Car mechanical keys can be duplicated, but for car keys with built-in chips, they must be configured at a professional 4S dealership. Keys duplicated on your own can only be used to open the car door and cannot start the car, as the original key contains an anti-theft chip that requires specialized decoding and encoding equipment for proper configuration. Below are the functions of car mechanical keys: 1. Close windows after turning off the engine. 2. Locate the car in a parking lot. 3. Automatically open the trunk. 4. Remotely open windows. 5. Open the driver's side door. Below is the principle of car mechanical keys: They consist of a transmitter and a receiver. Powered by a battery, the key emits a low-power radio wave, which is then received by the car's antenna. The electronic control unit (ECU) identifies the specific signal code, and the system executes the actions of locking and unlocking.

How Long Does an ETC Lithium Battery Last?

Generally, the battery in an ETC device can last for about 3 years under normal usage. For solar-powered ETC devices that are not frequently used, it is recommended to charge them every 3 months to prevent natural discharge of the internal battery. ETC devices have an internal battery and are charged externally via solar power, so they do not require regular charging. ETC stands for Electronic Toll Collection, which is an electronic toll system. To apply for an ETC, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent must also present their valid ID card. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is required. Applicants must be between 18 and 60 years old, and the vehicle must be registered under a personal name. For company vehicles, the required documents include: A letter of introduction from the vehicle owner (with official seal); a photocopy of the organization code certificate or business license (with official seal); the agent's original ID card; the original vehicle registration certificate; and the vehicle for which the ETC is to be installed. How ETC works: The system uses an onboard electronic tag installed on the vehicle's windshield to communicate with microwave antennas in the ETC lanes at toll stations. It employs computer networking technology to settle transactions with banks in the background, allowing vehicles to pay highway or bridge tolls without stopping. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass through toll stations without stopping; Cost-saving: Reduces wear and tear and fuel consumption by minimizing vehicle starts and stops, and users can enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC systems faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

Why does the car suddenly lose fuel supply during normal driving?

Sudden loss of fuel supply during normal driving may be caused by excessive carbon deposits. Related solutions are as follows: 1. Check the fuel tank pump: Verify if it's functioning properly. The fuel pump motor makes noise when working. If the pump fails to supply fuel normally, it will cause insufficient vehicle power. 2. Inspect the fuel filter: Check for leaks or blockages. If the leak worsens, simply starting the vehicle could potentially ignite it due to static electricity. 3. Examine the intake pipe: Look for dirt blockages. Remove the air filter to check for water ingress, and replace the air filter if necessary. 4. Check the valve timing: Ensure the valve timing is correct and that the intake/exhaust pipes are tightly sealed. You can clean the throttle body or add a cleaning-type fuel additive (fuel system cleaner) to the gasoline, which can achieve certain carbon removal effects.

Should I buy the Audi A3 with 1.4T or 2.0T?

The choice should be based on the owner's needs; opt for the 2.0T if more power is required. Below is a relevant introduction to the Audi A3 1.4T and 2.0T: 1. Engine Introduction: The Audi A3 primarily features a 1.4T turbocharged engine, with an additional 2.0T turbocharged engine available, both paired with a 7-speed dual-clutch transmission. In terms of the chassis, the Audi A3 adopts a front MacPherson strut and rear multi-link setup. 2. Power Performance: The 35TFSI model is equipped with the high-power version of the EA211 1.4T turbocharged engine, delivering a maximum power of 110kW (150PS) and a maximum torque of 250N·m, which remains highly competitive today. The 40TFSI model, on the other hand, utilizes the EA888 third-generation 2.0T engine with a fuel hybrid injection system, boasting a maximum horsepower of 140kW (190PS) and a torque of up to 320N·m, providing ample power. The transmission is still paired with the 7-speed S-tronic dual-clutch gearbox, which has been time-tested in Volkswagen and Audi models, excelling in both performance and reliability.

Is C1 much harder than C2?

Compared to C1, C2 is much easier to learn because automatic transmission vehicles do not have a clutch, eliminating the need for frequent clutch pressing and gear shifting. Simply using the brake and accelerator to control the speed is sufficient. C1 Driver's License Test: The test subjects include four items: traffic regulations and related knowledge, field driving, road driving, and safe and civilized driving common sense. Passing standards: Traffic regulations and related knowledge (Subject 1) — Written test, full score of 100, passing requires 90 or above. Field driving (Subject 2) — On-site, actual vehicle. The minimum requirement is 80 points, below 80 is a fail. Road driving (Subject 3) — Highway or simulated field, actual vehicle. Full score of 100, must achieve 90 or above to pass. Safe and civilized driving common sense — Written test, questions mainly in the form of cases, pictures, animations, etc., question types include true/false, single-choice, and multiple-choice, totaling 50 questions, full score of 100, passing requires 90 points.

Can Windshield Washer Fluids Be Mixed?

Occasional mixing is acceptable. Different windshield washer fluids have varying ingredient ratios, and mixing them may produce impurities that could clog the nozzles. However, occasional mixing generally doesn't cause significant issues. Below is relevant information about windshield washer fluids: 1. Main components: Deionized water, alcohol, ethylene/propylene glycol, methyl ether, protective agents, surfactants, dyes, etc. 2. Functions: Capability to clean stains without leaving water marks; dustproof and antistatic properties make surfaces less prone to dirt accumulation after cleaning; antifreeze properties; corrosion resistance that won't damage glass or vehicles; winter-specific formulas additionally provide antifreeze and antifog capabilities. 3. When mixing is acceptable: Purified water can be added during summer or warm weather; emergency situations may warrant occasional mixing of different fluids; same-brand antifreeze washer fluid can be mixed with summer formula. 4. When mixing should be avoided: Avoid randomly mixing different brands; winter formulas in northern regions should preferably not be mixed; never substitute water for washer fluid in winter; if fluids must be mixed under special circumstances, remember to drain the mixture at night, especially in cold weather.

What to Do When a Diesel Engine Won't Start Due to Cold Weather?

Six solutions for a car that won't start in cold weather: 1. When the battery power is insufficient and the vehicle cannot start: You can find a car with a fully charged battery, park the two cars front to front, and use jumper cables to borrow power from the other car's battery to start your vehicle. 2. For older vehicles that are difficult to start: Try pressing the accelerator while turning the key, as this can help the vehicle start to some extent. 3. Automatic transmission vehicles should be in P (Park) mode: Check if the gear is in P mode for automatic transmission vehicles. If not, the vehicle cannot be started. 4. Use the preheating system to start the engine: Diesel vehicles in winter need to utilize the preheating system to start the engine. Turn the key to the power-on position and wait for the preheating light on the dashboard to go out before the car can be used normally. 5. Push-start the vehicle: Have a companion push the car from behind while you turn the key to attempt starting. 6. Pour hot water on the vehicle's oil pan: Use hot water to raise the engine temperature, increasing the fluidity of the oil to help the vehicle start more easily.
