Being a scatter brain lately I've lost the key that opens the gas box to
get at the meter. It has a triangular shape and the key is plastic.

Any ideas how I can find one of these keys so I can get to the meter

...its a pre payment gas meter which is low .. and its top up time :-s

I did call the gas company I'm with and they said they dont sell any
such keys.

from a quickie google.
