was struggling with this on a 2021 model but works like a dream.
Top tip on the larger battery too ;-)

@@priscillagoseyun6352 you bet!
Sweet it worked and I had the bigger battery!
Glad it worked!
Also if you run out of batteries you can press in the start button with the end of the fob and it will turn on even with a dead battery
