Radio comes back on after locking car.

[Kilroy]

2004 VY Wagon.
Hi,
An intermittent fault,
1, when stopped and turned off, then remove key and open the door, the radio turns off,
then when I get out n lock the door the radio comes back on,
This has happened on and off for a few years, and seems to occur more in cooler weather.
I’m hoping it’s not a dry joint in the computer.
Vehicle did this with Stock radio and fault is still the same with aftermarket radio.
Any thoughts please?

what does the interior light do

As per the other thread, the solution is the antenna. Caused by water ingress into the plug. Plug is located behind the left wheel well cover.
Remove the wheel. Remove the cover/trim panel in the wheel well, then unplug the antenna or replace the antenna.
