Smart digital lock cylinder with Bluetooth connectivity and app control, offering keyless entry and enhanced security for your door. The AVATTO SDL-V1-S80 combines a robust aluminum alloy construction with an adjustable 80mm cylinder length, fitting most European standard doors. Unlock via the Tuya Smart or Smart Life app, a mechanical key, or a password—all without replacing your entire lock. The anti-peep password feature ensures privacy, while temporary passwords allow convenient guest access. Powered by 3 AAA batteries, it delivers up to 12 months of typical use, with a USB-C emergency power port for peace of mind. Whether for home, office, or rental properties, this digital cylinder provides a smart upgrade to traditional locking.

Advantages

Upgrade your door security without changing the entire lock. The AVATTO SDL-V1-S80 digital lock cylinder installs easily into existing Euro profile locks, adding smart features like app control, password entry, and event logs. Its aluminum alloy body resists wear and corrosion, while the adjustable cylinder length (40-100 mm door thickness) ensures a perfect fit. The anti-peep password function lets you enter a random string of digits before or after your real code, preventing shoulder surfing. Temporary passwords can be created for visitors or service personnel, with time-limited access. All unlocking events are recorded in the app, giving you a complete activity history. With Bluetooth connectivity, you can manage the lock from your smartphone without needing a separate hub.
