What to know before buying a smart lock

Before buying a smart lock system for your building, it’s important to factor in everything, such as resident needs and building compatibility.

Other considerations before you buy include:

  • Type of lock. There are several types of smart locks, including keypads, key-card enabled, biometric, and keyless door locks. The question is whether one of these will benefit your building the best. For instance, keyless smart locks may eliminate the need to create credentials such as those for key-card-enabled locks.
  • Features. Do you want a basic lock that merely grants access to the front door? Or do you want smart door locks that enable remote access, mobile app use, and an online dashboard?
  • Price. The overall price of a smart lock will differ depending on the brand and its features and capabilities. You’ll also have to consider that the more features you have the more extra costs you might incur — including software and installation costs.
  • Capabilities. Unlike features, capabilities are the special functions your smart lock will bring to the table. For example, you might want to consider a smart lock that has integration capabilities. With integration abilities, you can use your lock with other property tech, such as access control systems and smart home tech.


Integrating your smart lock with other property technology

While a WiFi smart lock is a great device on its own, integrating this technology with a more widespread access control system will give you even more control of your building’s functions.

Furthermore, a fully integrated system with end-to-end connection will empower residents to go keyless. This is made possible when a WiFi lock is integrated with a video intercom, keypad devices, and other solutions.

For example, ButterflyMX access control products integrate with more than 80 smart locks for doors, including Yale, Schlage, and August. This empowers residents to access the front entrance, amenity spaces, garages, elevators, and even their apartment units from just one 5-star mobile app! Further, they can even reserve amenity spaces for themselves and their guests with the amenity reservation software.

Smart lock system FAQs

In this section, we answer the most pressing questions from users about smart lock systems:


What is a smart lock system?

A smart lock system is a door lock device that allows owners, property managers, and residents to access their homes without a traditional key.

These systems use a WiFi connection to enable remote access via mobile apps, key fobs, and sometimes keypads.


Is it worth getting a smart lock?

Smart locks offer residents and managers convenience and safety in the form, even more so when integrated with other security systems like video intercoms.

Residents can easily grant entry to their visitors, and property managers can monitor access events in real-time — as well as keep time-stamped audits.


Is a smart lock safer than a deadbolt?

Smart locks are safer than deadbolts because they use encryption and authentication, and rely on unique credential systems.


Are smart locks easier to break into?

No. Smart locks are designed to withstand attempts of breaking in and other malicious methods, such as lockpicking and bumping. In many cases, smart locks are built to be tamperproof or resistant, reducing the chances of being broken into.

However, some smart locks are still susceptible to failure under certain circumstances. So, make sure to research thoroughly before investing in smart lock systems.


Can smart locks be picked?

It depends on the smart lock. Many smart locks are designed in a way where picking is impossible, whereas others are much more difficult. Ultimately, whether a lock can be picked or not comes down to the smart lock you choose.


Do smart locks work without WiFi?

Some smart locks can work without WiFi, but their functionality is severely limited. For example, your smart lock won’t unlock or lock remotely without a WiFi connection.


Can you still use a key with a smart lock?

It depends on the smart lock. Many smart lock models support traditional metal keys, but not all. If you want to continue using keys, look for a model that supports them alongside other types of credentials.


How do smart locks get power?

Most smart locks are powered by batteries. These locks often include rechargeable batteries, which need charging every few weeks or months. On the other hand, some use disposable batteries. In some cases, smart locks are wired, but they are less popular because installing them is more difficult.
