4S stores can configure new metal keys for car owners by querying the anti-theft password for key configuration in the database based on the vehicle license and the owner's ID card provided. After the car key matching is completed, the new key will be activated, and the lost key will become invalid immediately. Even if someone picks up the old key, they can only open the car door mechanically.

Yes, car keys can definitely be re-made, and it depends on the type of key. For example, simple mechanical keys can be handled by street key stalls or 4S shops, usually costing just a few dozen yuan, which is quite convenient. However, if it's a remote key with a chip, professional equipment is required for programming; otherwise, the car won't recognize it and won't start. In this case, it's more reliable to go to a 4S shop or a professional auto service shop, and the cost may exceed a hundred yuan. I recommend bringing your vehicle documents to prove ownership when you lose a key to prevent security risks. It's wise to keep a spare key handy in daily life, so you can act quickly in case of loss and avoid delays.

What gear should an automatic car be in when parked with the AC on?

Put it in P gear. The following is a related introduction to the gears of an automatic car: 1. R gear: The reverse gear of an automatic car. After shifting into R gear, the car will generate backward traction, which is used for reversing into parking spaces and parallel parking. 2. N gear: The neutral gear of an automatic car. Unlike manual cars, it does not completely disconnect the transmission from the engine and can only be used briefly when waiting at traffic lights. 3. D gear: The drive gear of an automatic car. Simply shift into D gear, press the accelerator to speed up, and press the brake to slow down to drive the vehicle. 4. S gear: The sport gear of an automatic car. It allows the car to unleash stronger power and acceleration, and is used on highways and in congested road sections. 5. L gear: The low gear of an automatic car, also known as the climbing gear. It can reduce the car's speed to ensure the engine delivers powerful force, often used on bumpy roads or when climbing long slopes to provide sufficient power.

What should be considered when buying car insurance?

When purchasing car insurance, the following points should be noted: 1. Pay attention to the choice of purchasing channels. 2. Carefully select insurance products based on your actual needs and fully understand the terms and conditions of motor vehicle insurance. 3. Be mindful of the use and safekeeping of important insurance documents, fulfill the obligation of truthful disclosure, pay insurance premiums on time, and agree with the insurance company on dispute resolution methods. Below is an expanded classification of car insurance: 1. Generally, four major types of insurance are required: compulsory traffic insurance, third-party liability insurance, third-party non-deductible coverage, and vehicle damage insurance. 2. Compulsory traffic insurance is mandatory for every car owner as per national regulations. 3. Third-party liability insurance covers the remaining compensation amount when compulsory insurance falls short in compensating others. 4. Non-deductible coverage and vehicle damage insurance: Non-deductible coverage is an additional insurance that covers the remaining 20% when the combined compensation from compulsory insurance and third-party liability insurance only reaches 80%. 5. Vehicle damage insurance ensures coverage for vehicle repairs in case of malfunctions.

What to Do When Your Car Key Battery Dies and How to Start the Car?

If your car key battery is dead, simply replace the battery. The method and precautions for battery replacement are as follows: Method to Replace the Key Battery: Gently press the small switch on the back of the key to remove the mechanical key. You can then use the mechanical key to open the key cover by inserting it into the slot next to the key and gently prying it open. Remove the key compartment cover, and you will see the position of the old battery. It is recommended to use a small flat-head screwdriver to more easily remove the old battery. Ensure the new battery is placed with the positive side facing up. Reinstall the key cover and mechanical key, and confirm that the key functions properly. Precautions for Battery Replacement: Do not use the wrong battery. The battery life of a smart car key is approximately one year. Battery consumption varies depending on how frequently the key is used. Using the key at different distances will also affect the amount of power consumed. Be very cautious when replacing the battery of a smart car key, as any mistake could damage the circuit board inside the key.

Why is the car door handle not retracting smoothly?

It may be due to an improperly positioned cable clip or significant friction between the vehicle's door handle lock and the lock post, causing the handle to not retract smoothly when opening or closing the door. Here are some explanations regarding car door handle retraction issues: 1. Improper positioning: The solution for an improperly positioned cable clip is to use a T-20 spline to remove the small cover of the door handle, open the door, locate the small hole on the door edge, and loosen the inner screw with the T-20 spline (be careful not to remove it completely). This allows the small cover of the door handle to be manually adjusted. 2. Excessive friction: The solution for excessive friction is to apply a screw loosening agent to lubricate the door lock post. Lightly spray some screw loosening agent on the post and also apply some to the door lock area to achieve a lubricating effect.

Why doesn't Volkswagen use CVT transmissions?

Volkswagen has dual-clutch transmissions, and many of its models are equipped with small-displacement turbocharged engines, which are more suitable for pairing with dual-clutch transmissions. Below are specific introductions to different types of transmissions: CVT: CVT is a continuously variable transmission. Its advantages include fuel efficiency, low maintenance costs, and smooth operation, but it has weaker acceleration thrust and limited capacity for high-torque engines. AT: AT is an automatic transmission. Its advantages include ease of operation and relaxed driving, as the automatic transmission selects the most suitable gear based on vehicle speed and feedback from the onboard computer. However, it has higher maintenance costs and fuel consumption. DCT, DSG: DCT and DSG are both dual-clutch transmissions. They offer fast gear shifts, high efficiency, and low fuel consumption. However, they require high production precision, resulting in higher costs, and provide less comfort.

Difference Between Mercedes-Benz with 4MATIC and Without

If a Mercedes-Benz has '4MATIC' at the rear, it indicates that the vehicle is equipped with a four-wheel drive system. Generally, models like the Mercedes-Benz GLC, GLE, or other SUVs come standard with a four-wheel drive system, while some sedans typically feature a rear-wheel drive system. Below is an introduction to 4MATIC: 1. Origin: 4MATIC is Mercedes-Benz's proprietary four-wheel drive technology, introduced in 1987. Similar to Audi's quattro and BMW's xDrive, 4MATIC enhances vehicle stability at high speeds through four-wheel drive, significantly improving safety. 2. Function: 4MATIC can achieve differential limitation via the ABS braking force distribution function. When a wheel slips, the onboard computer uses ABS to brake the slipping wheel, preventing it from spinning freely. Thus, the 4MATIC system allows the vehicle to take corners at higher speeds, improving handling limits to some extent. 3. Features: Compared to other four-wheel drive systems, 4MATIC is lighter in weight. A Mercedes-Benz equipped with 4MATIC is only about 70kg heavier than its rear-wheel-drive counterpart, resulting in better fuel economy.
