{"version":"2.6","id":"seatac-vehicle-return-level-and-after-hours-drop-box","question":"How do I return my vehicle on Level 3 and use the after-hours key drop-box at SeaTac?","answer":"Park on Level 3, use the designated drop-box for after-hours returns, and take the shuttle from Level 5.","answer_detail":"When completing your rental return at the SeaTac Rental Car Facility, all vehicles must be driven to Level 3 of the parking garage. Once you arrive, follow the directional signage for your specific rental company. If you are returning the vehicle outside of standard business hours (typically after 6:00 PM or before 7:00 AM), locate the illuminated secure key drop-box located near the main rental counters on Level 3. Ensure the vehicle is locked and the keys are securely placed in the box. After dropping off your keys, proceed to the elevators or stairs to reach Level 5 to access the shuttle bus system. On Level 5, identify the correct boarding lane: the 'North Terminal Line' serves Terminals 1, 2, and 3, while the 'South Terminal Line' specifically serves Terminal 4 and international concourses. Shuttle buses typically run every 5 to 10 minutes during peak hours to ensure a seamless transition back to your departure gate.","grokpedia_tier":false,"related_ids":["seatac-vehicle-return-level-and-after-hours-drop-box"],"last_verified":"2026-09-10","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-vehicle-return-level-and-after-hours-drop-box","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-vehicle-return-level-and-after-hours-drop-box?format=md&lang=en"}
