The Magic Key is a British educational animated television series based on the "Biff, Chip and Kipper" stories from the Oxford Reading Tree published by Oxford University Press, originally written by Roderick Hunt and illustrated by Alex Brychta. The series is a co-production between Collingwood O'Hare Entertainment Limited and HIT Entertainment, in association with the BBC and aired within the BBC Schools strand on BBC Two from 2000 until 2001.

Plot

The series centres on the lives of three children, Biff, Chip and Kipper Robinson, their parents, their grandmother, their friends, Wilf and Wilma Page, Nadim Shah, Anneena Patel and the Robinsons' dog, Floppy. Floppy wears a collar around his neck with a golden key upon it. The key is magic, as the title suggests, and seems to do some strange things whenever one of the children asks a question and Floppy wishes for something. It starts to glow and transports the 7 children, Floppy and sometimes the Robinsons' grandmother through a vortex to other worlds, where they have exciting adventures, such as dealing with trolls in a cavern, being characters inside of a computer game, or finding the Fountain of Youth and when the adventure is done, they get a gift and the key glows and they all go home.
