Connected access means better security and control 

More secure, more convenient and more efficient

How our NB-IoT smartlock system works

Our smartlocks connect to the internet with a new technology called NB-IoT, built specifically for device to cloud communications so that you have the best security for your assets and buildings, and you are always in control of who goes where at what time with live notifications. See how it works below.

How to make a digital key and unlock

Smartlocks include iSIM's + 30MB pre-paid data* & IoT Modules (NB-IoT, LTE-M, LTE, 2G/3G)**


Log into Access Management Software

A user generates a request for a digital key for a specific lock in a booking calendar inside software for any future date and time. 


Request arrives at NB-IoT Cloud Platform

Request arrives at our platform and here it is assigned a unique ID, and stored in the cloud software database.


Digital Key arrives at smartphone app

Unique ID is sent to users app - it appears as an unlock button, and waits to be pressed during selected time period by user


User hits unlock button in smartphone app 

User hits app unlock button which sends unlock command into the platform to check validity/time and if validated the command is routed into the global NB-IoT network


Unlock command arrives at smartlock

Command arrives at the lock SIM, the lock wakes up, and activates the motor to unlock. Message is sent back to database about this unlocking event and forwards notification to account owner.

Aruba Beach Resort Digital Keys App project

Based on the Gold Coast in Australia, Aruba Beach Resort is a 3 star-rated three-storey walk up resort apartment building ideally situated only 200 metres from the beach, Casino and Gold Coast Convention and Exhibition Centre. Resort rooms have fully equipped kitchens and private balconies.

Task - The owners of the Resort had been using metal keys for room access since the resort was built in the early nineties and they had grown sick of paying locksmiths $150 to come out and replace locks atleast once a week from guests who had lost their keys, or forgotten their keys.

Solution Digital Keys built a self check-in app and system which enabled guests to self check-in on their phones and receive a unique time-sensitive code emailed to them to unlock their rooms. The guests were able to change the code to something they could easily remember like their bank PIN code. This way the guests just had to remember their PIN and enter into the numberpad locks on their room doors (and common doors) to let themselves in.  Guests liked the fact that they did not have to carry around metal keys to access their properties.  


Benefit The managers who live on site were happy to be able to sleep fully through the night again as they never had to get up to let in guests who had locked themselves out in the middle of the night. The cost savings from not having to pay locksmiths to come out to replace the locks quickly added up.

Important Information 

*All our NB-IoT smartlocks come fitted with a free iSIM card and 30MB of pre-paid data to connect to the Global IoT Network (NB-IoT, LTE-M)

Our iSIM's work in over 20 countries and last approximately 2-5 years (based on 3-6 activations a day). See available countries on our network coverage map page here.

^^Local NFC unlocking (with NFC compatible phones, cards, rings etc) can be used after programming the smartlocks once for time-sensitive use over NB-IoT network and writing to cards with digital keys app

**NB-IoT smartlocks powered by 4AA standard alkaline batteries (Life approx 2 years with 4-6 activations a day) or use 2 2450mAH lithium thionyl chloride 3.6V batteries to extend life to approx 5 years

From the image above, you can immediately see one of the key benefits NB IoT smart access has over other brands, and that is there is ‘no onsite network infrastructure’.

When smart locks first came onto the market a couple of years ago, they were targeted at homeowners, with benefits marketed such as; Give a digital key to a cleaner which only works from 11am-1pm every Wednesday, and so much more...
