I have few concepts in my own Mecha Compendium doc for locking security features including I think a security measure that upon a failed access/activation the mecha locks the cockpit and releases a lethal/non-lethal gas either killing or knocking unconscious the pilot... another activates the power core in an overload mode destroying the mecha and x-feet surrounding it to prevent its technology and databases falling into enemy hands... another I think was a removable drive that when installed loaded the pilots configuration into the mecha's OS allowing for easier rotation between a mass produced line of mecha.
