I hear many people saying that updating keys with remote controler is imposibile. Lets take as a example Polsat key. Polsat have two keys One is 007101 I ECM 00 / ************** and other 007101 I ECM 01 / ************** To change 00 key you do like this. Go to the keys INSTALLATION-KEY EDIT-KEY EDIT -on your remote controler press EPG buton and search for Nagravision->Cryptworks and search for key with ID 007101 / I ECM / 00 / and delete the old key by pressing BLUE button on remote controler. Now press UHF button on remote and start writing the new key from the bigining of the row including CAID,Provider, Type,Index,Key Data.(SEE PICTURE) WRITING Key Data To write the Key Data you must know how to use remote controler buttons. UHF=A, SPEAKER=B, ZOOM=C, EPG=D, PAUSE=E&F For numbers use NUMBERS ON REMOTE from 1,2,3,4,5,6,7,8,9,0 While writing the Key Data you will not see the numbers changing but just write them by using remote numbers and leters. Write all infos including CAID / PROVIDER/TYPE/INDEX/ KEY*** When you finish writing the first part of the key from 16 numbers press OK and go to the last row of keys and you will see the key that you wrote saved on the bottom of the list. Now select the second row of "007101 / I ECM / 00" press OK and write only Key Data . Press OK to save and exit. DO NOT RESET KEYS AFTER YOU HAVE WRITTEN THE KEY. To change key "007101 / I ECM / 00" do the same like with 00 key. To change key for D+ do the same Key for D+ ''CAID=1801,PROVIDER=004101,Type=I ECM, Index 00 and 01. For Cabo changing key -procedure same like for D+and Polsat "CAID=1801,PROVIDER=004901,Type=I ECM, Index 00 and 01."
