Where I can buy additional cards ?

Hi friend, thanks for your question. Our locks support RFID cards with a frequency of 13.56mhz. You can buy it at your local store.

Does the smart lock automatically turn the cylinder or shall it be turned by hand to lock/unlock the door?

Hello, it is a smart lock that is manually unlocked. You need to manually turn the handle to unlock

Does it have a manual key incase of battery died?

Manual in Chinese.. Very poor details in English
