VEVOR Package Delivery Boxes for Outside, 35.8 in Mailbox for Parcel with Lock, Galvanized Steel Package Drop Box with Anti-Theft Design, Weather-Resistant Package Mailbox for Home and Office, Black

English: Thank you for your questions! The mail/parcel slot does NOT have a lock; it uses a magnetic design for easy delivery. Only the main large storage door is lockable, and you do NOT need to give keys to the postman—couriers can drop packages directly through the slot.
