## What to know

For after-hours returns at the SeaTac Rental Car Facility (located at 3140 S 192nd St, SeaTac, WA 98188), follow these precise steps. First, enter the facility's parking garage and proceed to the designated National floor, which is Level 4. The garage is open 24/7, and signage directs you to the correct level. Once on Level 4, locate any available parking spot within the National section. Pull your vehicle forward until the front tires touch or are within 6 inches of the curb or wheel stop—this ensures the vehicle is fully within the space and avoids obstruction. Do not leave the vehicle running; turn off the engine, remove all personal belongings, and lock the doors. Then, walk to the secure key drop box, which is a metal box mounted on the wall near the elevator bank on Level 4. The box is clearly labeled with a “Key Drop” sign and is accessible 24 hours a day. Insert your rental agreement and keys into the slot. The entire process typically takes 3–5 minutes. Note that after-hours returns do not incur an additional fee, but you must return the vehicle by the time specified in your contract to avoid a late charge of up to $50 per day. The facility is monitored by security cameras, and the drop box is emptied every 2 hours overnight. If you encounter any issues, call the 24-hour customer service line at 1-800-227-7368.
