Hirschmann (OEM antenna) key ?

[Lilly]

Does anyone else still have theirs ?  If yes, do you know exactly what they are for?  Antenna raising?
Unfortunately, my dear grandmother is no longer able to inform me about these keys (with Hirschmann symbols stamped into them) which I got from her with the car's ignition, door, and trunk/glove-box keys.
They appear with two teeth oriented like a pair of fangs on a key about the size of a U.S. or Canadien quarter.

A mystery indeed !

If you have the original aerial, it will have 2 slots in the top button. The key is for pulling it up from it retracted (locked) position.
This was to avoid vandals bending/breaking the aerials  :?
