6.6.9 Write a key to a card

  WRITEKEY [--force] keyid

This command is used to store a secret key on a smartcard. The allowed keyids depend on the currently selected smartcard application. The actual keydata is requested using the inquiry KEYDATA and need to be provided without any protection. With --force set an existing key under this keyid will get overwritten. The key data is expected to be the usual canonical encoded S-expression.

A PIN will be requested in most cases. This however depends on the actual card application.
