The panic button on your car key fob is designed as a safety feature for emergencies. Its primary purpose is to attract attention by triggering the car's horn if you feel threatened or need help near your vehicle.
While many drivers use it to locate their car in a crowded parking lot, this is a clever secondary use, not its main function. The loud alarm can also deter potential thieves if you see someone suspicious near your car.
Most panic buttons require a press-and-hold action to activate, reducing accidental triggers. Even as digital keys become more common, the physical key fob retains this valuable safety tool.
