Network key updates

I am hoping to use XBee ZB modules using AT interfacing, in a cable replacement application. I planned to use the standard security but was a little concerned by what I read about the Frame Counter reaching a maximum count and then no further communication being possible.

Agreed, 13.6 years is a long time but being convinced that if something can go wrong it will, I figured it would be good to have some defence against it. The answer, it appears, is on page 71 of the User Manual:

“ZigBee supports a mechanism for changing the network key in a network. When the network key is changed,
the frame counters in all devices reset to 0.”

The problem is I can’t find out how to access this mechanism via AT commands. Is it possible to do this?
