I have a bit of a problem trying to replace a lost key fob. I lost my 2015 Nissan Rogue Intelligent Key (aka IntelliKey), type B (4 button). These are for keyless ignition vehicles, so there's no way to program new fobs at home, you have to go to the dealership (believe me, I've looked).
I didn't want to pay for the over-priced OEM fobs sold at the dealer ($200+) so I found a used one on ebay, and made sure it was the same type and style. The reason I wanted to buy used was that the dealer initially told me that there were a lot of fake non-OEM fobs out there that couldn't be programmed which is why I had to buy one from them. I decided that I'd just buy a used OEM fob on ebay instead, and the fob I received was in excellent shape and came with a pre-cut key, so it looks like it was indeed a used key.
I took it to the dealer for reprogramming, and was advised by the tech that once an Intelligent Key from 2013+ was linked to a car, it could never be reprogrammed to another car. I asked if we could at least try it, and he said that we could, but he guaranteed it wouldn't work and that I'd still have to spend $140 just to find out. He insisted he was just trying to save me money. If this is true, of course I wish I'd known before buying a used key, but I have not seen this claim repeated anywhere else online, and there are a ton of used fobs for sale claiming they can be reprogrammed.
Was this guy bs'ing me, or is this really the case? He said that it was only for fobs 2013 and later, and that he had a box of useless fobs. The thing is, the manual says that if you add new OEM keys to your car (up to 4) you have to bring all keys in for reprogramming because they each have to be erased. I know this isn't exactly the same as linking to a new car, but it implies that they can be completely erased and reprogrammed. I've attached a photo of the type of key I have and the manual excerpt. Thank you!
