Keep the key circuits switching cleanly with the Standard Ignition Ignition Switch / Ignition Starter Switch US-571, a bolt-on, column-mounted replacement for the 1993-1997 Lexus GS300 [All]. The ignition switch directs battery power through the start, ignition, and accessory circuits as the key is turned, so a worn or failing switch is a common cause of a no-crank, intermittent-start, or dead-accessory complaint — if the original switch is the cause, this replaces it.
