The Łucznik brand security cylinder with the possibility of mechanical recoding is an indispensable element of the investment and the perception of the product, from the point of view of a universal solution combined with cost reduction while maintaining security. I present the solution we call Dual-F below.

The box includes a security cylinder, set of service keys, a safety package with set of Owner’s keys and recoding instructions.

The security cylinder designed by our engineers is tailored to your individual needs, due to its size, security class, color and additional functions, which means that we can offer over 44,000 cylinders’ models. The cylinder’s installation is very simply and requires only basic knowledge on the subject.

We use the first service keys (there can be any number of them - usually two ) and we can make them available to the construction team, investment supervision or keep them for ourselves to control activities on the construction site. It is not possible to make copies of them because they do not have a code card. We can use service keys as long as we need.

In the safety package you will find a code and warranty card and set of 5 Owner’s keys. These are the destination keys, that will be used once all construction work has been completed and are intended for the Owner.

The recoding instructions tell us how to easily deactivate access for the set of service keys. Just insert any of key Owner’s keys in the cylinder and make two full turns, repeat the operation on opposite side the cylinder. This will complete the cylinder’s recoding process.

The advantages of this solution are:

- no need to install a temporary cylinder with only basic security features for time of construction works, that are easy for a burglar to penetrate.

- no need to waste your time to replace the temporary cylinder with security ones.

- guarantee of the quality of the Polish Product

- 30 years of experience of the Łucznik company as a manufacturer.
