Frequently asked questions

Will the Mortise Smartlock work on my door?

Yes - the minimum thickness is 30mm. And it will work on inward or outward swinging doors, and left or right swinging doors. Please tell us your door type when you order.

Can I still use my original key or manually lock/unlock the door

Yes. You can remove the cylinder from your existing lock (most locks) and place it in the NB-IoT mortise smartlock, so you can still use your existing key. Alternatively you can use the new keys included in the box.

Will the NB IoT mortise smartlock work in my country (is the network on)?

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 if its not on this list, and we will chase up with our telco partners about NB IoT network availability around you.

Do I have to change my locks to install NB-IoT Mortise Smartock/How to install?

Yes, the instructions for installation are below - and are also in the Manual - found at the top of this page under the images of the smartlock.

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 smartlocks?

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 or at Amazon Web 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.

What if my phone runs out of batteries, can I still unlock?

You can always still use your metal key to open the door. Alternatively, you can also use a friend or neighbor’s phone to download the app, use your login to the app to unlock your door, and then delete the app. You can also use the provided keycards, fobs, stickers and rings to unlock, which are programmed to work permanently and you can also program them for time-sensitive use. If you want to make time limited keycards/key tokens, you can use the Digital Keys app which is available to download in the online stores.

What if the power goes out?

The NB-IoT Mortise smartlock runs on 4AA batteries, it does not require mains power. So if the power goes out, you can still use your smartlocks as normal.

What if the NB-IoT mortise smartlock runs out of batteries?

Battery life is about 2 years (around 5 unlocks/activations a day). It will keep notifying you through app when batteries are low. If the batteries run out, you can still use metal keys to unlock your door (perhaps use your current method of having a spare key with a family or trusted friend.

How many Digital Keys can I make and send to others?

There are no limits to the amount of digital keys you can generate and share with others. You are in control of who you want to “authorize” and for how long/specific dates and times/regular dates and times. You can also cancel the digital keys at anytime in seconds in the apps and software

How many Narrowband Smartlocks can I manage/control simultaneously?

You can manage as many Narrowband smartlocks as possible on just the one account. This makes it easy to manage multiple properties and multiple doors. Such as in offices or for managing lots of rental properties. You can connect new locks to your account at anytime too - you can try one door, and add more later if you like. You can group doors on one site, in one app, and even find sites on maps (for PC based software account). There is no setup involved by you. We connect to your account when we ship.

What is the warranty and return policy?

We guarantee that Narrowband Smartlock will work for your door if your lock is a single cylinder separate deadbolt. We refund you 100% in case of product defect or incompatibility - we don't think it will happen though :) The product also comes with a 2-year warranty.

How secure is NB-IoT Mortise smartlock? Can it be hacked?

All other technologies used in smartlocks have been hacked but not the technology we use – which is NB IoT. This technology has been built specifically for use in smart devices, and has many levels of security features and encryptions throughout.

Can I use NB-IoT Mortise smartlock on common doors, such as the front door to an apartment building?

Yes – the common door can be programmed to accept the same digital keys of the users of your other door.

Is NB-IoT Mortise Smartlock waterproof?

Yes, the lock is waterproof and can be used indoors or outdoors.

Where can I learn more about Narrowband IoT network?

You can learn more about NarrowBand IoT at the GSM website here

Is there a developer API? Can NB-IoT Mortise Smartlock be connected to other smart devices?

Yes! We have an API that is available for developers to build their own integrations to their own products/services (for example if you have your own facilities management software and/or your own smartphone apps, you can add the features of the digital keys apps and access management software to your own software/apps. For companies looking to integrate their buildings with NB-IoT Mortise Smartlock, our developers can support you, please email us for more information.

What are the smartphone requirements and other requirements for NB-IoT Mortise smartlock?

To use the ‘write to token (keycard, fob, sticker and ring)’ feature, you will need an Android phone with Host Card Emulation (HCE). To see a list of HCE Android phones go to All our supplied tokens come with unlimited use so you can use your tokens immediately. You will only need the Android HCE phones if you intend to make tokens time-sensitive and on a regular basis (such as in a hotel use). We will ensure NB IoT is switched on and working well near your address. Simply download our app in the online App store (iPhone) and the Google Play store (Android) and you can start using all the features of NB-IoT Mortise Smartlock.

What batteries does NB-IoT Mortise Smartlock use?

4 standard AA batteries. You can get the standard batteries in any supermarket.

Is Narrowband Smartlock compatible with Apple Homekit?

No. The concept of Narrowband Smartlock is not to use Wi-Fi or be compatible with hubs or kits that rely on Wi-Fi, as Wi-Fi is expensive, unreliable, has blackspots and requires onsite network infrastructure and equipment.
