I am using an x100 pad2 to try and program a 2017 Toyota Camry. I said "try" because I cannot program the key I have cut for the vehicle. The key I cut opens the doors, and turns the ignition cylinder; however, I cannot have it programmed because I do not have a sub-master key. I am wondering what is a sub master key? I saw a video for a 2015 Camry, and the locksmith, programmed a remote first. I don't know if this was to make a sub-master key first or if the key was already preprogrammed and he just wanted to program the remote first. But please let me know. Also, I could not locate the 'reset IMMO' button after I selected Type H chip in my programmer. Any reason as to why this option is not available in my pad2?
