Once, accidentally dropped keys into boot, as they slopped from my hand as I close sing boot-lid! Oops!
Auto Assist chap arrived, opened driver's door easily, pulled out back seat, & all other paraphernalia. Used a long hook steel rod, through hole in parcel rack, which he said is designed exactly for what he was doing, saw keys easily, hooked them, & brought them out!
Then he put all back together again!
My boot is permanently on 'key lock', so boot auto-release can't be used by a possible thief.
There's a steel wall between back of back seat & boot space. This is for security, & a safety enhancement.
As my house keys were on same ring-chain, I couldn't get into house to get spare car keys, so I was really up s@&$ creek without a paddle!
Thankfully, this was at the end of my day, & I wasn't heading to a medical appt, or a Concert!
Silly, silly me!
I now place keys on rear bumper bar, once I've unlocked boot!
