Some vehicles with keyless ignition systems include a key fob that "goes to sleep" after a certain amount of inactivity, providing an extra layer of security. Scammers can't read it and use signal boosters to open the doors from a distance because of this.
I've been looking, but I can't seem to figure out if my Niro 4 has this kind of key fob. Does anyone have any idea?

Is this a "sleeping key" kind of entry fob?

In my owner's manual (2025), you can find a notice on pages 5–11.
Assuming that isn't in your handbook, you should probably put the key in a metal container or do something else to keep it safe.

Thank you. That slipped my mind! Thank goodness for this, because it is'supposedly' a great security feature for keeping the car close to the key.

I would be careful not to leave my fobs lying around because I have no idea when Kia added this feature to them. We continue to store ours in a Faraday box even after I deactivate the car key fob signal.

I just verified that my Niro 3 HEV key will not work if I leave it alone for about fifteen minutes. Holding down the lock and unlock buttons for approximately 5 seconds until the warning lights flash is another way to disable the keyless entry.
