It’s completely understandable — situations like this can happen, and a dead phone battery is a common issue.
While the Serea lock can only be opened via the app, it isn’t tied to just your phone. Instead, it’s linked to your account. That means you can access and unlock it from any smartphone with an NFC antenna, as long as you can log into your account.
What does this mean in practice?
Simply borrow the phone of a friend, colleague, or basicly anyone. Download the Serea App, log in, and you’ll be able to unlock your Serea lock right away.
