eufy Security Smart Lock C220 with Square Door Handle: features and specs

The eufy Security Smart Lock C220 is a fingerprint-enabled smart deadbolt with built-in Wi-Fi. This listing is a pack that includes a square door handle alongside the lock, so it covers both the deadbolt and the handle on a front door. The listing gives few details about the handle itself, so check the exact contents before you order.

Six ways to unlock

eufy says the C220 can be opened in six ways: by fingerprint (in under 1.5 seconds, according to the brand), through the eufy Security app, with the keypad, with the physical key, from an Apple Watch, or by voice with Alexa or Google Voice Assistant. A mix of methods means a family member without a phone can still use the fingerprint reader or keypad, and the key remains as a backup.

Self-learning fingerprint recognition

Fingerprint locks can fail when a finger is damp, dirty or placed at an odd angle. eufy describes self-learning AI that is meant to become more precise with each touch, so repeated attempts are needed less often. Results vary from person to person, and most fingerprint readers work best when a finger is clean and dry.

Battery life

The lock uses eight AA batteries, and eufy says they last around eight months. The brand adds that this varies with how often the lock is used. Putting a reminder in the calendar to check the battery level in the app is a sensible habit with any battery-powered lock.

Built-in Wi-Fi, no bridge

No separate hub is required. The eufy Security app provides remote control, access management, real-time notifications and an event history. If you have a eufy doorbell, the lock can join routines in the same app.

Installation and compatibility

The listing says the lock suits most standard US and Canadian deadbolts and installs in about 15 minutes without drilling. Because it replaces existing hardware, check door thickness and bore size in the manual. Because this pack includes a handle, also check that the handle's size and position suit your door. Follow the manual and any local rules.

Weather and durability

The listing gives an operating temperature range of -22°F to 158°F (-30°C to 70°C) and an IP53 protection class. IP53 generally means protection against limited dust and against water spray, not immersion, so it is built for a covered or exposed door but not for submersion. The lock can send an alarm if it detects an unusual attempt to open it. eufy offers an 18-month warranty with support by phone, email and live chat.

Who it suits

It suits households who want keyless entry and fingerprint access, including for children or visitors who may lose a key, and cold-climate users who need a wide temperature range.

• Door preparation: check your deadbolt is a standard US or Canadian type.
