A mechanical and an electronic timelock

A time lock (also timelock) is a part of a locking mechanism commonly found in bank vaults and other high-security containers. The time lock is a timer designed to prevent the opening of the safe or vault until it reaches the preset time, even if the correct lock combination(s) are employed.

Contents

Time locks are mounted on the inside of a safe's or vault's door. Usually there are three time locks on a door. The first one to reach 0 will allow access in to the vault; the other two are for backup purposes.

Time locks were originally created to prevent criminals from kidnapping and torturing the person(s) who knows the combination, and then using the extracted information to later burgle the safe or vault, or to stop entry by authorized staff at unauthorized times. [1]

An early test of their effectiveness came on May 29, 1875 in Great Barrington, Massachusetts, when a gang of robbers took the family of banker Frederick N. Deland hostage, demanding that he open the vault of the Grand Mahawie Bank. They were thwarted by a time lock which had been installed only a few days earlier, and left without harming the captives. [2] [3] [4]

Modern electronic time locks have some functions not available to mechanical time locks, like resettable timers and pre-set times to activate. [5]

A safe is a secure lockable enclosure used for securing valuable objects against theft or fire. A safe is usually a hollow cuboid or cylinder, with one face being removable or hinged to form a door. The body and door may be cast from metal or formed out of plastic through blow molding. Bank teller safes typically are secured to the counter, have a slit opening for dropping valuables into the safe without opening it, and a time-delay combination lock to foil thieves. One significant distinction between types of safes is whether the safe is secured to a wall or structure or if it can be moved around.

A time-delay combination lock is most commonly a digital, electronic combination lock equipped with a delay timer that delays the unlocking of the lock by a user-definable delay period, usually less than one hour. Unlike the time lock, which unlocks at a preset time, time-delay locks operate each time the safe is unlocked, but the operator must wait for the set delay period to elapse before the lock can be opened. Time delay safes are most commonly used in businesses with high cash transactions. They are used in some banks including Nationwide, HSBC, Barclays, and Halifax.
