The Best Smart Locks (Under $200) For Sale on Amazon in 2018

Not all smart locks are created equally.

Simple electronic deadbolts let you unlock a door by punching a code (like the "employees only" door at a fast food restaurant). Other locks can electronically sense when a "key" is waved in front of it (like a hotel door).

High-end smart locks are designed to work with home automation systems like Alexa and HomeKit. These locks use WiFi (sometimes adapters are required) to work with video doorbells, home security cameras, etc.

Some locks can issue temporary access codes that eliminate the need for spare keys and others are designed to use your traditional keys as a backup.

Smart locks aren't perfect. They're expensive, they can be hacked and their batteries need to be changed several times per year. If you aren't handy or tech savvy, a true smart lock might not be worth it. You can score a great electronic deadbolt from Schlage or Kwikset for between $50 and $100.

If you're looking for a more advanced smart lock, here are the best-reviewed models selling for less than $200 on Amazon:

This Schlage smart lock installs quickly and is easy to use, according to several happy customers. Some reviewers had trouble resetting the lock's codes or keeping the lock synced with a smart home hub. The lock's battery life has mixed reviews, but this really depends on the quality of the batteries used.
