RE: Fluence Keys
VM original car mats are often surprisingly cheap, and come with a 'proper' warranty you can hang them on.
I reach up to the silvered part, rather than touch the paint work (that will probably scratch it). I have also strung a handle across the two rivet holes in the boot liner, which can help lower it but you have to be careful not to pull so hard that it pulls the trim rivets out!
I did try removing one of the support struts so it would fall and close of its own accord once over its natural tipping point. It does, but the boot then sinks (when closed) on the side where the strut is absent and makes it look wonky, because there is a natural pressure in the closed state too which lifts the boot up against the lock position.
