Listings commonly support multiple entry methods: fingerprint biometrics, PIN/password codes, mechanical key access, Bluetooth or app-based unlocking, RFID/fob/card access, and web/app eKey sharing.

Most entries are battery powered. One listing specifies 4 AA alkaline batteries (required, not included), and several product bullets list the power source simply as “Battery.”

Auto-lock functionality is common. Examples include a 10–30 second auto-lock on one model and a configurable auto-lock delay ranging from 5 to 900 seconds on another.

Some listings include certifications and standards such as CE, RoHS, FCC, and professional BHMA/ANSI Grade 3 in their product details.

Some listings explicitly list IP ratings (for example, IP65 or IP55). Other results do not clearly specify an IP or weatherproof rating in the available details.

Results include a specified door thickness range of 1.378" to 1.969". Other listings note compatibility with standard left- and right-hand doors, fitting most US standard doors, installation on standard deadbolts, and simple installation often achievable with just a screwdriver (installation times around 15 minutes are mentioned).

Reported details include unlocking speeds around 0.3 seconds up to about 1 second, a 99.99% recognition rate claimed in one listing, and mentions of AI or self-learning fingerprint algorithms that adapt to different conditions.
