Front-door deadbolt with built-in Wi-Fi

The eufy Security Smart Lock C220 replaces a standard US or Canadian deadbolt and adds fingerprint, keypad, app, Apple Watch, physical key and voice control through Alexa or Google Assistant. No separate bridge is required because Wi-Fi is integrated. Installation takes roughly 15 minutes without drilling.

Eight-month battery span and IP53 rating

Eight AA cells power the lock for about eight months, though actual life varies with how often the door is locked and unlocked. The IP53 rating means the exterior assembly resists dust and spraying water, so it handles normal front-door exposure. BHMA Grade 3 certification confirms baseline residential durability.

Self-learning fingerprint sensor

The fingerprint reader improves recognition with every use, unlocking in under 1.5 seconds once enrolled. Buyers who want a second lock on a different door or who need a mortise or rim cylinder instead of a deadbolt will need a different product. The lock also joins eufy doorbell routines inside the same app for coordinated keyless entry.

Questions about this item

Will the C220 fit the standard US deadbolt already on my door?

The lock is compatible with most standard US and CA deadbolts and installs in roughly 15 minutes without drilling.

How can I confirm the fingerprint sensor is working correctly after installation?

Unlock with a registered finger; the sensor should release the bolt in under 1.5 seconds and recognition improves with each use.

Does the package include batteries and a physical key, or must I buy them separately?

The lock runs on 8 AA batteries for around 8 months of use and a physical key is one of the six unlock methods, so both are required for operation.
