Redact The Key

Star out everything after the sk_live_ prefix, however long the key is, leaving other text untouched.

A replacement string cannot count, so you cannot swap the whole key for a fixed run of asterisks. Replace one character at a time instead, and use a lookbehind to ask "is there a sk_live_ back there?" — JavaScript lookbehinds are not limited to a fixed width, which is what makes this possible at all.
