Ah, you read my mind!
I think it's a smashing top mate, especially using the disengaged handbrake as a failsafe measure. I could never quite wrap my head around why Subaru never implemented a remote-boot open on their keys. It has been standard on many lesser value cars for many years now.

Would it possible to have the boot keyhole removed altogether, and operated only via the key?

The thought of added security, and a clean boot lid is very appealing to me
