Same - Had a similar experience myself Ian in the first week of getting the car

.
I opened the boot with the fob, then put the fob in the back pocket of my jeans.
Reached back into the boot for the second time and retrieving some items at the back of the boot, I suddenly heard the beep beep beep of the boot closing !.
Just managed to get my head out of the way in time - phew close shave

.
I think what must of happened is this.
Never wanting to shut the key inside of the boot, I never put the keys down inside of the boot.
Straight into my back pocket, but I think that when reaching inside, the button somehow the close button on the fob, must of got depressed

.
Never happened since tbh.
This is the first car that we have owned with an electric opener and it’s a big help !.
The only issue is that my wife finds it a little difficult to reach the close button in boot lid when it is open.
A little vertically challenged is the correct terminology now if you are a little short in height I believe
