Redis key expiration management covers essential commands like EXPIRE, TTL, and PERSIST for controlling data lifetimes. The tutorial demonstrates setting expiration times in seconds and milliseconds, checking remaining time with TTL commands, and understanding return values (-1 for persistent keys, -2 for expired/deleted keys). Key concepts include using SETEX for combined set and expire operations, PERSIST to remove expiration, and PEXPIRE/PTTL for millisecond precision. Updates to expired keys don't reset expiration times, requiring manual renewal with additional EXPIRE commands.
