In both cases I am getting a parity error response from the Sim.

Alternatively Tried the KG command in the console which failed too.

Could you assist me in resolving this issue?

Resolved the issue by prepending a U to the keys being sent(this was a solution from a older thread).
Not sure I understand , because the scheme is already included in the A0 message.
