Our most secure Bluetooth padlocks—raised shoulders shield the shackle from bolt cutters and other break-in attempts. Download the app to control who can open these locks and when, even while offsite. Add or remove users, set up a schedule for when they have access, and track the lock’s activity. You can also give short-term access to temporary users, such as contractors or inspectors. Military-grade encryption protects these padlocks from hacking as well. Open the lock through the app, or use a combination if your phone is unavailable. A light indicates when the battery is low. However, dead batteries won’t compromise the security of these padlocks—you won’t be able to unlock them until the battery is replaced.
