What is the purpose of an internal relocking device in a safe lock case?

  1. To allow easy access after an attack

  2. To prevent the lock bolt from being retracted after an attack

  3. To provide additional combination security

  4. To enable digital control of the lock

The correct answer is: To prevent the lock bolt from being retracted after an attack

An internal relocking device serves a critical safety function in a safe lock case. Its main purpose is to secure the lock mechanism in the event of an unauthorized attempt to manipulate or access the safe. When an attack occurs, such as drilling or forced entry, the relocking device activates, preventing the locking bolt from being retracted. This ensures that even if the safe's primary locking mechanism is compromised, the contents remain protected. The relocking device acts as a safeguard, enhancing the overall security of the safe by making it significantly more difficult for intruders to gain access. This feature is crucial for maintaining the integrity of the safe during a breach attempt, thereby emphasizing the importance of security features in safe design.
