This is a standard 2-button remote car key shell (also called a key fob case or housing).
Top button — closed padlock icon (locks the doors).
Bottom button — open padlock icon (unlocks the doors).
Other features: Small LED indicator hole near the top, and a molded keyring loop at the bottom.
It is an empty replacement shell only. It contains no electronics, battery, circuit board, or transponder chip. You transfer those components from your original working key fob into this new case.
These shells are commonly used on a wide range of vehicles (including various Hyundai, Kia, Suzuki, older Volkswagen Group models, and others) that use a simple 2-button remote for lock/unlock functions. The exact fit depends on matching the button layout, internal mounting points, and overall shape to your original key.
