Sesame: the smart lock that lets you in when you knock

Smart locks are a burgeoning category, but they all do pretty much the same thing. Sesame has a unique feature, however – it unlocks when it hears the special knock.

It connects to your phone over Bluetooth. You can unlock it using the app, or set a special knock and rap it out on the door. If you want to go easier on your knuckles, you can do the knock on your phone while it’s in your pocket.

You can install it in seconds without any tools – just pop it over your existing lock and tape it in place. Using the app you can let in guests without them doing anything. Only want to let them in during the day? You can control who comes in and when.

Naturally the Bluetooth range is a bit limited, but if you spend a bit more you can get the Wi-Fi accessory that gives you access from a distance.

It lasts 500 days on the supplied lithium batteries and will send you a notification when it’s low on juice.

It’s cheaper than most of its rivals too. It can be yours for $89 (£57), though the standard retail price will be $149 (£96).

Most people will need a lot of convincing before they opt for a smart lock. This one looks simpler than most, and the knock feature – if it works – could be a real USP. It will ship in May, so we should know then whether it has the key to making smart locks mainstream.
