1. A method of operating a thrust reverser tertiary lock, comprising:
configuring, while in an escaped configuration, a barb at a first end of a shaft of a probe to a first configuration;
locking the thrust reverser tertiary lock by:
contacting the barb to an edge of an aperture defined in an end wall of a receiver shaped to accommodate the barb;
urging, based on contact between the barb and the edge, the barb from the first configuration to a second configuration;
penetrating, by the probe, the aperture;
reconfiguring, after the barb has passed through the aperture, the barb to the first configuration; and
preventing, by the end wall, escapement of the barb through the aperture in the first configuration; and
unlocking the thrust reverser tertiary lock by:
configuring the barb to the second configuration; and
permitting escapement of the barb through the aperture in the second configuration.
