Fob and key in fob question

Asked by Mar 21, 2017 at 09:02 PM about the 2008 INFINITI QX56 Base

Question type: Maintenance & Repair

Fob wasn't working, changed battery and
still wasn't working. Took key out of fob
and it didn't work in ignition. Weird. We
have another fob and it works fine and its
key works fine in the ignition. Took key
from fob that is working and put it in the
fob that wasn't working and the fob works!
Then put the non working key back in that
fob and the fob still works, but when I tried
the non working key in the ignition again it
wouldn't start the car.

Update it has been a few hours and now
the non working fob is not working again!!

ollow these instructions in the order they are listed: Close and lock all doors to your INFINITI vehicle. Insert and remove the key you wish to program from the ignition key cylinder six times within ten seconds. You’ll want to do it swiftly but without damaging your system, so remove it completely each time and be firm but not rough. When done correctly, the warming lamps and interior lights will flash twice. Insert the key you wish to program into the ignition key cylinder and turn it to the Accessory Position. At this point in the process, all of the original ID codes are erased. So you will have to reprogram all of your remotes at this time. With your key in the Accessory position of the ignition key cylinder, press any remote on the new controller ONE time. The warning lamps and interior lights will flash twice when this step is completed accurately. To program an additional remote, press the unlock button on your new key fob, then press the lock button on your door. Continue this process with each additional key fob (up to four total). The warning lamps and interior lights will flash twice after each remote programming when done correctly. Once finished, remove the original key from the ignition. Unlock the driver side door, open the door and then close the door. The remotes should all be programmed at this time. Test them. If any are not programmed, you’ll have to begin the process again and reprogram ALL remotes.

Thanks!!! I want to try your advice but I'm scared. I have one working fob/key and don't want to lose it. I'll decide tomorrow or maybe I'll wait until this weekend:) I will update.
