Is there a distance limit for the car's remote start function?

[VonSamantha]

Generally, the effective distance of a car remote key is within 30-50 meters, and the effective distance will be farther without obstacles blocking the signal. If using a smartphone to remotely start the car, it can be controlled from anywhere with a signal. Below is relevant information: 1. The remote start function allows starting the vehicle without manually entering it, but through remote control. The principle is to send a signal via the key or smartphone to remotely start the engine. Smartphone remote control of the car utilizes wireless communication technology, with the basic principle being the use of software in the phone to control the car's built-in hardware and software for remote operation. 2. Smartphone-controlled one-button start. When the owner enters the car, pressing the one-button start can start the car, eliminating the inconvenience and hassle of taking out the key and inserting it into the ignition.
