Leave your keys at the door with these Smart Door Locks
Forget the humble key and discover smart door locks, which can be opened with keycodes, fingerprints, smartphones and more.
Since the beginning of time, humans have had possessions. The only difference is that 2.6 million years ago it was stone tools and today it’s designer clothes, furniture and smart gadgets. Nevertheless, the safety of these possessions has always been important…
In the earliest days, a simple crevice in a cave or a hole in the ground would do the trick for storing animal bones and sharp stones, whereas nowadays the increased value of “stuff” requires something a little more advanced: door locks.
The earliest door lock on record consisted of a wooden crossbar on two wooden brackets mounted on the door and its frame. The next stage in development was the use of a key, which the Egyptians invented some 6,000 years ago.
Known as a wooden pin lock, it was an early predecessor of the pin-tumbler, where pins within the lock are lifted out of holes using a key to allow the lock to move and open. When the key was inserted, pins within the fixture were lifted out of drilled holes within the bolt, allowing it to move.
Locks such as these evolved as a practical solution to the problem of how to open a barred door from the outside, pointing to an invaluable measure of privacy and the securing of personal space. Homes, public toilets, changing rooms: these are all places that would cease to function if their inhabitants or users weren’t comforted by the security of a door lock.
Over time, door locks have advanced to become more complicated as a way of keeping people out. An attempt to remove keys from the equation has seen the invention of push-button locks whilst smart home systems and IoT technology has made digital and smart locks a viable option.
A smart lock lets you create virtual keys and time-sensitive passcodes, so you control who can get into your house, and when. It can also alert you whenever a door is locked and unlocked, using fingerprint sensors to tell parents if their children arrived home on time. They can also lock themselves if you forget to do it yourself.
Smart locks might seem like something straight out of a science fiction movie but they are real and surprisingly convenient. Here is a selection of some of the best available right now.
Bosma Aegis Smart Door Lock
The Aegis Bosma Smart Door Lock turns any deadbolt lock into a smart lock by simply replacing the indoor portion of the existing deadbolt. It uses a 6-axis sensor to detect whether a door is fully closed or left slightly open. The advanced door lock then sends a notification to let you know.
When opening the door, the Aegis smart door lock uses two methods – fingerprint or facial recognition and powers a Bank-Grade AES-128bit Advanced encryption to provide flawless security. Other features include an accompanying app and Alexa/Google Home compatibility for a total smart home experience.

August Smart Lock Pro
The August Smart Lock Pro also connects to a front door deadbolt, allowing you to use your keys while also taking advantage of smart home features without replacing the entire hardware set. An app similarly lets you control the door lock remotely, granting guest access, and seeing who got home and when.
The smart lock is packed with security features. It requires two-factor authentication, offering a solid barrier of protection against hacking and a lost-phone feature can disable the August app remotely so no one can access it.

Qrio Smart Lock
Designed, developed and manufactured by Sony, Qrio Smart Lock is a smart lock that uses a smartphone as a key. On the outside, a minimal design and neutral colour encases the very best encryption technology Sony has to offer.

It can be installed without removing the existing door lock and works on numerous types of thumb turn locks by using an adjustable bolt turner to fill any potential gaps.

Netatmo Smart Door Lock
Another great option for those who favour tradition over futuristic front doors is the Netatmo Smart Door Lock. Compatible with Apple’s HomeKit standard, it ships with three physical keys that use NFC to instantly and securely unlock the door mechanism when inserted into the lock.
Once the key is inserted, the mechanism works like a regular key and must be manually rotated to release the deadbolt. There’s no hands-free or remote lock / unlock option, which might be a deal-breaker for many but there is still the option of unlocking the door with the Netatmo Security app.

The Handle Smart Lock Concept
Imagining the next generation of smart door locks, Chinese designers Wayne Lu and Wenjie Zheng have created The Handle concept. It combines a pin code with fingerprint access and a traditional door handle, which renders the technology invisible. The fingerprint recognition, for example, is integrated into the reverse of the door handle.
Touch Smart Lock Concept
Industrial designer Kaiwen Li has achieved a similar outcome with her smart door lock design. Called Touch, it also uses a touchpad for pin code-access and what looks like a fingerprint recognition feature on the door handle. Similar to The Handle, it packs all of this inside a sleek and slimline design imagining a discrete smart door lock in the future.
