It’s not recommended to access a lock with multiple smartphones the same time. Due to limitations in Bluetooth protocol, the list of available lock devices within the app may be incomplete in case multiple mobiles are accessing a single device at the same time. Also lock devices may be blocked when other devices try to access them at the same time.

Multi language support

Currently the app supports English and German language. By default, the okey smartphone app uses the default language of your smartphone. If the language setting of your smartphone is neither set to English or German, the okey smartphone app will use English language.

Using the okey Smartphone App

Since access rights to locks are granted for a certain period, please make sure that your smartphone has correct time and date settings.

Locks Screen

After successful login, the app is automatically searching for lock devices of the provider in reach via Bluetooth. The maximum reach distance of Bluetooth signal is theoretically up to 10 meters outside buildings. The range will be drastically reduced by walls or other disturbances inside buildings.

Lock Devices List

At the lock devices list by default all locks are listed which are in Bluetooth reach of your smartphone and which you are allowed to open.

Bild: lock-devices

If no locks are in reach, you should move closer to the lock and press the rescan button. Also, if some locks are generally found but the one lock you want to open is missing, you should also move closer and press the rescan button.

Also, by default only locks which you are allowed to open are listed. If you can’t find your lock, please disable the setting ‘only my locks’ to verify that the app is finding the lock and the access right is missing. You can find this setting by clicking the gear wheel icon to the top right.

Open Locks, Request Access

To open or close a lock just press the open or close button right beside the lock name. If you have no active access right to a lock, please contact your local administrator.

Depending on the type of lock and lock settings, some locks close automatically after some seconds (e. g. wall readers) and some locks remain open (e. g. keysafe locks).

Please make sure that the lock is closed, before leaving the lock.

By default, the mobile app needs internet connection to open a lock device. Depending on your provider settings access rights to lock devices may be stored locally in the mobile app for a certain time, so that you may be able to open dedicated locks without internet connection.

Lock Details

By selecting a lock, a screen with the technical lock details will open.

To get back to the Lock Devices Screen press the back icon on the upper left.

Allow Geolocations

Depending on your provider’s settings, when oppening or closing a lock, the okey smartphone app sends the geolocation of your mobile device to the Secure Cloud Core to locate mobile locks like padlocks or bike locks. You can aggree or disagree to send the geolocation to your provider when starting to use the app.


History Synchronization

After you opened a lock, the okey smartphone app will synchronize lock data from all locks in Bluetooth reach to the Secure Cloud Core backend. Also, the battery power level of each lock device in reach will be transmitted to the Secure Cloud Core backend. During history synchronization, due to technical restrictions of Bluetooth protocol, all locks are deactivated in the okey smartphone app just for a few seconds to avoid interferences of Bluetooth signals.

Settings Switch

To change the view of the lock screen there is a settings switch on the top right side of the screen symbol. By clicking on the settings switch you can show and hide the settings.

There will be more settings in near future.


Refresh Lock Devices List

Usually the intervall for showing new locks in reach or hiding locks out of reach is 20 seconds. So the app is refreshing the lock devices list every 20 seconds. The app is scanning via bluetooth for all locks in reach for 6 seconds. When scanning the refresh symbol at the end of the lock devices list is spinning.

You can also start the scan for locks in reach manually by clicking on the refresh symbol at end of the lock list.

To show the menu bar, click on the menu symbol on the upper left side of the screen. There you can switch between the screens of the app and sign out. To close the menu bar just click at the area outside the menu bar.

The term “Keys” within the okey smartphone app means access rights of a user to a lock device. A user can have a direct access right to a lock or indirect access rights e. g., via being part of a user group. Within this menu, all keys (access rights) are listed. Regardless if the access right was granted directly or via user groups. On the left side you can see the lock device name and the ID of the lock device. On the right side there is the expiration date of the access right.

Data Protection, Data Security

User data and lock device data is stored or shown in 3 different places:

The synchronization of lock data to the Secure Cloud Core backend via the okey smartphone app is end to end encrypted and the transfer needs to be authenticated.

Within the okey smartphone app, the provider id, username and password of last login is stored encrypted on your device. Depending on your provider configuration access rights to lock devices may be stored locally in the mobile app for a certain configura-ble time.

The Secure Cloud Core backend is hosted inside the EU - currently by Amazon Web Services (AWS) at location Frankfurt am Main. Since it’s configurable: Please ask your local administration about the extent and duration of data storage. Communication between the Secure Cloud Core backend and the Secure Cloud web frontend is also encrypted.
