How long do the batteries last?

A battery pack (4xAAA) lasts approximately 10,000 to 15,000 openings, depending on the quality of the batteries and the usage of the lock, which equals an average use of about a year.

The level of the batteries is updated in real time in the application that sends to the customer's smartphone the capacity as a percentage of the lock batteries, as well as an alert with the information that the batteries should be exchanged.

If the lock goes out of battery, in addition to the opening with mechanical key, there is also a Micro USB port accessible from the outside to power the lock through a powerbank or smartphone charger, for example, and can then use an access credential to open the door and replace the batteries.
