|3 button Nissan remote with FCC ID KBRASTU15|
Some consumers actually think that they can gain a remote function by replacing their 3 button remote with the 4 button one, wrong. If your vehicle came with a 3 button remote, you will not be able to turn it into a remote start vehicle simply by getting a related 4 button remote with a remote start button. Most consumer think that matching the FCC ID of the original and replacement remote is the only thing they need to do. It is indeed correct in many cases but not all the time.
