also many places are non magnetic which would be great places, but since my 'hood' does not lock, many metal places there, and convenient but gas tank area is a nice backup !!
first thing i did when i found someone who could accurately make trimark keys, not the ace h/w and a few others i tried, made 5 sets of keys and have backups all over (+ 2 for ex wifey !!).
but since a lockout of car w/ engine running 30yrs ago, i now ALWAYS carry to sets of keys, 1 in left pocket, 1 in ignition, guess what, never have been locked out since !!
also never had to call lock smith, and was able to get wire coat hanger twisted in 5 ways to finally open that door 30ys ago, PIA plus was in country side and had to beg a wire rack too - and hot !
