A securilock, also known as a security lock, served as an access control mechanism, preventing unauthorized entry to sensitive locations. The Galactic Empire made widespread use of these security measures. Typically, security locks unlocked upon receiving the correct authorization code, often transmitted through a code cylinder utilizing a scomp link; however, certain models permitted manual code input. Other types of security locks relied on biometric authentication methods such as retinal scans, fingerprint recognition, or voice analysis to verify the user's identity. Only a limited set of tools, including electronic lock breakers, anti-security blades, and electroshock probes, were capable of bypassing a security lock's defenses.
Security locks incorporated a wetter plate in their construction, and boreen was among the materials used in their manufacture.
