The rules and regulations
European standards
Lockers are tested on the basis of the European standards EN 14450 and EN 1143-1 and classified into security levels or resistance grades. This classification also determines the number and lock class of the 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 significantly more secure than required. The double-bit locks are assigned to different security classes depending on the number of locking differences achieved.

The lock assembly
Boltwork or direct
With mechanical safe locks, a distinction is made between locks that are mounted on a boltwork and locks that are welded directly into a cabinet door.
Boltwork locks are particularly suitable for secure storage units with high security requirements, e.g. safes, ATMs or cash recyclers. The boltwork is the central connecting element between the safe lock and the handle.
Triggered by the opening of the lock, the boltwork releases the blocked safe handle. By turning the handle, vertical and horizontal slides are moved and the safe door is opened.
Boltwork required
Direct locking
If a boltwork is dispensed with, this is referred to as a direct locking safe lock. With this type of lock, a mounting plate or the lock cover is welded directly into the door and then the lock or the lock platform is screwed to the ceiling. Direct locking safe locks are very cost-effective and are usually used in simple secure storage units of security levels S1 and S2, for example in gun cabinets, furniture safes or wall cabinets.
The lock installation position
Right or left
If the flap hinges are on the left-hand side of the secure storage unit (left-hand hinge side), the door is on the left and a left-hand lock should therefore be installed. The keys must then be turned counterclockwise as far as it will go to open the lock.
On most secure storage units, the flap hinges are on the right-hand side (hinge side on the right) and they therefore have right-hand doors. To open a right-hand lock , the keys must be turned clockwise as far as they will go.
The variants
Keyed alike or removable
Keyed alike refers to a group of locks that can be opened using identical keys .
In the case of certified secure storage units, the keys cannot be removed when open. It remains in the lock. With removable locks, however, the keys can be removed when the lock is open and stored securely in a separate place while the lock is open.
Both variants have no certification.
The double-bit key
Designs and materials
The double-bit key is the hallmark of mechanical safe locks. It stands for precise workmanship and special security. WITTKOPP double-bit keys are available in different designs and materials. The door thickness of the safe and the locking frequency of the lock should be taken into account when selecting the keys .
Detachable or hinged keys are particularly suitable for strong doors, as they offer a high level of storage convenience.
With detachable keys, the key bit can be stored separately from the rest of the key, whereas the hinged key can be folded to approximately half of its total length.
If a lock is opened and closed frequently, 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
Overriding opening principle
Locks for master key systems work according to a higher-level opening principle. As the higher-level keys in the locking hierarchy, the master key opens and closes every lock in a system. The user key, on the other hand, can only open the individual lock or compartment assigned to it.
The safe deposit lock
Dual-control principle
Safe deposit locks are always operated by 2 people. Depending on the lock design, a bank employee first locks the lock manually or releases it electrically. Only then can the renter open the lock with their key.
With WITTKOPP safe deposit locks, the bank lock and and the renter lock are positioned one above the other, so the lock is operated through a single keyhole. This lock design requires that, in the mechanical version, the bank key can be removed, while the renter key remains in the lock. When the renter locks the compartment, the bank lock is automatically secured as well.
