Keypers were made in the 1980's by Tonka and consisted of large, hard plastic bodied adults and small soft plastic bodied babies. The adult Keypers had a key (with their name on) which locked and unlocked a door somewhere about their body, and the baby Keypers had a slit in their backs where you could store things.

The first series of adult and baby Keypers had six different animal types (including two with variations). They all had non glittery eyes and short, mono coloured hair, whilst the second series had 11 pairs with glittery eyes and long, multi coloured hair. Five of these pairs were reissues from the first series, some looking quite different, and there were also six new additions. All adults came with various accessories including a key, brush & a keyring which they both slotted onto. Some also came with hats and neck frills. The babies also came with brushes (slightly smaller than the adults, no loop at the end for the keyring) and other accessories such as bottles and bibs.

Along with the plastic toys there were large plush adult Keypers, books, games and other items.
