So I decided to buy an OEM fob from someone on eBay...(I know...) Went to have the local Nissan dealership program it. They said he was unable to make it work but in the process also made it so my current fob that has worked just fine, stop functioning as well. So now I've lost all button function, keyless entry, everything. Very annoying. They explained the programming process to me and said that that happens sometimes. They also said that my BCM may be bad or the antennas may be bad. Has anyone ever had to deal with this? Everything was fine before I took it to them. I guess I just don't understand how an issue with the BCM can suddenly just pop up at that moment.
I went through a key issue recently so Ill tell you what I found during that whole process and with help from VStar650CL
Buying keys off ebay is not a good idea for 2 reasons:
1) you have to match the key model or radio frequency or whatever to your specific car. If you don't get the right one, it will never work.
2) for some reason if a key is programmed to another vehicle already it doesnt seem to ever accept new programming to your car. This may be a security feature or something but basically it makes them useless if it is not a brand new key that has never been programmed.
That 2nd part *might* not be fully true, but I found that info in multiple places when searching around while I had my key problem. So you should really just bite the bullet and pay the exorbitant cost Infiniti charges for a new key rather than take the risk on it.
Next up, when the key programming process starts, it erases all stored keys. You must have all keys with you to be programmed because any original key will be deleted from the cars memory and have to be re-added. This works even though the original key was already programmed because the key's memory is already matched to your car's data or whatever.
So what happened to make your old key stop working was they started the process, the new key failed, but because the process was started the old key was removed from the car memory. When the dealer gave up on your car, they *should have* done the process just one more time with only using your original key to get its functionality restored even if they couldnt do the new key.
As VStar said, the Consult 3 sometimes has issues with our cars being made for a Consult 2. The dealer that did my reprogramming had to bring a Consult 2 out to do it, they spent an hour with a Consult 3 and never got it to work.
Lastly, since your key works while being in the key port, they did actually do some of the programming. Otherwise your car wouldnt start at all. It is a multi-step process that first must register the key, which they did, and then they must register the remote functions. So because they failed to program the remote functions, that is why your key can no longer do the door unlock/lock and why it doesnt register with the antenna in the car for the pushbutton. It is this remote programming stuff that seems to have to be done on a Consult 2. A C3 and aftermarket software is all able to do the security program 1st step part, but not move on to the 2nd step.
I would recommend a dealer for this, and I know you just had a bad experience at one. But from my own experience trying to go the cheap route with a mobile locksmith, they just dont have the software and know how to do the 2nd step with the remote programming, only the 1st step security programming. So my advice is try to find a dealer with a Consult 2 and ask if they have done key fob reprogramming on older Infiniti's before.
