What is a WiFi smart lock?

A WiFi smart lock is any smart lock that connects to WiFi to empower users to remotely lock and unlock doors and manage access for visitors. Most WiFi smart locks have a built-in WiFi connection, eliminating the need for external hardware like adapters, hubs, and WiFi or wireless bridges.

Many modern buildings now rely on some form of smart door lock rather than traditional locks with keyholes.

Types of buildings that use WiFi smart locks:

  • Apartment buildings
  • Senior homes
  • Student housing
  • Office buildings
  • Single-family homes

A smart lock can make each of these buildings safer and offer overall convenience to residents and property managers.


Types of smart lock connectivity

There’s more than one connection type when it comes to smart locks. Follow along below as we break down the differences.

Types of smart lock connectivity:

  • Bluetooth: Bluetooth smart locks allow entry through a smartphone’s Bluetooth connection when it’s within range of a lock.
  • WiFi: A WiFi smart lock connects directly to WiFi without the assistance of a gateway.
  • Z-Wave: A smart lock that uses a Z-Wave hub to connect to a building’s WiFi.

3 things to know before you buy WiFi locks

We’ve covered the basics of what a WiFi smart lock is — and the different connectivity types. Now, let’s look at some of the most common things buyers should know before they buy.

What to know about WiFi smart locks:

1. Connecting a smart lock to WiFi
2. Connectivity troubleshooting
3. Choosing the best WiFi door lock


1. Connecting a smart lock to WiFi

The biggest question most people have when deciding whether to install a WiFi lock is how does a smart lock connect to WiFi?

Connecting a WiFi door lock isn’t that difficult to figure out and doesn’t take long. All you need is your smartphone, a working WiFi network, and the smart lock manual.

For most WiFi smart door locks, you’ll need to:

  • Turn on the smart lock.
  • Download and open the smart lock’s mobile app on your smartphone.
  • Select the desired lock from within the app and look for a ‘Settings’ section or similar page.
  • Follow the prompts to connect the lock to WiFi (you’ll likely need to enter the WiFi network’s password).
  • Test the lock to ensure it’s properly connected.

Carefully read the instruction manual for your new WiFi lock to identify the list of instructions specific to your model.


2. Connectivity troubleshooting

Another concern you may have is what happens to a smart lock when the WiFi goes out.

Batteries power most smart locks. This means that in the case of a power outage or internet disconnection, the lock will continue to work. In most cases, users can still unlock the door by entering a PIN code, scanning their fingerprint, or using a physical key, depending on the smart lock model.

However, even though the lock will continue to work, remote and smartphone use will be restricted until the network is restored.


3. Choosing the best WiFi door lock

There are many smart locks on the market, but you’re not looking for just any lock. You want to know what is the best WiFi door lock for your needs. Below are a few things to look for that will help you make your final decision.

What to look for in a WiFi smart lock:

  • Integration capabilities: With smart door locks, you’ll enhance the user experience by integrating with other proptech systems. This means you could potentially integrate your smart lock with a video intercom or other access control system — which enhances accessibility throughout your building.
  • Remote access: When shopping around, make sure the smart lock you want to purchase enables remote access. This means that access can be controlled by one’s smartphone without being present.
  • Battery life: One of the most important factors when looking for a WiFi door lock is battery life. You should shop for the best smart locks with the longest battery life. Plus, some even come with rechargeable batteries.
