Why does the lock have a keyhole but no key in the package?

Question

Accepted Answer

The Xiaomi Front Opening Luggage is equipped with a TSA-approved luggage lock, which is set up to facilitate customs unpacking inspection to prevent violent unpacking. Only the customer scanners' master key can open it. After inspection, the luggage will be relocked and restored. The Xiaomi Front Opening Luggage supports password unlocking without a key in the package.
