Smart lock learns your fingerprint

The eufy Smart Lock C220 gives you flexible control of your door lock. The free eufy Security app lets you configure a host of useful settings to make your home secure, yet accessible. Built-in Wi-Fi and Bluetooth mean you can control the lock from practically anywhere, whether you're inside your home or vacationing in another country. It also has AI that learns your fingerprint more precisely with each use. You can even unlock and lock it using your Apple Watch (sold separately).

Give permanent or temporary numeric passcodes to up to 100 users. Track lock activity and see the current status. Set the door to auto-lock when it's closed. Protect numeric passcodes from being read by onlookers, and lock out any unauthorized person attempting to guess their way in.

Secure options and long-lasting battery power

Giving users unique passcodes — or using their fingerprints — lets you track who comes and goes, and when. You can even set a window of time for a certain user's access to be available — for example, a trusted babysitter or repair person.

This lock uses 8 AA batteries, which will power its operation for up to eight months. In a pinch, you can use a portable battery charger to power up the lock via the micro-USB charging port on the bottom of the exterior of the lock, or just use one of the included physical keys — it comes with two.

Simple, private control

The user-friendly eufy Security app makes setup and configuration-tweaking easier, and it also works with Google Assistant or Amazon Alexa (devices sold separately). And eufy doesn't store your information in the cloud — everything is saved privately and securely on the device.
