Securing your bike at a public rack or your backyard gate shouldn't mean relying on a flimsy lock. The Blue Y787 Smart Alarm Lock gives you app-based control and a high-decibel deterrent. Instead of fumbling for keys, you arm and disarm from your phone. The real advantage? The lock's motion sensor triggers a loud siren the moment someone tries to cut or shake it.
You get an instant push alert, so you can react before the thief succeeds. It's weather-resistant and mounts easily on gates or bike frames. The battery lasts months, and the companion app shows lock status in real time. This isn't just a lock—it's a remote security system for your valuables.
