Mechanical locks
The Rulebook
European Standards
On the basis of the European standards EN 14450 and EN 1143-1, cabinets are tested and classified into safety levels or resistance grades. This classification also determines the number and lock class of high-security locks to be used.
Double-bit locks from WITTKOPP exceed the number of locking differences required by the EN 1300 and VdS 2396 standards in every lock class. In other words, WITTKOPP locks are much more secure than required. Depending on the number of locking differences achieved, the double-bit locks are assigned to different security classes.

Lock assembly
Frame work or direct
In the case of mechanical safe locks, a distinction is made between locks that are mounted on a transom mechanism and locks that are welded directly into a cabinet door.
Timber-frame locks are particularly suitable for safes with high security requirements, e.g. safes, ATMs or cash recyclers. The frame work is the central connecting element between the safe lock and handle.
Triggered by the opening of the lock, the bolt mechanism releases the blocked safe handle. The rotational movement of the handle moves vertical and horizontal sliders and opens the vault door.
Boltwork required
Direct locking
If a transom system is dispensed with, this is referred to as directly blocking safe locks. With this type of lock, a mounting plate or the lock ceiling is welded directly into the door and then the Lock or the lock platform screwed to the ceiling. Direct locking safe locks are very cost-effective and are usually used in simple safes of security levels S1 and S2, for example in gun safes, furniture safes or wall cabinets.
The lock installation position
Right or Left
If the flap hinges are located on the left side of the safe (hinge side on the left), it is a left door and therefore a left door should be used. Lock be installed. The key must then be turned counterclockwise to open the lock.
In most safes, the flap hinges are located on the right side (hinge side on the right) and they therefore have right doors. In order to achieve a right Lock , the key must be turned clockwise until it stops.
The variants
Keyed alike or removable
Keyed alike refers to a group of locks that can be opened by identical keys.
In the case of certified safes, the key is not removable when open. It remains in the Lock. However, in the case of removable locks, the key can be opened when the Lock and stored safely in a separate location during opening hours.
Both variants do not have certification.
The double-bit key
Finishes and materials
The double-bit key is the hallmark of mechanical safe locks. It stands for precise workmanship and special safety. WITTKOPP double-bit wrenches are available in different designs and materials. The door thickness of the safe and the closing frequency of the lock should be taken into account when choosing the keys.
For strong doors, hook-in or articulated keys are particularly suitable, as they offer a high level of storage convenience. Whereas in the case of hook-in wrenches, the
The key can be kept separately from the rest of the key, the articulated key can be folded to about half its total length.
If a Lock frequently opened and closed, keys made of tombac or nickel silver should be used. Due to their material properties, these keys are particularly wear-resistant.

The master key lock
Overarching opening principle
Locks for main locking systems, also known as HS locks for short, work according to a higher-level opening principle. The master key opens and closes as the parent key of the lock hierarchy of each Lock of a plant. The user key, on the other hand, can only contain the individual Lock or compartment.
The Rental Safe Lock
4-eyes principle
Rental locker locks are always operated by 2 people. Depending on the lock design, a bank employee locks the Lock first manually or electrically approved. Only then can the tenant Lock with his key.
With WITTKOPP rental locker locks, the bank and tenant locks are stacked on top of each other, so that the Lock can only be operated via a keyhole. This lock design means that the bank key can be removed in the mechanical version. However, the tenant key remains in the Lock. If the tenant locks the locker, the bank lock is automatically locked as well.
