The Automatic Prodecoder opens and decodes the Technomax 4×4 double-bit lever lock quickly and accurately.

Since this Prodecoder model targets the Technomax 4×4 system, it matches the lock’s internal layout exactly. The tool uses a blade with two cassettes, and each cassette carries four separate pins. These cassettes connect directly to the back wheel through a responsive pumper mechanism, which creates smooth and predictable control.

As you can see in the image below, the blade follows the shape of the patented safe key. Therefore, you never need to remove the internal “bulges” on the front or back plates. Instead, the tool enables a clean, efficient, and completely non-destructive opening.

In practice, the mechanism works through a simple sequence: once you rotate the back wheel and start pumping, the pumper moves forward and immediately drives the cassettes. The pins then press against the levers and lift them to the heights required by the lock’s unique code. The movement continues until the pins reach the exact positions that match the key’s original teeth. Consequently, the lock opens smoothly and without damage.

Moreover, the Prodecoder maintains a fully non-destructive approach throughout the entire process. Each model fits one specific lock type—here, the Technomax safe lock or others with identical internal dimensions. Because of this, you must know the lock’s exact measurements before using the tool. Additionally, the number of levers and the spacing between them determine whether the tool will operate correctly.

Important:
Use the blade gently. Apply only minimal tension so the pins can move freely. Excessive force can damage the mechanism and may break the blade.
