In certain embodiments, the present invention includes a key for engaging a locking mechanism for a port cover for use in a system integrated into a structure for injection of a material into one or more cavities in the structure. The locking mechanism is for removably securing a cover of the port cover to a base of the port cover that is coupled to the structure and includes one or more ports for injecting material into the one or more cavities in the structure. The key is adapted to engage with the locking mechanism, and orient the locking mechanism such that the locking mechanism engages with a projection of the base to removably secure one or more tabs of the cover in engagement with one or more corresponding slots of the base to removably secure the cover to the base to prevent unauthorized access to the one or more ports.
