Multiple ADP keys in APX?

[N1GTL]

An APX6500 has a system programmed that uses ADP encryption. The customer would like to add a second system that uses a different ADP key. They have purchased the enhancement that allows multiple ADP keys. When reading a radio, the ADP key is ****** out. I do not know the key for that system.

My question:
If I add the enhancement, can I put a second system in, add that ADP key and program the radio or must I know the ADP key of both systems and enter both. I know generally when you read a radio to clone, it will not let you without retyping the ADP key. The original code plug is normally needed. I just have not run across this request before.

Reading a radio will never reveal the key.
I've never done it but I would venture to guess that when the entitlement is added that it could wipe out the existing key. The only thing you need to know is what Key ID is used for the other system so that you don't use it for the other key that is being put into the radio.

Reading it and then writing to it won't delete the existing key unless there is a key retention setting on other than infinite key retention.

The guys over at commtechforums might be of more help.

I don't have a need for the existing key. I just have someone who wants me to add the multi-key enhancement and put another system in. I don't want to erase the existing key accidentally as that is the system the user would prefer to have until we know what will happen.

You need to know both keys to write the radio. Keys include the key index. All fields except the actual shrouded key must be unique.

Thanks for the info.

If you don't type in the ADP key already in the radio you wont be able to write the radio unless you delete the unknown ADP key.
