How do you program infiniti fx35 key?

To program a key for an Infiniti FX35, you typically need to have at least one working key. Insert the working key into the ignition and turn it to the "On" position without starting the engine. Within five seconds, remove the key and insert the new key, turning it to the "On" position as well. Wait for the security light to turn off, which indicates the new key has been programmed. If you have multiple keys, you may need to repeat this process for each one.
