{"version":"2.6","id":"seatac-after-hours-returns-process","question":"What are the after-hours key drop-off instructions at the SeaTac Rental Car Facility?","answer":"Park in your brand's Level 1 or 2 return lane, fully lock the vehicle, then deposit your keys and signed rental agreement in the secure after-hours drop box at your company's return area.","answer_detail":"If you return your rental vehicle when your company's counter is closed at the consolidated SeaTac Rental Car Facility (RCF), follow the standardized after-hours key drop-off protocol used across all brands at 3150 S 160th Street, SeaTac, WA 98188. The building remains physically accessible 24 hours a day, 7 days a week, and vehicle returns are accepted around the clock even when staffed counters are closed-though major brands such as Avis, Enterprise, Hertz, National, and Budget typically operate from approximately 6:00 AM to 1:00 AM, while smaller specialty brands may close as early as 10:00 PM.\n\nStep 1: Follow airport \"Rental Car Return\" signage to the RCF entrance and proceed to your rental company's designated return lane on Level 1 or Level 2 of the parking structure. Step 2: Park only in the marked spaces assigned to your brand; do not leave the vehicle in shuttle lanes, fire zones, or another company's rows. Step 3: Fully lock the vehicle-close all windows, remove personal belongings and toll transponders not included with the rental, and ensure the ignition is off. Step 4: Complete any mileage or fuel-level fields on your rental agreement if required by your brand. Step 5: Locate the secure after-hours drop box mounted near your company's return counter or return lane. Deposit both the vehicle keys (including any fob or spare key issued at pickup) and the signed rental contract into the tamper-resistant slot. Avis customers, for example, are instructed to use the key drop box at the Level 1 return counter.\n\nRetain a timestamped photo of the parked vehicle, odometer reading, and drop-box location for your records. Note that some rental companies may assess an after-hours service fee-commonly between $10 and $25-if staff were not present to process the return in person; verify your brand's policy on your reservation confirmation before drop-off. After returning the vehicle, use the free 24-hour airport shuttle from the RCF to the terminal; shuttles generally depart every 5 minutes and reach SEA in about 8 minutes (roughly 2 miles). If you cannot locate your brand's drop box, contact your rental company's 24-hour roadside or customer service line listed on your contract before leaving the facility.","grokpedia_tier":false,"related_ids":["seatac-after-hours-returns-process"],"last_verified":"2026-06-22","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-after-hours-returns-process","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-after-hours-returns-process?format=md&lang=en"}
