Have you ever fumbled through your bag in the rain, trying to find your keys? Ever leave them at the office? A smart lock is a solution to all that. Just type in a keypad code on the smart lock or unlock the door via a smartphone app. It’s easy.

A smart lock can also grant limited access to your home to a plant-sitter or dog walker without handing over a physical copy of your keys. And thanks to time limits and other fine-tuned controls, you can ensure that permission expires and that way those same guests won’t be able to get back inside your home without your permission later down the road.

There are many different smart locks by a variety of reputable brands like August, Schlage, Yale and Kwikset. And while they look different, and have different features and price points, virtually all smart locks work the same way: with the help of a battery, and a wireless connection, they lock and unlock. Bluetooth connections let you control your lock from short range (30 feet or so) and Wi-Fi lets you control it from anywhere through the internet and attach to virtual assistants at the cost of putting your lock on the broader internet.

A smart lock will take a little more installation than a plug-and-play smart lightbulb or speaker, so pull out the toolbox and make sure your lock of choice works with your virtual assistant of preference.But are smart locks safe? The answer is “at least roughly as safe as a traditional lock.” As with any smart device, especially one that connects to the internet, it can be hacked, and as such you should buy from a reputable brand and keep your eye out for news about exploits that might require an update.

But ultimately no lock, smart or otherwise, can keep out someone who is truly determined to get into your house. Hackers are a threat, but so is anyone with a crowbar or set of lock picks.
