Ways to unlock




After you have generated a digital key in the Digital Keys Management Software, or made a request for a digital key in the digital keys app (see here for how to do this), your digital key will download into the digital keys app in the form of an unlock button, corresponding to the room number/lock number that was booked. All you have to do to unlock the door is hit the unlock button on the app, and then touch the NB IoT logo on the lock (on the NB IoT smart lock LDK400) or touch the star * on the lock numberpad (LDK100). It should take 1-3 seconds to unlock. Depending on network load, very rarely it may take up to ten seconds to unlock. 

STEP 1  - Open Digital Keys app and hit 'unlock' button.

STEP 2 - Touch star button on numberpad (LDK100 on left) or touch NB IoT logo (LDK400) right (this wakes up the lock/helps conserve battery)

STEP 3 - Enter!


NB IoT Smart Lock LDK100 (with numberpad) comes with a 4 digit PIN. The PIN can be changed anytime to a PIN of your choice in the digital keys management software (see how here).


All our NB IoT smart locks comes with 2 NFC master keycards. You can make these keycards or any time-sensitive keycards or NFC tokens with our Digital Keys app for Android phones.


For more regular users, or where there is high traffic we encourage local NFC unloking with Android phones. Simply hit the unlock button in the digital keys app, and then follow the steps of touching the lock to unlock it (as outlined above)


All our NB IoT smart locks come with 2 mechanical metal keys.

Digital Keys Universal App (Android and iPhone)



Download the Digital Keys Universal App from the online stores, and sign-in or sign-up. If you are administrator/account manager please use the same email and password you used for signing in to the Digital Keys Management Software.


Upon signing in (only need to do this once, or after a new digital key is generated for you), your list of digital keys which has been created for you by your account administrator will appear. Touch the 'unlock button' for the door you want to unlock.

Wait 1-3 seconds for unlock command to go over NB IoT network/query device status

After 1-3 seconds a message will appear saying, 'Done touch the NB IoT logo to open it'. You're door will be unlocked and you can enter.


You can request at anytime a digital key from inside the digital keys app. Upon making a request for a digital key, after choosing date/time and lock, your account administrator will receive an email asking to approve your request. The account administrator can approve the request simply by hitting an approve button inside their email. The idea of this function is to make management of the locks and system the most efficient it can be, so the account administrator does not have to worry about logging into the software and generating new digital keys each time for authorised users. The end-user can 'generate the digital key' themselves inside the app and all they have to do to get access to a lock is to seek the approval of the account adminstrator, by getting them to hit one button inside their email.

1. To make a request for a digital key, firstly select 'Request a Digital Key' from the menu bar - as shown below.

2. Select the date and time for the digital key to work (select outer circle on the clock face first for times between 12AM-11:59AM. Choose the inner circle on the lock face for times between midday and midnight.

3. Choose from the list the locks/access points which you want a digital key for. This list will be made available for you to choose from when your account administrator first sets you up as a regular user in the digital keys management software account. If the lock you want access to is not on the list, then please follow up with your account administrator.

4. Review your Digital Key request, and if you like, give a message to your account administrator stating why you need the digital key for the date/time you have requested. For example you could say, "I'm opening the shop tomorrow as John is on leave, and so I need the digital key, or "I need to get to the server room tomorrow between 2-3pm to upload some updates of the software", or whatever reason it is you need to get a digital key. After you hit the 'Submit your request' button, your account administrator will immediately receive an email, and if they approve by hitting the one button in the email, then your digital key will appear within a few seconds. You will need to refresh the screen if you have the app open to see your new digital key(s).


If you would like to use your NB IoT smart access control solution just like a typical keycard system, such as those commonly used in hotels and offices, then follow the steps below to make a NFC card/token work for a specific lock/room for a specific time period for a specific person. 

1. Generate the digital key in the digital keys management software (as outlined above) or make a digital keys request in the app (see section above). 

2. Select the NFC card maker menu item.

3. Place one of our supplied NFC card/tokens* to the back of the phone (Android phone operating system version 5.0 and above) and hit the 'Make Card' button. The digital key will then copy to the card/token, and you are ready to use the card/key for the time/date/lock you are authorised to access.
