Our Secure models operate on 4 AA batteries, while the Vision model uses 8 AA batteries. We recommend using high-quality brands like Duracell or Energizer. Avoid using rechargeable or lithium batteries, as alkaline batteries have proven to be the most effective with our locks. Typically, batteries last 9 months to a year with normal use and 6-9 months with heavier use. Duracell or Energizer alkaline batteries are preferred for optimal performance.

Our locks feature an indicator light and an app notification to alert you when the battery is low, and the lock will also beep as a warning. If the batteries completely drain, you can still power the lock with a 9V battery by holding it against the connector on the bottom of the exterior side of the lock, allowing you to enter your door code and unlock the door. Not to mention you will always be able to use the physical key.
