before put key you need to do authenticaion of GP'S Channel.

I have established secure channel before PUT KEY command.

Status ‘69 82’ is "Invalid key check value",so New Key: 101112131415161718191A1B1C1D1E1F, data = 0000000000000000, KeyCheckValue = FE 8A 09, algorithm is DES. and encrypted Key - 3DES_ECB(new key) with ENCSessionKey . so PutKey APDU = "80D8008143 + 01 + 8010 + encrypted + 03 + KeyCheckValue + 8010 + encrypted + 03 + KeyCheckValue + 8010 + encrypted + 03 + KeyCheckValue ".
