Manage keys automatically with RFID

Electronic key cabinets for efficient management, storage, audit and control.

Key assignment and tracking management

Efficient storage

Manual key management is time-consuming error-prone and costly. Keys are easily lost, impacting operational efficiency and security. The more mechanical keys in use, the more difficult it becomes to keep them under control and keep operations running.

Save yourself the frustration, chaos and time-consuming effort of managing your keys.  Create clear and comprehensive control of your keys with Deister's efficient and secure key management solutions.  With the electronic management of keys, access to keys can be established for each user and managed through Deister's Commander Connect software.

Key acquisition and returns are automatically tracked and permanently stored.  proxSafe, the intelligent key cabinet system, provides security and absolute control over operational environments and is fully scalable from four to millions of keys. 

Storage can be customized with multiple cabinet sizes, each with configurable panel arrangements for small key rings to large key bundles.  Electronic key cabinets provide secure 24/7 access and 100% control without costly personal supervision.  Focus on your operations, and let proxSafe focus on your keys.

The right size for every key ring

Both flexx and maxx key cabinets can be individually configured for the required key ring/bundle size with the keyPanel family. All keys are firmly anchored. Access to any key is only possible with  appropriate allocated permissions and user identification. Whenever a key is removed or returned, the authorized slot will signal in red.

RFID key fob

The heart of any key management system is the reliability and flexibility of the electronic tags attached to your keys.

Keytags are attached to a key or key bundle and then connected to with a secure one-time seal. The Keys on that keyTag can only be removed with s special unsealing tool providing an additional level of security. The keyTags each contain a uniquely identified RFID Chip.

The identification of each keyTag is thus completely contactless. Dirt and water have no effect on the reliability of the keyTag which is provided with a lifetime warranty.The keyTags are available in five different colors allowing quick visual group or security loevel identification in additional to the electronic identification.

Benefits of our solution

Maintenance Free

RFID keytags

Your keys are individually tracked with an RFID keytag.  No matter how harsh your operating environment, the keytag will reliably identify your key.  With no metal to metal electronic contract required, no cleaning or maintenance of the keytag is required.

The reliability of these keytags is so high that Deister provides a lifetime, no-questions-asked warranty on all its keytags.

Failsafe Operation

Built-in power and network backup.

Key cabinets will function uninterrupted despite loss of power and/or network connection.  

A built-in back up battery will keep the cabinet functioning up to 72 hours.

The terminals store event data until network connection is restored and the events are then automatically synchronized to the master database ensuring audit integrity.

In the event of catastrophic failure there is a manual emergency release function, to empty the key cabinet.

Status and Audit Reports

All Activity Electronically Documented and Maintained

All key cabinet events are stored and maintained within the Commander Connect software.  These include which users took and returned which keys as well as system maintenance and security events.

A large variety of standard reports are available in Commander Connect.  You can also see reports in realtime with the deisterCockpit application. The reports may also be sent automatically by e-mail as a PDF or CSV file. Specified events may be sent instantly with the deisterGo app.
