Control who can have access to which keys and when
Identify, control, audit and report
Keys remain a vital part of any security solution yet their importance is often overlooked. They control access to critical areas and high value equipment. An electronic key management system can restrict which people are allowed access to individual keys, it is an access control system for keys. Knowing who took the keys when and where they are now means you are always in control and people feel more accountable resulting in less lost keys. Implementing a key management system can reduce operational costs and resources by eradicating the manual issue and return of your keys.
Our modular and scalable key management systems offer intelligent control, administration, and documentation of your keys – flexibly and from anywhere. proxSafe creates the highest degree of efficiency and comfort in your everyday operations.

maxx
Compact and elegant key box with automatic door

The maxx cabinet allows full control over your keys whilst giving quick and easy access to keys when needed. The convenient and ultra reliable automatic roller shutter door keeps keys hidden from view and allows the cabinet to be located in areas such as a corridor where a conventional hinged door would be problematic due to space. Available in 32 or 64 keyTag capacity Maxx cabinets can be combined with other maxx or flexx cabinets where additional storage space is required and multiple cabinets can all be managed by the same control terminal.
flexx
A scalable modular system
Flexx cabinets are available in a matching range of different sizes with a choice of either a solid steel or window door. The modular design allows a system to be easily adapted specifically for your current needs whilst leaving options open for future needs. Select a cabinet size, select keyTag panels and finally select a control terminal to meet your exact requirements. A variety of different internal keyTag panels allows each cabinet to be optimised to suit the different sizes and bunches of keys that are to be controlled. A system can be configured for maximum capacity by only using the wider spacing keyTag panels for those large bunches of keys that need more space. The keyTag panels can also be changed as needs change.
Equally the flexx cabinets allow you to invest in a system for today that leaves your options open for future expansion. Multiple cabinets can be connected together and managed by the same control terminal of your choice. You can add additional cabinets or keyTag panels at any time.

Radisson Blu Hotel, Hamburg Airport
Security solutions for hotels
In the Radisson Blu Hotel at Hamburg airport, a modern electronic key management system supplied by the RFID specialists deister electronic is providing more security, efficiency, and transparency in the handling of mechanical keys.
Project target
Electronic key management, 24/7 availability of all keys, protocols of all key removals and returns, access restriction, and individual assignment of removed
keys.
Challenge
For a certified Safehotel, there are especially high security standards in the annual audits.
Solution
The proxSafe RFID-based key management system with the Commander Connect management software.
Advantages
Audit security, fast, uncomplicated personnel-free key release, transparency, no delay in checking in and out, noticeably less burden for staff, resulting in costs savings and faster return on investment.

Whether as a stop-over for cruise ship or airline passengers, a location for business meetings, or an attractive accommodation for visitors to the city: The Radisson Blu at Hamburg airport impresses with personal service and luxurious facilities. 266 modern, fully-equipped rooms provide all the amenities expected of a state-of-the-art business hotel.
Sebastian Herzog, General Manager at the Radisson Blu Hotel, knows: ‘For completely satisfied guests you need not only top service and personalised offers, but also perfect coordination and cooperation between the different hotel departments. In this process, up-to-date technology plays a decisive role.’ In the Radisson Blu, this is also true in key management for security-relevant areas.
In the past, mechanical keys for the sprinkler system control room, for technical and utility rooms, staircases, conference and meeting rooms, or fitness facilities used to be handed out manually. In the process every single key movement had to be thoroughly documented in the key book. Sebastian Herzog remembers: ‘In the course of a hectic hotel working day, bookings were repeatedly left incomplete. If keys were lost, you had to do a painstaking search for them, and in the worst case, entire locks had to be replaced. Even less practical was that by handing out keys to our staff or outside contractors, the guest’s’ checking in and out was delayed unnecessarily, and the procedures at the reception and in the administration were disrupted.’
In order to optimise internal processes and to raise the security level, the hotel looked for a reliable, intelligent, RFID-based system (Radio Frequency Identification), with which every key removal and return is automatically monitored and, for legal certainty and audit proof, completely documented. The appropriate specialists were found at deister electronic GmbH in Barsinghausen. To quote Sebastian Herzog: ‘The deister electronic team convinced us right from the first presentations of the qualities of their proxSafe solution.’
A solution which fits precisely
‘Our very lively hotel operations naturally do represent something of a challenge,’ sums up the Hotel Manager. ‘Here, everything has to run quickly in the interests of our guests. So we cannot afford to have inefficient internal processes. Which is why we are so satisfied with the non-contact RFID solution from deister electronic, which is exactly tailored to our company. It does not only take pressure off the staff and avoid delays. The system also offers a clear advantage through automated documentation processes, more security, and transparency. These aspects are, for a Safehotel such as ours, naturally particularly important.’ And last but not least, the workflow optimisation also means a reduction in working hours for his team, and thus costs savings which lead to a fast return on investment.
Certified security

The Radisson Blu, Hamburg Airport, which belongs to the Carlson Rezidor Hotel Group, was awarded the Safehotels certificate in 2015. With this, hotel guests are ensured constantly high quality in terms of security procedures and programmes.
