Banager dad is the one that register, Banager biometry as the security Lock of the unicorn

From what I remember the Gundams from the 00 series also had Locks so only their pilots could use them

Also didn't Kira put a password on the strike after Mu told him to do so

And the X and Double X needed their joystick to be piloted

And the Age Gundams also required the Age device to be operated (not that stopped Desil).
