How Long Can a Car Keep Running After the Key Is Taken Away?
2 Answers
As long as the engine is not turned off midway, the car will usually only alert that the key is not in the vehicle but will not shut down automatically. Below is relevant information about car keys: 1. Number of keys: Vehicles come with 2-3 keys. When a new car is handed over to the owner, the salesperson usually reminds the owner to keep the keys safe. 2. Key code: The keychain for a new car consists of 2-3 keys and a metal or plastic piece. On this metal or plastic piece, there is usually a series of numbers printed, which is the key code. Service centers or manufacturers can use this key code to reconfigure keys for the owner.
I've been driving for almost twenty years, and this kind of thing might work on older cars, but don't expect it to last long in today's vehicles. Last time I was repairing my car, I accidentally pulled out the key, and the alarm went off before the engine stopped. Modern cars are basically equipped with anti-theft systems; as soon as the key is removed, the car's computer immediately detects it, and the engine shuts off within seconds—very safe. Why is it designed this way? Mainly to prevent car theft; if the car could keep driving, it would be a big problem. In the past, with older models, the engine could idle for a few minutes after the key was removed, but with technological advancements, the protection is stronger. I recommend everyone to understand their own car's features and not to curiously test this out—it's easy to cause accidents and damage the car. Especially with some high-end SUVs, they're even more sensitive, so don't take the risk.
