I think you can start a scrambler without the chip in the key (or a malfunctioning chip), but you still need the key. The Pin Code is just in case your RFID chip fails in the key. Now my XDiavel allows me to start the bike without the key, but it has a keyless FOB.
I am not sure about the 1100, though. Maybe it is like my XDiavel and has a keyless FOB.
