I've also been looking for the Walk-Away, Auto-Lock feature on my 2026 Sportage SX HEV Prestige. Based on what I'm seeing in the manual, that feature does NOT exist. Instead, the manual offers only, "Pressing the button on the front door handles with all doors closed or any door unlocked, locks all doors." If walk-away auto lock was available, pressing the button on the front doors would kinda stupid if you could just...walk away and lock all doors. Others have suggested finding the "feature" in the infotainment system under Settings, but auto-lock is not there as an option. The only other option is using the Fob.
There must be a reason why this was omitted. I had this option on my 2019 Honda Civic, and I used it constantly.
