A Remote Start System is a feature in vehicles that allows the driver to start the engine from a distance using a key fob or smartphone app. This technology is particularly useful in extreme weather conditions, as it enables the car to warm up in winter or cool down in summer before the driver enters. These systems typically work within a specific range, often around 300 to 1,000 feet. Some advanced models can integrate with smart home systems or offer additional features like locking/unlocking doors and activating the vehicle's climate control settings remotely.
