Digital locking cylinders for a smarter door

The doorLoxx digital locking system makes it significantly easier and cost-effective to change from a conventional master-key locking system with mechanical keys to an electronic access control system. Installation is very straightforward, no doors are damaged. There is no need for time-consuming and expensive cable installation.

The digital locking components are battery operated and exchange data wirelessly. The digital locking components are available in a variety of formats, for example cylinder and Digital Handle. Our portfolio includes an updater, controller and online reader, which link the locking components to the system. Full scalability makes it possible to operate a system without PC software as equally as with Commander Connect, which offers all the performance characteristics of professional access control systems.

Benefits at a glance

Long battery life

The energy management system (patent pending) makes possible a battery life of 5 years with as many as 90,000 activations. That reduces running costs.

No cables

No cables need to be laid to the door, because the digital locking components communicate via “Cardnet” and wirelessly.

Adaptable on-site

It is possible to adapt the installation depth of the digital cylinder on site. Spacer washers make it possible to vary the length.

All inclusive

A high-precision quartz crystal clock to ensure perfect time control as well as a long-range radio module are standard in all reader heads.


The reader technology and mechatronics are separated from one another. That means the reader technology can be replaced at any time.

Made in Germany

All products are „Made in Germany“. Their function and quality are developed, produced and tested to the highest standards.


Energy-saving wireless technology

airLink is the deister wireless standard designed to integrate digital locking components and an updater into a system by means of wireless transmissions. Sophisticated energy management ensures very little drain on the battery. This allows the digital locking components to regularly exchange data, receive new access rights and transmit their own access log to the system. At the same time all data is secured by powerful 128 bit AES encryption.

It is possible to achieve ranges up to 30 m indoors, and as much as 100 m outdoors.

  • Very low power consumption
  • 128 bit AES encryption
  • Strong wireless range

The doorLoxx portfolio of digital locking components covers a variety of formats to offer the right solution for all doors and applications.

All digital locking components are based on the same technical concept: the mechanics are separated from the reading technology. The electronic for the reading technology is in a reading head that is the same in all locking components and can easily be exchanged. That way it is easy to keep the system up to date and secure.

The battery life is the same for all digital locking components and lasts for 5 years with 60,000 activations or a standby of 10 years or 100.000 activations in a shorter timeframe.

All digital locking components are equipped with our radio connection airLink, which can be used for the „heart beat“ or to download the events and manage online the access rights in all looking components.

1 Digital Cylinder

The Modern Lock of the Future

The digital cylinder is installed in precisely the same manner as a mechanical cylinder in just a few simple steps. Because the design size is identical nothing needs to be adapted, drilled or altered. The basic bodies can be ordered in 5 different installation lengths plus a half cylinder; it is possible to adapt their length with the use of profiled spacers when installing. That means it is possible to realize lengths from 30/30 to 45/75 in 5 mm steps using muliple profiled spacers.

Benefits at a glance:

  • Installation length can be adjusted on the spot
  • Best quality made in Germany
  • Best in class reading performance

2 Digital Handle

Works on any Door

The slim and straightforward design of the Digital Handle ensures it will grace any door. Four different models are available to choose from, depending on the form of the handle. When installing it is possible to make use of the same drilled holes as used for conventional fittings.

The cover plate facilitates parallel usage of the existing cylinder to reliably lock the door or to elegantly cover the cylinder opening. The exchangeable cover plate makes it possible to adapt the installation on doors with different distances between the handle and cylinder. An approach that ensures the Digital Handle fits perfectly on every door, no matter if it is full panel or tubular frame door.

Benefits at a glance:

  • Works on any door
  • Slim and elegant design
  • Additional tamper connect over airLink Easy battery change

3 Digital Lock

Security meets Design

The digital lock is developed for self-locking locks and combines security with an attractive design. The minimalistic design allows to seamlessly integrate with the design of the door handle to give maximum freedom of choice of shape and colour.

On top of that the digital lock offers more security, because even if damaged or forcefully removed there is no access to the mechanics of the locking mechanisms which is inside the door.

Benefits at a glance:

  • Maximum design freedom
  • More security
  • Encrypted lock control

4 Digital Strike

Online and Offline Combined

The digital strike offers the same door control and door monitoring functionality as an online access control with all the benefits of an offline system. It has two in- and outputs that can control the door alarm or door contact for example. It is powered by a local power supply and can be flush-mounted.

The digital strike can be operated wirelessly via Cardnet or airlink and no cables for data communication are needed.

Benefits at a glance:

  • Online functionality with the benefits of offline access control
  • Compact design for easy installation
  • Existing components can be reused

Reading Technologies

Keep your System up to date


Our digital locking system supports all popular reading technologies as well as passive and active transponders. The reading technology is separated from the other electronics. It is mounted in a reading head and can be exchanged easily.

All reading heads have the same formfactor. Therefore also systems with different formats of digital locking components the reading technology can easily be exchanged without having to replace the complete hardware.

Benefits at a glance:

  • All popular reading technologies are supported
  • Easy exchange of reading technology
  • System can stay up to date without much effort or cost

Offline system with online features

Access control with Cardnet

In larger systems in particular, offline components are quickly stretched to their limits. The more users and doors there are, the more data needs to be stored, managed and distributed. The Cardnet concept from deister electronic time stamps and stores access rights, time profiles and calendar profiles on the user’s credential. This ensures the offline locking components are secure regardless of the size of the system and the number of users. The core Cardnet components are the update reader and update stations. These are installed at key positions such as at building entry points, which in turn are connected to the system either by cable or airLink. The user must update their credential at that point of entry every day, before being granted access to the doors.

When using offline components the validity of the time stamp is checked first, then the access rights and time profiles are checked before access to the door is granted.

In addition to update readers and update stations with an integrated display, the portfolio also encompasses standard online readers. With a well-thought-through combination of update readers, online readers and offline locking components it is possible to economically and securely implement a whole system that can be expanded at any time.
