how far can a keyless car drive without the key

The distance a keyless car can drive without the key varies depending on the vehicle’s make, model, and year. Here are some general guidelines:

1. Most keyless cars: Typically, a keyless car can continue to run for a short distance (usually around 1-5 miles or 1.6-8 kilometers) after the key is removed from the vehicle or goes out of range. This is because the car’s onboard computer has a temporary memory of the key’s presence, allowing it to continue running for a short period.
2. Some luxury cars: Certain high-end vehicles, like some Mercedes-Benz and BMW models, may have a more advanced keyless system that allows the car to continue running for longer distances (up to 30 miles or 48 kilometers) without the key.
3. Cars with "keyless go" systems: Some vehicles, like those from Audi and Volkswagen, have a "keyless go" system that allows the car to start and run without the key being physically present. In these cases, the car may be able to drive indefinitely without the key, as long as the key is within a certain range (usually around 10-15 feet or 3-4.5 meters).
4. Cars with "remote start" systems: Some vehicles have a remote start system that allows the car to start and run without the key being physically present. In these cases, the car may be able to drive for a short distance (usually around 1-5 miles or 1.6-8 kilometers) without the key.

It’s essential to note that these distances are estimates and can vary depending on the specific vehicle and its keyless system. Additionally, if the key is removed or goes out of range while the car is in motion, the vehicle may enter a "limp mode" or shut down to prevent unauthorized use.

To avoid any issues, it’s always best to keep the key with you while driving a keyless car. If you have any concerns or questions about your vehicle’s keyless system, consult your owner’s manual or contact the manufacturer or a dealership for guidance.
