Box O' Keys?

[UnlockD]

My grandfather passed away, and in his shed we had found four Abus boxes filled with various Abus key cuts.
Anyone have any idea what these boxes are for? My Grandfather was no Locksmith, so I remain clueless.
The keys are all new too, by the way..

If you want, I collect keys, and I live in Ontario..
