1. A locking mechanism, comprising:
a latching component comprising a solid latch structure, said solid latch structure comprising a recess;
a locking component comprising a cavity configured to receive said solid latch structure, said locking component comprising a latch-engaging portion rotatably mounted within said locking configured to rotationally transition between a first position wherein a portion of said latch-engaging portion engages said solid latch structure recess within said cavity, and holds said solid latch structure within said cavity, and a second position wherein said latch-engaging portion does not engage said solid latch structure recess;
an auxiliary-access portion rotationally mounted within said locking component and connected to said latch engaging portion, said auxiliary access portion configured to rotationally transition between first and second positions in response to a mechanical force, wherein said first position causes said latch engaging portion to engage said solid state latch structure and said second position causes said latch engaging portion to disengage from said solid state latch structure; and
an actuator operable on said latch-engaging portion to transition said latch engaging portion between said first position and said second position in response to an electrical signal applied to said actuator.
