Customer feedback praises the lock's appearance, features, keyless entry options and app control, but also describes mixed experiences with fingerprint recognition, ease of use, reliability and connectivity. Battery life and durability are notable concerns, including reports of 8 AA batteries lasting 2–3 months and units failing internally. These reports matter for a Wi-Fi lock intended for frequent everyday entry, but do not establish how any individual unit will perform.

Positive themes

Customers praise the appearance and feature set, including keyless entry and app control.

Negative themes

Battery life is criticized, with reports that 8 AA batteries last 2–3 months.
Some customers report internal breakage or loss of Wi-Fi connection.

Mixed feedback

Feedback on fingerprint recognition, reliability and ease of use varies. Some report reliable fingerprint reading at different angles, while others describe recognition or operation problems.

Frequently asked questions

Can the eufy Security C33 be controlled remotely?

The listing says built-in Wi-Fi supports app control, access management, real-time notifications and event history. Customer feedback also includes reports of lost Wi-Fi connection.

What are the stated door-fit requirements?

The listing specifies a 2 1/8 in bore hole, a 2 3/8 in or 2 3/4 in backset, and door thickness of 1 3/8 in - 2 1/6 in. Confirm the exact product configuration because the listing uses both deadbolt and lever-lock terminology.

The listing says it is not currently compatible with Apple HomeKit, IFTTT or Matter.

How often do the batteries need replacement?

The listing specifies 8 AA batteries but gives no battery-life estimate. Customer feedback includes reports of replacing all 8 every 2–3 months, so actual battery life may vary.
