What is a smart lock? Surprisingly, trade associations like the Associated Locksmiths of America, Society of Professional Locksmiths and Institutional Locksmiths’ Association don’t offer a definition.
For decades, fast-food restaurants and hotels have used numeric keypad locks and electronic deadbolts, but these “keyless locks” use magnets and radio-frequency identification, not a network connection.
“Electronic locks cannot be integrated with smart home systems in the same way that smart locks can, nor can they be controlled via a smartphone over a wireless network,” says Lock Blog’s Hugo Reed.
Unfortunately, smart locks don’t have a lot in common. Some use WiFi, others use Bluetooth. Some connect to an existing deadbolt and others replace it altogether. Thankfully, even inexpensive smart locks support features like temporary access codes and a keyed-entry failsafe (which is a must have).
Are Smart Locks Safe?
All locks are vulnerable to hardware risks and no type of lock is 100% safe or effective. However, internet-connected locks are also vulnerable to software and power risks:
Firmware updates — Hundreds of Airbnb guests were locked out of their rentals when a software update caused a “fatal error” in some LockState 6i/6000i smart locks. The $469 lock couldn’t be fixed remotely, so homeowners had to send their locks back to the manufacturer to be fixed or replaced.
Hacking — “Many of the manufacturing companies don’t allocate resources and funds to securing their devices, because as some will honestly admit, ‘Consumers don’t pay for security. They pay for functionality,’” explained cybersecurity-expert Bruce Schneier in a TechTalks’ interview.
Privacy and data collection — Some smart home control apps require unnecessary permissions, like access to photos, videos and address books. On top of that, overseas developers are sometimes outside the enforcement of American and European data-and-privacy laws.
Power failure — Smart locks requires batteries, and those batteries only last 6 to 12 months before they must be replaced. Similarly, a smartphone with a dead battery can’t communicate with a smart lock.
Hardware vulnerabilities — Few (if any) smart locks meet the highest security standards for door locks: ANSI/BHMA Grade 1 certification and UL437 (lock picking test) compliance.
Despite these shortcomings, smart locks are here to stay. The ETSI Technical Committee on Cybersecurity recently announced ETSI TS 103 645: a “standard for cybersecurity in the Internet of Things.” This proposal lays the groundwork for a software certification program to complement the hardware standards enforced by Underwriters Laboratories, the America National Standards Institute and the Builders Hardware Manufacturers Association.
The most convenient smart locks are designed to work with home automation systems like Alexa, HomeKit, Google Home, or specific products like Nest (WiFi thermostats) and Ring (video doorbells). That said, always check compatibility before buying: Some smart lock accessories are just as expensive at the locks themselves.
How Much Does a Good Smart Lock Cost?
A good smart lock (with verified, above-average reviews) costs approximately $167, according to a 12-month analysis of price trends. Those same keyless entry locks cost around $122 while on sale: an average discount of 27%. For those who want keyless entry and nothing more, “dumb” electronic deadbolts (like models from Schlage or Kwikset) typically sell for much less. Here are the best affordable smart locks:
Methodology for Selecting Products
I use data science to discover above-average products that are selling for below-average prices. To find smart locks with below-average prices, I first assemble a list of candidates, then organize those products by their 12-month average sale price, determine the median value and then exclude any lock with a price above the mid-point.
To find WiFi locks with above-average reviews, I measure the relationship between 1, 2, 3, 4 and 5 star ratings and flag outliers that fall outside of a normal statistical distribution. I also discount paid, sponsored and unverified reviews as well as unhelpful review behaviors from verified customers. Models with an average adjusted rating of less than 3.9 out of 5 are excluded; in the end, fewer than 15% of the analyzed products remain.
