Secure your assets with  NB-IoT smart padlock

Connected, secure, waterproof padlock with Digital Keys 

Get in control with connected access

5 years battery life

2 x lithium thionyl chloride batteries (2450mAH 3.6V) gives up to 5 years battery life (based on 5 activations/data transfers a day). Lock remains in deep sleep mode and is only awoken for a couple of seconds when commands are sent or data extracted from the lock.

Internet connected

Connects to the internet with NB-IoT, LTE-M (LTE, CAT-M, 2G/3G fallback) which exists on mobile networks. If a connection cannot be established on NB-IoT, or if it doesn't exist yet in your country, the lock is programmed to use LTE or LTE-M which exists on 4G networks

5 year warranty

Comes with a standard 1 year warranty, which can be extended to 5 years for a small fee. With approx 5 years battery life, and 5 years warranty, and a SIM and data connection included (30MB), you NB-IoT smart padlock is good to go out of the box for around 5 years.

Digital Keys unlocking

Use the digital keys app to unlock your smart padlock for any date and time period. You can also unlock without the app with a time-sensitive PIN (account administrator can generate the PIN in access management software and email end-user or tell them the PIN over the phone.

For exterior and indoor use

Stainless steel casing, armoured glass numberpad and tamperproof screws makes it suitable for outdoor and indoor use on cabinets, gates, electric boxes, garage doors, storage boxes etc.

Built in alarms

With built in tampering motion sensors, get text messages if someone attempts to break open the padlock. Unnatural movements or force cause the acoustic alarm to sound.

Live tracking and tracing

Keep posted on everyone's comings and goings with live notifications every time your padlock is unlocked. All activity of locking and unlocking is stored in our access management software

Frequently asked questions about NB-IoT smart padlock

We have our own app and software, do we have to use your app and software?

We have built API's so that you can add all the features of the Digital Keys apps and software to your own apps and software. Visit our API's page to learn more. To get a copy of our API's and to start building your integration email us at

When and where can I buy the NB IoT smart padlocks?

Our NB IoT smart padlocks will soon be available to purchase on our website or at your local distributors or local telco's. Subscribe to our newsletter by sending an email to to get ongoing updates to availability.

Will the NB IoT smart padlocks work in my country?

NB IoT networks have been rolling out in dozens of countries across the planet. Please check our page 'NB IoT Network Map' for country rollout details. Also please send us an email with your country and we will chase up with our telco partners about NB IoT network availability around you.

How strong/heavy duty/rugged is your NB IoT smart padlock?

The padlock casing we use in made of stainless steel with armored glass numberplate (to enable NB IoT signals and commands to penetrate). The casing is from a top selling RFID/GPS padlock (we use our own NB IoT PCB's), that has sold hundreds of thousands over the last few years for use on shipping containers, sheds, trailers etc, so it is heavy duty and can handle almost any conditions thrown at it.

Do you have discounts for bulk volume purchases?

Yes, please email us at to discuss your needs and wants.

How do you get such a long battery life (around 2 years) as compared to only a few months with other connected locks (e.g Wi-Fi/BLE)?

Our locks remain in sleep mode most of the time, conserving battery, and are only woken up for a couple of seconds when you need to use the lock (e.g to unlock it, get live audit). All other connected locks are constantly on and connected to the internet sucking up battery life.

Where does the data lie, and who controls the data of the NB IoT smart padlocks?

Our cloud servers are hosted at Amazon Web Services (AWS) in your local country. No one has access to your data except you. If you want to host the system on your local servers, please get in touch with us to discuss further at

Where is my data held and who controls it?

Your data is safely secured and managed at your telecommunication Company who you sign up with for the connectivity services. All our smart access system services and data rests with the telecommunication companies who follow strict data legislation, standards and policies to ensure the highest levels of data security, privacy and integrity. If you can trust the telecommunication companies with your mobile phones, and mobile data, then you can trust them for NB IoT smart access.

Is there ongoing costs to use the NB-IoT smart padlocks?

Yes, there are connectivity costs to use our NB IoT smart padlocks on local telecommunication companies mobile networks. The locks connect to mobile networks like mobile phones do. But unlike mobile phones, the smart padlocks use very little data - on average less than 5-10 MB a month. For example unlock commands and data retrievals (such as for the live audit) are around 8-10 bytes on average.This means we can take advantage of the lowest data plans offered by local mobile network operators for utilising their NB IoT networks. For example in some European countries you can pay a one-time fee of 10 Euros when you purchase our smart padlock and receive a data flat rate of 500MB to use over 10 years on Deutsche Telekom's NB IoT network - click here to see more. Thats right 10 Euros for 10 years. Prices depend on different carriers in different countries. Please check with your local carrier or our distributors for pricing, or send us an email if you would like to know more.
