One, if the hotel door lock flashes red when using a card, how to open it?
1、 Battery power is insufficient.
If the battery in a hotel door lock is depleted, you can call the service personnel to replace it.

In this case, it is essential to immediately replace the battery. Please ensure the use of alkaline batteries.

There are several possible reasons for a malfunctioning key: One is that the key's validity period has expired, resulting in its failure.
