Whatever you need, we support you. Make use of it, we look forward to hearing from you!


Benefit from the experience and knowledge of our system consultants and technicians. We are at your side. From the small locking system for an apartment building, to extensive access control systems, kindergarten escape door solutions, emergency exit and escape route technology, to complete security concepts and cost/benefit analyses in large-scale projects.

Simply send us pictures, e.g. of your object, the door, the cylinder or even your locking plans by e-mail without obligation. We would be happy to advise you on the implementation options – either by telephone or on your premises.


Doors have to meet a wide variety of requirements. Your own requirements and the applicable legal regulations on fire protection, sound insulation, burglary protection, escape and rescue route specifications often conflict with each other. Our employees, specially trained in this area, take into account the purpose of each individual door and reconcile different requirements.

This is rarely achieved with a single product or manufacturer. Zweygart will find suitable, intelligent combinations from different manufacturers for you and you will receive a powerful, tailor-made overall concept. Because with our professional composition of locks, handle sets, fittings, locking systems, means of identification and control devices, legal requirements can be fulfilled and defined requirements implemented in accordance with the latest state of the art.


Our technicians measure the values required for each product, precisely and reliably. Whether cylinder dimensions, lock dimensions, fitting variants, protective shields. All relevant parts are checked, measured and documented by us, interfaces to other trades are established. This way you can be sure that everything is correct during installation.


The devil hides in the details. To achieve the best possible overall package for your project, we work together with selected manufacturers from Germany, Austria and Switzerland. For special solutions, our employees review various catalogues, technical descriptions and data sheets, search for alternatives, make comparisons and talk shop with the technicians.

We look forward to being your partner and will be happy to take time for you!


Most companies have their own IT department, which plays installations and updates on the company computers. We therefore think it makes sense to involve your IT in the project as early as possible. Our technicians work with your IT staff, send them all the necessary information about the respective program, discuss which hardware and software the solutions you have chosen require and which points need to be observed with regard to data protection and data backup.


Electronic locking systems are usually delivered unprogrammed and configured in your company. We are trained in the systems of various manufacturers.

Creating doors, importing personal data, setting up devices and identification media in the software, defining access times – we are happy to do that for you if you wish. In this way you have a fully equipped, fully functional system right from the start. If electronic systems are still in their infancy, or if your digital locking system is not very dynamic, then it is worthwhile to have your new system managed by us. The software and thus your system are always up to date. Find out more under administration by Zweygart.
