This is the amusing moment a family sent a toddler through a window to unlock a door after they found themselves locked out of their home.

Shiena Villamor and her relatives had just returned from a dinner celebrating her aunt's birthday in Masbate, the Philippines, when they realised they had forgotten the house key.

With no way to enter, the family decided to let three-year-old Diandra Selena climb in through a window on June 20 evening.

Footage shows the child's grandfather lifting her up to the opening and carefully lowering her onto a sofa inside.

The agile toddler then rolled off the couch and made her way to the door, prompting laughter from relatives waiting outside.

Diandra successfully turned the doorknob and opened the door, allowing her aunt to step in first.
