My 2014 Toyota battery was dead. Suspect trunk was left open for a long time 18hrs I bet after a trip to Costco. Charged battery and decided to put a new battery in. When changing battery the 10mm socket went chink clunk gone thought it hit concrete. Then a 3" extension went clink clang on to the pan in front of radiator, use a long magnetic grabber, got it. It's hot and engine is hot I'm pissed off my bum ankle is barking. Got the battery in and the 10mm socket is under or where ever, don't care. Didn't bother with battery hold down lazy hot me,tomorrow. Wife had to go someplace early so she got back I let the car sit 2 hours put hold down on. Backed car out no socket, OK. Looked in driveway not in site 30 ft of 185' driveway. Drove out end hoping itshook lose from drop off at end driveway, nope. Roll down the road 150' and there it was amazing.
