CLEVERLOCK is a purely mechanical, battery-free parcel lock with a brilliantly simple trick: Parcel boxes remain closed and weather-protected even when empty but can be opened with a simple push of a finger. After placing the parcel inside, the delivery person closes the box again, which from that moment on can only be opened with the recipient’s key. It’s so easy that it can be fully explained with a small sticker, which we include as standard.

In the initial state, the parcel box door is closed but not locked. Delivery personnel can open it by turning the handle. After placing the parcel inside, they simply turn the handle back and let it snap into place. From then on, the door is locked and can only be opened with the recipient’s key.
Every parcel box with CLEVERLOCK comes with a transparent sticker featuring a brief, illustrated instruction. This can be attached to the door to explain the function to delivery personnel.
