I've been getting the low battery warning on my fob for the last month?? so I finally decided to replace the batt before it got too low as to not work. I had both the correct cr2025 and the larger capacity cr2032. I figured I'd give the 2032 a shot since the original 2025 only lasted me 1.5 years, although going off when the car was made it made 27 months.
I did have a bit of a time getting the two halves to snap together, I ended up having to first snap one side closed and then I was able to just barley get the other side to completely close. I'm a bit worried about how they'll separate the next time I need to replace the battery as it did make a rather loud "click" when it finally closed. Time will tell and when the time comes I'll update this thread with how it went. All buttons seem to work just fine although truthfully I never use them, I always push the door handle button to lock and unlock the car and use the interior button to open the charge door, the fob just sits in my pocket untouched.

Here are some specs on the batteries.

note they differ by thickness and capacity.
After reading the posts, there appears to be some problem batteries...one would want to use a high quality fresh product for the installation. Perhaps even check that the voltage is 3 volts before using
I replaced the battery with a CR2032 in my fob and it has been working fine in my 2011 car for three years.

Model of the battery type are exact dimensions of the battery
CR2032 is 20mm diameter 3.2mm thick
Guess the other one

Tesla EV uses 18650 cells. 18mm diameter and 650mm length.
Leaf uses Harry Potter books. Measured in pages.

Or $1.00 apiece as my wife proved to me by getting one at a place I thought I would never go to -- Dollar Tree.

I love Dollar Tree!

I used Dollar Tree (Sunbeam brand) CR2032s in my wife's Volt fobs. They only lasted a year, but I did get two for my dollar. I rarely see CR2025s available in the Dollar Tree stores local to me (only one time).

I dropped by Advance Auto Parts and they had fresh EverReady 2025 in a two pack for $4 with a use by date of 2024. Thumb nail opened the fobs just fine and we replaced the original circa 2013 OEM Sony batteries in both fobs of my 2014 Leafs in a few moments and verified they worked before I left the store. I should be good for another 2 years at $1 per year per fob. Just remember to keep the fobs away from your cell phone or other WiFi/Bluetooth devices and fresh quality batteries should last for years.

I was also told by a Nissan Dealer parts department that a CR2032 would fit and work where a CR2025 was used. they stated it was only a few mm thicker... and are cheaper to get.. I stock maxell CR2032 that I pay $0.99 each.

It does fit but I'm not sure I'd advertise it as a good solution for everyone. I did it but it was extremely hard to get both halves to snap back together either on my 3 or 4 button remote, can't remember right now but I do remember one style just barely snapped together while the other took even more pressure. Yes it's only a fraction of a inch(.098" for a 2025 and .126" for a 2032) but the remote is built to pretty close tolerances. I only plan on using the 2032 but again I'm not sure I'd advertise it as a positive match

2032 is 20mm in diameter and 3.2mm in thickness. 2025 is 20mm in diameter and 2.5mm in thickness.
So the difference is 0,7mm. Metric system is that easy

Tesla uses 18650 cell, those are 18mm in diameter and 65.0mm in height. Gigafactory will make 21700, so 21mm and 70.0 mm.

Just saying. It is easier to know how things work rather than ask again with 2016 vs 2025 cells

I wouldn't push 2032 cell if it goes with huge force. Depends, haven't tried really.
2032 has significantly more capacity due to extra thickness. A third more.
