HELP! Engine not starting!

Dorchester2 · 30th July 2020, 18:52

After 3 dream journeys in June & July, my V6 refuses to start!
Not the faintest clicking, no ticking, nothing at all when I put the key in the starting position.
Everything is switched on as usual, dash & counters, lamps, radio is able to work.
When I try to start, the fan is stopping as - I assume - it does in such a situation: mind that when the engine is starting and all is fine, I don't notice everything working...

The battery a strong AGM Banner - 2 1/2 years - looks fine, very well cared for, regularly charged and tested gives 12.7V.
The starter - 1 1/2 year - is a nearly new one, sold as refurbished in Nov 2018. I assume that the solenoid was changed and was new.
The car is always garaged when at home.
Not even the slightest mark of moisture or rot anywhere, the whole car is very sound.

I thought it could be the immobilizer but I've successfully tried to open, lock & reopen the car with the fob, and it works fine (red light first clicking fast, then slowly and regularly when car is locked). Could the key not be recognized all the same when inserted?
How could I know if it's the immobilizer or not?

It's scary & I'm lost...
