Safe Locks App

Challenge

When thinking about systems that must meet the highest security requirements, ATMs often come to mind first.
However, existing hardware-based solutions incur high maintenance costs, require complex manual configurations, and still do not provide an adequate level of security.

dormakaba, one of the world’s leading providers of security and access solutions, therefore faced the challenge of delivering state-of-the-art and secure ATM systems – while ensuring operational efficiency and scalability.

Solution

In close collaboration with dormakaba, SABO Mobile IT
developed a highly secure and scalable software platform: the Safe Locks App, available for iOS and Android.

The app enables the digital, controlled, and efficient management of electronic safe locks – worldwide.

How a product family evolved

From the very beginning, SABO Mobile IT pursued a clear goal: maximum scalability and long-term investment security.

  • Launch with the first lock model: CenconX
  • Seamless integration into the dormakaba backend (management and distribution of access codes)
  • Expansion to include another lock family: Strato
  • Support for different firmware versions from various providers
  • Future-proof expandability, e.g., for the Apexx lock –without fundamental system modifications

The underlying architecture is designed to be flexibly expanded and operated over the long term.

To ensure the reliability of this complex ecosystem, a comprehensive automated testing strategy was developed, including hardware-in-the-loop and backward compatibility tests.

Firmware integration – in-depth technical expertise

In addition to developing the Safe Locks app, SABO Mobile IT assumed overall responsibility for integrating the CenconX firmware, provided by our partner Consilia Brno s.r.o.

Key firmware functions:

  • Control of physical locking mechanisms
  • Implementation of complex security requirements directly at the device level
  • Automated testing infrastructure within a CI/CD pipeline

This ensures stable releases, rapid further development, and an uncompromisingly high level of security.

Results

The Safe Locks solution has evolved from a standalone solution into a powerful platform.

Concrete benefits for users of the Safe Locks app:

  • Significantly reduced on-site service times
  • Sustainable reduction in operating costs
  • Minimization of manual errors

In addition, the platform opens up new business opportunities – particularly in dynamic markets such as India and Brazil, where secure and efficient ATM infrastructures are essential.

The software replaces insecure manual processes with a consistently secure, modern architecture:

  • Connection to the lock via smartphone using encrypted Bluetooth Low Energy (BLE)
  • Use of modern authentication methods (e.g., one-time codes) to ensure that only authorized users have
    access
  • End-to-end encryption of all commands between the app, the lock, and the backend
  • Centralized, traceable, and audit-proof logging of all actions
  • Location-based access control (geofencing) – access only within defined geographic areas
  • Global availability through native apps for iOS and Android

The result: a fully digital, secure, and controlled process –without media breaks.
