You can't get the key value.
You can dec command message with ENC session Key (Not S-ENC key);
and enc/dec sensitive data with DEK session Key (Not DEK key);
and verify command MAC with MAC session Key (Not S-MAC key).
For more details please see GlobalPlatform Card Specification 2.x.x.
sense and simplicity
