Cayenne key battery

[Cayenneand996]

Has anyone changed their 955 cayenne key battery? My car occasionally shows a warning on the display to say change key battery

Is this just a straightforward battery swap - is there anything to look out for

I assume their is another battery that keeps the memory of the programmed key or does the key need re-programming after

[hadenough!]

Straight swap

The car will remember the key.
