My Favorite Amazon Deal of the Day: Eufy Security Smart Lock C220

Smart locks are great for many reasons, like not having to worry about giving keys to everyone to who you want to give access into your home, or just swiping your finger if your arms are full carrying groceries. The Eufy Security Smart Lock C220 can do those things and much more, and for a limited time, you can get it for $109.99 (originally $149.99) after using the on-page $40 coupon.

The Eufy Security Smart Lock C220 is very easy to install. You just need to take out your existing deadbolt and the latch, then slide the latch it includes and screw in the keypad and back cover. You'll be using six AA batteries that give you about eight months of battery life, according to Eufy. The setup in the app is also very straightforward and quick.

The smart lock lets you open your door with fingerprints (up to two fingers max per person), voice (you'll need a smart speaker), keypad, app, Bluetooth, and keys (it includes a set of keys). You can assign people permanent or temporary codes to access the home, which is great for family members who visit frequently or for guests if you run an Airbnb. You can also open and close the lock remotely using the app without the need to buy or subscribe to anything that isn't already included in the box.

The Eufy app is smooth and has many options that you can customize in the settings. I really like that it is one of the few companies that don't require you to sign up for a subscription with a monthly fee or buy extra gadgets to unlock features. There is no need to buy a bridge to use the smart lock, as it only needs a wifi connection to work.
