Car key shell (remote keyless entry transmitter)
This is a standard automotive remote control key fob used to lock, unlock, and operate certain functions of a vehicle without inserting a physical key.
Button functions (from top to bottom):
Top button (closed padlock icon): Locks the doors.
Middle button (car silhouette): Typically opens the trunk/boot or hatch.
Bottom button (open padlock icon): Unlocks the doors.
The small circular mark near the top is usually an LED indicator light. The metallic section at the bottom often houses a mechanical key blade (which slides out) or a panic/alarm button, depending on the exact model.
This particular design is commonly associated with Hyundai and Kia vehicles (and some related brands).
