Control who can open these locks and when they can open them—even when you’re offsite. Download this lock’s corresponding app to 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 also protects these padlocks from hacking. Use the app to open the padlock, 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.

More secure than standard padlocks, they have a shackle that’s protected by shoulders, making it difficult to access and cut. Its shackle is made of boron carbide, the hardest and most cut-resistant shackle material. With a body made of powder-coated zinc and a thermoplastic cover, these padlocks are good for outdoor use because they resist rain, snow, and temperature changes.
