Mechanical safe locks

A tradition of quality

WITTKOPP's mechanical high-security locks impress with their sophisticated mechanics and durability. They are robust, low-wear and extremely reliable. The double-bit key, the trademark of the mechanical safe locks, stands for precise workmanship and special security. Whether you need a classic safe lock, a master key lock or a safe deposit lock, WITTKOPP's product portfolio offers a comprehensive selection of mechanical lock systems
for private and commercial safes.

Criteria for selecting mechanical safe locks

OPTIMA series

With the OPTIMA series, you can quickly meet individual security requirements. From installation scenarios to various bolt options, specific key lengths, and the desired number of keys - everything can be customized to your needs. OPTIMA locks are highly versatile and can be easily integrated into safes up to security grade II.

CABLOX series

CABLOX locks are characterized by their flexibility and easy installation. They can be fixed either on a boltwork or a mounting plate in the cabinet door. A special feature is that they can be fixed with only 2 screw-on points and still provide
a reliable 3-sided lock for cabinets up to security grade V.

SAFELOX series

The SAFELOX series combines the classic WITTKOPP safe locks of classes 1/A to 3/C. These locks are specifically designed for use on boltworks and meet the highest security requirements. Nowadays, they are utilized in a variety of applications,
including safes, ATMs, cash recyclers, and vault room doors.

IVOX series

The IVOX series stands out for its precise and well thought-out design, which makes it possible to use an identical lock case for different certification classes. Whether you install an IVOX Lock class 1/A, 2/B or 3/C, the lock case always maintains the same dimensions. At the same time, IVOX locks impress not only with their first-class workmanship, but also with their attractive design, which is perfectly matched to the solid IVOX keys.


MASTERLOX locks are specifically designed for master key systems and operate on a hierarchical opening principle. With this system, they provide an efficient and secure solution for complex locking hierarchies. The heart of the system is the master key, which serves as the superior key of the locking hierarchy, opening and closing every lock within an installation. This allows authorized individuals with the master key to access all compartments within the system. In contrast, the user key operates only the lock or compartment assigned to it. This assignment allows for a clear distinction of access rights and ensures high security in usage.

DLOX series

WITTKOPP deposit locks prove their worth every day in safe deposit box facilities of financial institutions. With their focus on security and reliability, they offer optimum protection for the clients' valuables. A noteable feature of DLOX locks is the
two-person control: Both a bank representative and the renter of the safe deposit box are always involved in the opening of the lock.

COMLOX series

The robust COMLOX locks are primarily used as rod locks. With their wide, directly locking bolt, they provide the perfect solution for interior compartments and simple safes. In addition to the standard model, the COMLOX 1639 offers enhanced security with an electrical opening delay and release time.


The TRIALOX combines a strong bolt with a robust appearance. Suitable for direct locking, the lock can be easily and quickly welded into the safe using the TRIALOX mounting plate.


The RELOX is a rekeyable and certified safe lock solution that enables you to easily and flexibly adjust the key settings at any time. Whether from the outside or inside, you always have the option to rekey the lock to new keys and optimize your security requirements. With the RELOX, you can maintain full control over access to your safe.
