Mechanical locking systems

Individual security for every building

Overview of mechanical locking systems

Mechanical locking systems stand for quality, durability, and reliable security in daily use. Precisely manufactured locking cylinders provide effective protection against manipulation and unauthorized access. Our master key systems enable secure, user-friendly, and economical access control for private homes, businesses, and public buildings. The matching keys are manufactured with precision, ensuring reliable and trouble-free operation. Thanks to their modular design, mechanical locking systems can be flexibly adapted to individual requirements – from simple single locks to complex master key systems with defined access rights. Whether for new construction or modernization: our mechanical locking systems are a proven solution for building protection and controlled access – robust, precise, and durable.

Security and flexibility

Reversible key systems

Our reversible key systems offer reliable security, high durability, and convenient operation. Thanks to double-sided locking regardless of key orientation, they are ideal for use in both private and commercial settings. The robust locking cylinders are precisely manufactured. The long patent term and additional key copy protection versions provide effective protection against unauthorized key duplication. Existing master key systems can be easily expanded or modernized. Whether for single-family homes, offices, or industry – with a mechanical locking system, you are choosing a proven solution that combines protection and flexibility.
