It typically involves the use of two independent locks, often of different types, applied simultaneously or successively for added security and assurance.
Typically, a double lock system functions by requiring the engagement or activation of two separate locks, each offering its own unique level of security. This may involve the use of two physical locks such as padlocks, deadbolts, or combination locks, or a combination of physical and digital locks such as biometric scanners or keycards. The idea behind a double lock is to increase the difficulty and time required to bypass or tamper with the secured item, thereby enhancing its protection.

By requiring two different locking mechanisms to be bypassed or opened, a double lock adds an extra layer of defense against unauthorized entry or access.
