The only way to change the signing key for an app (on an unrooted phone at least) is by completely uninstalling it (which deletes the main data directory) and then installing a new version.

[1] I'm 90% sure that a Google engineer admitted it on their official blog, but that was 2 years ago so I might be misremembering it.
