SIRO Smart chain lock SL03411B

A lock without a key? This is possible with the SIRO Smart chain lock, because instead of a conventional key, the lock is unlocked with a stored fingerprint or with the “Smart Life” app on a smartphone. The waterproof lock made of stainless steel mesh with protection class IP65 is particularly suitable for protecting bicycles and outdoor furniture from theft.

Your finger is the key

The smart lock is not only ideal for bicycles or outdoor furniture, the possible uses of the chain lock are versatile and particularly useful for all items that you want to protect against theft quickly, safely and easily. The lock can be easily unlocked with a fingerprint – never again wasting time looking for the key.

After a super simple setup with the “Smart Life” app, the lock saves up to 10 fingerprints if necessary and can also be opened with your smartphone.

Lithium battery with display

The smart lock is operated by an integrated low power lithium battery. When the battery level is low, a warning signal is displayed on the lock as well as in the app so that you can charge it in good time using the USB cable included in the delivery.

Smart programming via the Smart Life app

Like every Smart Life device, the SIRO Smart Lock can be integrated into all smart programs such as time switching or scene creation in your “Smart Life” app.
