Does a safe deposit box require electricity to unlock?

Generally speaking, locks using electronic technology such as electronic password locks and fingerprint recognition require electricity to drive their internal mechanisms in order to verify password or fingerprint information and unlock. These types of safes are usually equipped with batteries or external power interfaces. When the battery is low or the external power supply is interrupted, it may be necessary to replace the battery or use emergency unlocking methods (such as a spare key) to open the safe deposit box.
However, for traditional mechanical lock safe deposit boxes, the unlocking process does not require electricity. Mechanical lock safes are usually entered by rotating the password dial. When the password is correct, the lock cylinder will unlock, and the lock of the safe deposit box can be opened using the key. The unlocking process of this type of safe deposit box relies entirely on mechanical structure and is therefore not limited by power supply.
Whether unlocking the safe deposit box requires electricity depends on the type of lock. For locks that use electronic technology, such as electronic password locks and fingerprint recognition locks, electricity is required to drive them; For traditional mechanical locks, they do not require electricity to unlock. Therefore, when choosing a safe deposit box, users should choose the appropriate safe deposit box type and unlocking method based on their actual needs and safety requirements.
