eLinkSmart YL-C6BF-Black Chain Lock: Fingerprint and phone app biometric lock
This keyless chain lock is for the bike commuter who needs to secure their ride at a public rack, or the homeowner who wants to grant temporary access to a delivery person without handing out keys. While many locks focus on security, this one offers the convenience of modern access control, letting you manage entry from anywhere.
Unlock it with your fingerprint or phone app, and authorize others remotely when you are out. The waterproof design means you can trust it in rain or snow, with a durable chain that resists cutting. A low battery alert on the app gives you plenty of time to recharge via USB. You will appreciate how the app notifies you instantly when the lock is used, so you always know who accessed your bike or gate.
