I did see this one listed on eBay.
I thought about rolling the dice but that is getting pretty close to the same price as going straight to Nissan.
My fob/remote was a separate from my key. they weren't one unit like this one
I did try one of these https://www.ebay.com.au/itm/FACTORY-NISSAN-REMOTE-KEYLESS-ENTRY-OEM-TRANSMITTER-GREY-PANIC-FOB-KOBUTA3T/153103888051
It looked pretty much identical to my old one, only my old one had a twist type battery cover on the back side.
I put a fresh battery in this one and tried to program it, no dice.
I suspect it could be for left hand drive models only.
