Fob and key in fob question

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.
