What are the after-hours key drop and return procedures for off-airport vendors at the SeaTac Rental Car Facility?

When returning your rental vehicle to an off-airport vendor at the SeaTac Rental Car Facility outside of standard operating hours, you must follow specific procedures to avoid additional charges. First, enter the SeaTac Rental Car Facility located at 3150 S 160th Street. Proceed to the designated parking area for off-airport vendors, which is clearly marked on Level 1. Park your vehicle in any available space within the designated off-airport vendor rows. Before exiting the vehicle, ensure you note the exact mileage and fuel gauge level, as you will need to document these on the after-hours return slip. Take all personal belongings and remove any trash. Lock the vehicle securely. Next, locate the designated after-hours key drop box situated at the off-airport vendor kiosk near the Level 1 elevators. Complete the return slip with your name, rental agreement number, exact mileage, and return time. Place the keys and the completed slip into the secure drop box. Vehicles returned after hours will be processed by the vendor the following business day, typically opening at 8:00 AM. Please note that the renter remains fully responsible for the vehicle's condition and any parking violations until the vendor processes the return the next business day.
