eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock

The C220 replaces an existing deadbolt; eufy says it fits most standard US and Canadian deadbolts and goes on in about 15 minutes without drilling. It unlocks six ways: fingerprint, keypad, the eufy Security app, a physical key, an Apple Watch, or Alexa and Google Assistant. Wi-Fi is built in, so there is no bridge to plug in, and the app keeps an event history and sends alerts.

The C210 below it has the keypad and Wi-Fi but no fingerprint reader. If you already have a eufy doorbell, the lock joins the same app.

Worth knowing It runs on 8 AA batteries, which eufy says last around eight months depending on use. It is BHMA Grade 3, the basic residential grade.
