Electronic lock cylinders do not use traditional keys. Instead, access authorization is managed digitally – access is granted through a corresponding card, smartphone, or RFID key fob. In the event of losing this medium, access authorization can be promptly deactivated and blocked. Furthermore, there's no need to replace the entire locking system. Ultimately, this allows for more reliable access control and compliance with current security requirements. The data can also be used for further analysis as needed.
