What to do if the smart lock runs out of battery?

What if the battery runs out? This is a crucial issue as it relates to whether the user can get home, so it's very important. In fact, users don't need to worry about battery life. Firstly, the power consumption of smart locks has been handled very well, and a set of smart lock batteries can last for at least 8 months. Secondly, smart locks all have emergency charging interfaces, so you can use a power bank and a phone data cable for emergency charging. Additionally, if the battery is really dead and you don't have a power bank, you can still use the mechanical key. It's worth mentioning that most smart locks now have low battery reminders, so there's basically no need to worry about battery life.

However, we want to remind users not to neglect their keys just because the smart lock is too convenient. It's best to keep a mechanical key in the car, just in case.
