How Far Can a Keyless Car Drive Without the Key?

Keyless cars offer significant convenience as they allow drivers to start the vehicle with the push of a button, as long as the key fob is within the vehicle. Some cars can continue to operate even if the key fob is no longer inside the car, raising questions about potential risks. An investigation was conducted where a YouTuber left their key fob at home and drove their car for over five miles without the vehicle shutting down or giving any significant alerts.

This experiment highlights that some cars will indeed continue to run without the key fob within a certain range. However, they may eventually alert the driver once parked and restarted, posing a risk if the car needs to be turned off and on again without the key fob nearby.

Potential Implications for Car Security and Safety

The question, "how far can a keyless car drive without the key?" also brings up considerations about car security. If a car can keep running without the key fob, it could be susceptible to theft, especially in valet parking scenarios where there might be a mix-up if the key fob is not handed to the valet. It raises potential risks such as the car being driven away or being left in an unintended location without the ability to be restarted.

Modern Car Technology and Precautions

Modern cars often have systems that warn drivers when the key fob is out of range, helping to mitigate the risks of driving without it. However, it's essential to follow the manufacturer's guidelines and ensure that the key fob is always present to avoid these issues. Key fobs work as transmitters with a unique ID that communicates with the vehicle, not just for starting it but also for security features like locking and unlocking doors.
