Yes, but did you find your keys?
I lost the bolt that fastens the tailplane on my pegasus glider at RAF Benson in the tall grass. Didn't realise it was missing until attempting to rerig the glider next morning.
Fortunately my son in law had a metal detector.
We rolled up to the gate at Benson, were escorted to the scene of my arrival the day before, and fortunately the tracks were still visible in the grass...
The Military Policeman said "that looks like a neat gadget, can I have a go?"
and on his first sweep over the grass it got all excited. There, hiding, was the bolt, still firmly clutched in the grip of the derigging tool!
