SAFELOCK SYSTEMS LTD IS A distributor of high security locks for safes and secure storage units. The company stocks locks from manufacturers such as LAGARD, KABA, Tecnosicurezza, Stuv and Wittkopp.
Directors Jasmine Hunt-Brown and Tony Brown tell us all about safe locks.
SAFES
An insurance graded safe or vault door has many mechanical components, bolts, pins and springs( boltworks) which allow the door to be secured at several different points, strengthening protection against attack. Boltworks are fitted in conjunction with one or more safe locks, which can also work with relockers – designed to secure the safe if the lock is attacked.
Safe locks generally conform to the
same size and footprint, which allows a safe manufacturer to offer the same model of safe, with different locking options for the end user, depending on their needs.
As with safes, Safelocks are subject to
KEYLOCKS
The most basic and economical method of locking a safe is to use a
KABA Mauer Keys
Keylock. Certified Keylocks use levers turned by a doublebitted key, which release blocking elements and pull the bolt into the lock body.
Lever pack: KABA Mauer President Keylock
KEYLOCK FEATURES:
• Simple and economical
• Allows multiple users to each hold a key, but there is no identification of who has opened the safe
• The key is retained in the lock and cannot be removed until the lock is closed
• Risk of lost or stolen keys
WHEEL COMBINATION LOCKS
LAGARD 3390 3-Wheel Combination Lock
WHEEL COMBINATION LOCK FEATURES:
• No risk of stolen keys
• The code can be changed if it is compromised
• There is only one code, and so if multiple users require access to the safe, it must be shared. There is no identification of who has opened the safe.
• Users must remember to turn the dial to close the lock
ELECTRONIC COMBINATION LOCK
An electronic combination lock requires users to type in their code. When a correct code is entered, a motor within the lock body releases blocking elements and allows the bolt to be either pulled or pushed into the lock body.
Electronic Combination Locks generally comprise the entry or keypad, the lock body, and a battery pack or power supply.
Electronic locks are available with several different bolt types which are used according to the construction of the safe boltwork:

LAGARD 1777 Dial

standards regulation, and for Europe, the standard is EN1300.
A wheel combination lock requires the user to dial in their code – with one set of digits for each of the wheels. The dial is turned back and forth to the correct code which ultimately positions all of the wheels to allow a lever to release blocking elements, and pull the bolt into the lock body.
The bolt is swung open by boltworks, and closes automatically when the boltworks are released.
