I tried to take mine apart just out of curiosity and had the same experience. I got nowhere using screwdrivers or fingernails. I was able to open it with a knife blade. I was a bit surprised to see that the battery is installed "upside down", i.e. with the + and battery type information not visible. I would think some people might be tripped up by that, but since you were able to use the fob afterward to open the doors you obviously didn't fall into that trap.

(And I tested the new battery with my voltmeter and got 3.2 volts vs 2.9 in the weak battery). Car would not turn on. Door unlock would function.
So you have two fobs that work to open the doors, but not to power up the car (except by touching the power button). I don't think this has anything to do with replacing the batteries. It sounds like something wrong with the radio transceiver used inside the car (which is separate from the ones used to communicate with the fobs outside the car). By the way, 2.9v doesn't strike me as terribly weak. Mine is at 3.03v after only five months of use.

As well you should be if that were true. But it isn't, as many others can attest. Needing a service call for a failing transceiver, though, would be expected. Please tell us what the final resolution of this is.

And by then it will have just enough battery capacity to unlock the doors before it goes dead! :lol:

Will the LEAF start if the Key Fob Battery is DEAD?

My friend has a Honda and he told me that if the battery is dead in the key fob that he can start the car by pressing the start button with the key fob. That the direct contact of the fob to the start button makes the connection! Pretty crazy!

That's 2.5 years on this fob battery. I've switched to the second fob for a while and have put the replacement on my to-do list.

Yes, the LEAF works the same way. I understand it is a very short range RFID chip which allows that, so in theory you wouldn't even have to press or touch the button with the fob, but just have it very close. Clearly, though, pushing the button with the fob is the most reliable way to accomplish that.

I believe "2025" and "2032" are supposed to be indicating the battery's dimensions, i.e. "20" --> 20 mm in diameter whereas "25" and "32" --> a thickness of 2.5 mm and 3.2 mm respectively.

Yes, I confirmed that it works when I tried using a 2032 battery and although it would open the door, nothing else would work.
The LEAF can read the RFID built into the fob when it is in extremely close proximity to the start button even if the fob battery is missing.
And you can always get into to LEAF using the manual key built into the fob (unless the manual key opening or its mechanism is frozen up in icing conditions).
