The standard Subaru key fob typically includes four core buttons: Lock, Unlock, Trunk Release, and Panic. Some models add a Remote Start button.
Beyond the basics, the exact symbols, layout, and availability can vary by model and year. Remote Start is only on certain trims, and newer Subaru systems may use a Smart Key setup that changes how you interact with the fob. The following explains the common buttons and how they’re used across popular Subaru models.
Core buttons and their functions
Lock button
The Lock button secures all doors and typically engages the vehicle’s alarm system. On many models, the exterior lights flash and the horn may chirp when the doors are locked, signaling that the vehicle is secured.
Unlock button
The Unlock button releases the door latches. Depending on the vehicle’s settings, a single press may unlock the driver’s door or all doors, and some models offer additional options via the infotainment system for driver-only access.
Trunk release
The Trunk Release button opens the hatch or trunk. In some models, you may need to press and hold the button to prevent accidental openings, or the function may be combined with other unlock features depending on trim and year.
Panic button
The Panic button triggers the car’s alarm, causing the horn to honk and lights to flash. This is intended to deter theft or help locate the vehicle in a crowded parking lot.
Remote Start (if equipped)
Remote Start enables the engine to start remotely, warming or cooling the interior before you enter. This button (often shown with a circular arrow around a car) or a combination action on the fob is available only on select models and trims. Check your owner’s manual for the exact method and safety guidelines, as procedures vary by year and configuration.
Model-year and trim variations
Most current Subaru SUVs and sedans share the four-button layout, but some trims add a dedicated Remote Start button or a trunk-hatch function. Older models or regional variants may omit Remote Start or use slightly different iconography. Some models with Subaru’s Smart Key system also offer proximity unlocking, which can affect how you interact with the fob, even though the physical buttons remain familiar.
How to identify your fob’s layout
Check your owner’s manual or the dealer’s documentation to confirm the exact button layout for your year and trim. You can also compare your fob against official Subaru images for your model, or contact a Subaru service center for a replacement that matches your vehicle’s specification.
Summary
In most Subaru key fobs, you’ll find four core buttons: Lock, Unlock, Trunk Release, and Panic. Many models also offer Remote Start on higher trims. Button availability and exact icons vary by year, model, and whether you have a standard or Smart Key system, so always consult your manual or dealer for your specific configuration.
