	n can be one of the following values:
	M	– master key (key is in clear text)
	S	– session key (key is encrypted under Master Key)

0 ... 3 – lower working keys (key is encrypted under Session Key) A ... J – upper working keys (key is encrypted under Session Key)

key is the 16- or 32-character value of the key to be loaded.

Errors /load_key 30<LF>

If the n field is invalid, key is the wrong length, or the device sends an error (e.g., there is a key parity error).

/load_key45<LF>

If the required key is not loaded.

Remarks This command is used to load a key into the device. With all but the master key, the selected key is encrypted under another key so the application must know the encrypted value of the key. The response to this command is: /load_key SS

SSis a two digit status code; 00 – success, 30 – invalid, 45 – rejected, etc.

Example To load the session key encrypted under the master key:

Command /load_key S 99E1E835662DEA94<LF>

Response /load_key 00<LF>
