Can Car Keys Be Duplicated?

Car keys can be duplicated. Below is relevant information about duplicating car keys: 1. Methods for duplicating car keys: A 4S store can query the anti-theft code for configuring the key from the database based on the vehicle registration certificate and the owner's ID provided by the car owner. After obtaining this code, the 4S store requires the owner to provide the key tooth shape number to configure a new metal key. 2. Function of the old key: After the car key is successfully matched, the new key can be activated, and the lost key will immediately become invalid. Even if someone finds the old key, they can only open the car door mechanically but cannot start the owner's vehicle. Therefore, the security level of this 'code' becomes a major factor determining the price.

When visibility is less than 100 meters, what should the speed and distance between vehicles be maintained at?

When visibility is less than 100 meters, the speed should not exceed 40 kilometers per hour, and the distance between vehicles should be maintained at more than 50 meters. Below is more relevant information: 1. Precautions for driving on highways: (1) Enter the driving lane correctly. When a vehicle enters the highway from the ramp entrance, it must increase speed in the acceleration lane and turn on the left turn signal. When it does not affect the normal driving of vehicles in the driving lane, it can enter the driving lane from the acceleration lane and then turn off the turn signal. (2) Maintain a safe distance. When vehicles are driving at high speed, the following vehicle in the same lane must maintain a sufficient safe distance from the vehicle in front. (3) Overtake with caution. When overtaking is necessary, first observe the state of the vehicles in front and behind, and turn on the left turn signal at the same time. 2. Relevant regulations: When visibility is less than 200 meters, turn on the fog lights, low beam lights, clearance lights, and front and rear position lights. The speed should not exceed 60 kilometers per hour, and the distance from the vehicle in front in the same lane should be more than 100 meters. When visibility is less than 50 meters, turn on the fog lights, low beam lights, clearance lights, front and rear position lights, and hazard warning flashers. The speed should not exceed 20 kilometers per hour, and the vehicle should exit the highway from the nearest exit as soon as possible.

Does a Car Spoiler Save Fuel or Consume More?

In general, it consumes more fuel. Some car models come with spoilers because they prioritize performance, as the spoiler can provide additional downforce at high speeds to ensure vehicle stability. Therefore, spoilers can also be considered a safety feature. However, currently in China, most spoiler modifications are primarily for visual appeal. Below is more information about car spoilers: 1. Introduction: The professional term for a car spoiler is "automotive spoiler" or "rear wing." It is part of the aerodynamic kit of a vehicle. 2. Function: The main purpose of a spoiler is to reduce lift at the rear of the vehicle. If the lift at the rear is greater than at the front, it can lead to excessive oversteer, reduced rear-wheel traction, and poor high-speed stability. 3. Advantages: Apart from enhancing aesthetics, the primary benefit of installing a spoiler is providing necessary stability at high speeds. Especially for high-performance cars, spoilers can help maintain balance during high-speed cornering or on complex road sections. 4. Disadvantages: The fewer protrusions on a car's surface and the smoother the lines, the lower the aerodynamic drag. Adding a spoiler increases drag. Since most sedans primarily drive on urban roads, they rarely reach speeds where spoilers are effective. The larger the spoiler, the greater the low-speed resistance, and the additional weight of the spoiler will inevitably lead to increased fuel consumption.

What to do if you find your car scratched a few days later and don't know where it happened?

If you find your car scratched a few days later, you can retrieve surveillance footage from the residential community or property management company to identify the responsible party. If the incident occurred at an intersection, you will need to request assistance from the nearby traffic police department (road administration unit) to obtain the intersection camera records. If the scratch is severe and results in costs exceeding a thousand yuan, you should file an insurance claim and let the insurance company handle the compensation. Below are the methods to deal with scratches: 1. Polishing: If the scratch is deep and waxing doesn't work, polishing can help remove it. 2. Dents after scratching: If the scratch causes a dent, you will need to visit a repair shop for panel beating, painting, and reshaping. 3. Touch-up paint pen: If the scratch exposes the primer, it's important to repair it as soon as possible to prevent rust after rain. If you can't repair the car immediately, you can use a touch-up paint pen to cover the primer temporarily to avoid rust.

What are Niu Ma Lun cars?

Niu Ma Lun refers to Ferrari, Lamborghini, and McLaren respectively. These are supercar-class vehicles. Below is an introduction to sports cars: 1. Definition: The English name for sports cars is SportsCar or SportyCar, belonging to a type of automobile characterized by low chassis, streamlined contours, and outstanding power. 2. Features: Their most notable feature is the relentless pursuit of speed limits. Sports cars can be classified in various ways—by body structure into coupes, convertibles, and two-door sports cars, or by value into affordable sports cars and supercars. 3. Vehicle Classification: The following categories do not encompass all sports cars, as gaps still exist. Some two-door or even four-door coupes are also referred to as sports cars but are not listed here. Some sports cars possess at least two attributes, particularly high-performance vehicles with sedan-like appearances and superior acceleration capabilities.

What Causes the Emission Exceedance Warning Light to Illuminate?

Emission exceedance warning light illumination is caused by a damaged catalytic converter. Below is more relevant information: 1. Principle: When the computer receives parameters from the oxygen sensor indicating that the tailpipe emissions severely exceed national legal standards, and the internal program cannot adjust them back within the standard range, the engine control computer will then trigger the pollution emission exceedance warning light (yellow pollution light) on the dashboard to alert the owner to check the engine's pollution emission light at a service station. 2. Reasons for the pollution light to illuminate: (1) Poor gasoline quality can lead to incomplete combustion of the air-fuel mixture in the cylinders, causing the pollution light to illuminate and also easily leading to carbon buildup. (2) Carbon deposits in the intake tract or on the piston crown can result in poor atomization, leading to incomplete combustion and causing the pollution light to illuminate. (3) During cold starts, especially when temperatures drop sharply, the computer's temperature correction may cause the pollution light to illuminate during startup. However, once the temperature stabilizes at a certain level without fluctuations, the light will stabilize accordingly.
