Digital lock cylinder Avatto SDL-V1-B100, 100 mm, black

Avatto SDL-V1-B100 is a 100 mm digital lock cylinder designed for EURO profile doors with thickness of 38–50 mm. The cylinder combines a fingerprint reader, keypad and mechanical key access in a single rotating head and fits standard European locks without replacing the entire door cassette. It is suitable for residential and office doors and is made from durable materials for everyday use.

Advantages

The lock supports five unlocking methods — fingerprint, PIN code, proximity card, mechanical key and the TUYA smartphone app — allowing flexible access control for different users. Installation is simple and fast: replace the old cylinder with the new one using basic tools and adjust the internal knob to fit door thickness. The device consumes little power and uses three AAA batteries, while emergency charging is available via USB or with the included mechanical key.
