Eufy Security Smart Lock S230 – Keyless Fingerprint Entry

One Touch, 0.3 Seconds — Keyless Entry Built to Last 30 Years

The eufy Security Smart Lock S230 reads your fingerprint in 0.3 seconds and has the door open in about one second flat. Built-in Wi-Fi means you control and monitor it from anywhere through the eufy Security app with no extra hub or bridge — get real-time notifications, unlock remotely for family or guests, and check whether you remembered to lock up, all from your phone.

Four unlock methods cover every scenario: fingerprint, app, keypad code, or the traditional physical key. A built-in sensor detects when the door closes and auto-locks it behind you, and Alexa or Google Assistant handle hands-free voice control. Fingerprint data is encrypted and stored locally on the lock, never in the cloud.

The zinc alloy and stainless steel body is BHMA certified and tested to 250,000 lock/unlock cycles — over 30 years of daily use — while the IP65 rating shrugs off rain, snow, and temperature extremes. The 10,000mAh rechargeable battery runs up to a full year per charge, with an emergency top-up option via any portable power bank. Installation is a 10-minute DIY job with just a screwdriver.
