Trevisan~\cite{Tre03} suggested a transformation that allows amplifying the error rate a code can handle. We observe that this transformation, that was suggested in the non-local setting, works also in the local setting and thus gives a generic, simple way to amplify the error-tolerance of locally decodable codes.
Specifically, this shows how to transform a locally decodable code that can tolerate a constant fraction of errors
to a locally decodable code that can recover from a much higher error-rate, and how to transform such locally
decodable codes to \emph{locally list-decodable codes}.

The transformation of~\cite{Tre03} involves a simple composition with an \emph{approximately} locally (list) decodable code.
Using a construction of such codes by Impagliazzo et al.~\cite{IJKW10}, the transformation incurs only a negligible
growth in the length of the code and in the query complexity.
