How Does a Smart Door Lock Work?

Most smart locks require a physical installation of a new, battery powered lock on your door, but certain models can simply be fixed over your existing lock.

Once the smart lock is in place, it can be activated (unlocked or locked) from a distance via an app, or with a simple swipe using a special access card or fob in front of the lock itself — ideal for when you’re overloaded with shopping bags and don’t want to fiddle about with keys.

The most high tech smart locks feature touchscreens with pin codes for entry or even fingerprint scanners.

Smart Lock Features

Operated via a simple Smart phone app, Smart locks use a Bluetooth, Z-Wave or Wi-Fi connection to control the locks in your home from a distance as long as you have access to an internet connection.

That means that you can lock or unlock your door from a distance to allow people access, or when you are at home and you are already snug in bed you can check via your phone that everything is locked up tight without having to get out from under the covers.

It’s worth noting that Bluetooth connections only works within a smaller area, whereas a Wi-Fi connection can be used at any range as long as you have a Wi-Fi connection.

However, Bluetooth uses less battery power than Wi-Fi, so your Smart lock won’t run down so quickly.

Z-Wave connections require a hub in order to function if you’re going to be operating the lock using a Smartphone, and has a range of about 120 feet.

The best smart locks incorporate security cameras so you can see who is approaching your property and choose whether or not to give them access without having to open the door manually.

Many smart locks send alerts and create activity reports to keep you informed as to who is entering or leaving your home, and at what times.

Some smart door locks do away with the need for traditional keys completely, whereas others keep the option to be manually locked or unlocked using a key if needed.

Will a Smart Lock Work For Me?

The type of door you have will determine whether or not a smart lock will work effectively.

If your door is difficult to lock or unlock — for example if it needs to be pushed shut or pulled open at the moment of locking to engage the bolt — a smart lock may not function properly.

Similarly, if your existing lock mechanism is stiff and difficult to turn, or if the bolt doesn’t extend fully into the doorjamb you may encounter issues when trying to use a smart lock.
