Dynamic problem.... why they jump?

Please can anybody tell me why these keys are all jumping just as soon as they are added? It’s a bound problem? How can I make them stay still?

Here is the blend… If I activate dynamics on the pbject on layer 2 all the replicas will jump as soon as they are added:

for one thing everything is way too small, try scaling everything up about 10X.

Under the keyboard your mesh has all its faces in the wrong direction,
get it into edit mode, press A untill you have everything selected,
then press N to recalculate the normals.

When I run this nothing happens… I have no idea what is being added or what is supposed to happen.
On layer 2 all I see is a Key and an apple logo.
