Lock C for USM Haller

With the new electromechanical lock C and the specially developed USM app, storage space and lock management take on a whole new dimension. Thanks to its dual technology (RFID & Bluetooth), the lock can be operated easily using a key card or a smartphone, via the intuitive, user-friendly app.

Connectivity – up to four user modes offer a variety of new applications

Thanks to its four user modes, the lock C is ideal for meeting different and changing requirements.

Public Locker mode

A row of lockers is available to several users – they simply choose a free locker and lock it using the card or the app. Ideal for temporary usage in open spaces, for desk sharing or as a cloakroom in reception areas.

Personal Light Locker mode

A key card is permanently assigned to a locker. This prevents the locker from being locked by another user.

Personal Locker mode

The same locker is assigned to a certain person for a long time. As such, the locker owner can safely store their personal and confidential documents there.

Shared Locker mode

If one person is absent, access to the locker can be shared with selected individuals. For teams or project groups, one locker can be used as a shared storage location.

Easy retrofitting

As with all USM system parts, the new lock C can be retrofitted into your existing USM furniture in keeping with the backward compatibility principle. The existing handle or lock handle can simply be replaced with the new lock C without having to replace the whole door.

Cleverness – high-tech in a simple design

The lock C combines electronics and mechanics, both produced to the usual highest quality. Compact and in line with the timeless aesthetics of the design classic.

Clear and simple management

With keys it’s always the same – you wonder where you last put them … or which key goes with which locker … and how to organise the management of lockers and their keys among employees…


The USM app gives users a clear overview and is easy to use. For the administrator, it serves as an intuitive tool not only for organising the locks, but also for keeping an eye on the battery level, updates and log files.
