The door lock cable is malfunctioning, replace the door lock cable. The central locking system is activated, unlock the central lock button before attempting to open the door. If the remote key cannot open the door, temporarily use the mechanical key to open the door.

There are quite a few reasons why a car door won't open. Having driven for over a decade, I've encountered many situations. First, in winter, the lock cylinder can freeze. You can slowly pour warm water along the door edge to thaw it, but avoid splashing hot water on the glass to prevent cracking. Second, the remote key fob might be out of battery or have signal failure. Simply replace the battery or use the spare physical key to turn the lock cylinder. Third, the child safety lock might be engaged, preventing the rear door from opening from the outside. You'll need to enter from the driver's seat to turn off that small switch button. Fourth, the door handle could be worn out or the internal cable detached. Gently jiggle the door or get it repaired—don't force it open and damage the seals. Fifth, an electronic system failure, such as a bug in the door control module. Try disconnecting the battery for a few minutes and reconnecting it. If that doesn't work, have a technician inspect it. Preventive maintenance is key: regularly clean the lock mechanism to ensure driving safety. Never take reckless actions that could harm people or the car.

How many kilometers should a car run before replacing brake pads?

It depends on the car's mileage. Generally, they should be replaced every 50,000 kilometers. Here are methods to check if a car's brake pads need replacement: 1. Thickness - A new brake pad is typically about 1.5cm thick. With continuous friction during use, the thickness gradually wears down. Professional technicians recommend that when visual inspection shows the brake pad thickness has reduced to about 1/3 of the original (approximately 0.5cm), the owner should increase self-inspection frequency and prepare for replacement. 2. Listen for sounds - If a metallic scraping sound (like "iron rubbing iron") accompanies light braking, the brake pads must be replaced immediately. This indicates the wear indicators on both sides of the brake pads are directly contacting the brake disc, proving the pads have exceeded their limit. In such cases, the brake disc should also be inspected during replacement, as this sound often means the disc is already damaged. Simply replacing the pads may not eliminate the noise, and severe cases may require disc replacement. 3. Feel the braking force - As pads thin, braking efficiency decreases. You'll need to press the pedal deeper to achieve the same braking effect that previously required light pressure. When the initial braking response weakens noticeably (many drivers describe this as "soft brakes" or reduced stopping power), it's time to check if the pads need replacement.

What to Do When the Gear Exclamation Mark Appears on the Dashboard?

Dashboard gear exclamation mark is the transmission system warning light. TCU, which stands for Transmission Control Unit, refers to the automatic transmission control unit. This function enables automatic transmission control, making driving simpler. The appearance of this symbol indicates an abnormality in the transmission. If this light comes on while driving, you should stop driving immediately and seek professional assistance at a 4S shop as soon as possible. Generally, only cars equipped with automatic transmissions have this light. Cars with manual transmissions do not have this light because manual transmissions lack computers and sensors, making them less prone to malfunctions.

What Causes the Oil Warning Light to Illuminate When the Engine Overheats?

Engine oil warning light illumination during engine overheating is caused by excessively high engine temperature, insufficient oil level, sensor malfunctions, and other factors. Below is the classification of automotive engine types: Classification by Fuel Type: Internal combustion engines can be categorized into gasoline engines and diesel engines based on the fuel used. An internal combustion engine using gasoline as fuel is called a gasoline engine, while one using diesel is called a diesel engine. Gasoline and diesel engines each have distinct characteristics: gasoline engines feature higher rotational speeds, lighter weight, lower noise levels, easier starting, and lower manufacturing costs; diesel engines have higher compression ratios, greater thermal efficiency, and better fuel economy and emission performance compared to gasoline engines. Classification by Cooling Method: Internal combustion engines can be divided into water-cooled engines and air-cooled engines based on their cooling methods. Water-cooled engines utilize circulating coolant within the cylinder block and cylinder head water jackets as the cooling medium, whereas air-cooled engines use air flowing between the cooling fins on the outer surfaces of the cylinder block and cylinder head as the cooling medium. Water-cooled engines provide uniform cooling, reliable operation, and effective cooling performance, making them widely used in modern automotive engines.

Can I Still Take the Test After Failing Subject 2 Five Times?

You cannot retake the test after failing Subject 2 five times. Here are the precautions for taking Subject 2: 1. Reverse Parking: The main points for deduction in reverse parking include pressing the line while reversing, the car not entering the parking space, exceeding the time limit, and not following the prescribed route. Reverse parking must be completed within 210 seconds; exceeding the time limit results in failure, and not following the sequence also leads to failure. Pay attention to the 30cm margin when reversing. 2. Parallel Parking: The main points for deduction in parallel parking involve the turn signal, the 30cm margin, and pressing the line. 3. Right-angle Turn: The main points for deduction in the right-angle turn are the turn signal and pressing the line. Operating the turn signal incorrectly after entering the test area deducts 10 points.

What are the reasons for a battery not charging?

The reasons for a battery not charging include: dried-up electrolyte in the battery, broken plates, short-circuited plates, etc. The most common reason is plate sulfation, which hinders the normal flow of electrons, leading to a decrease in battery capacity, inability to function properly, and gradual aging. In this case, the battery needs to be replaced. The method for removing the battery is as follows: 1. The battery is located in the engine compartment. First, open the compartment and locate the battery. 2. Remove the battery terminal protective cover and the nuts on the fixed bracket. 3. First disconnect the negative terminal, then remove the positive terminal. The negative terminal is disconnected first to avoid short circuits, as it is connected to the vehicle body. 4. After removing all the fixing screws on the battery, the old battery can be taken out.
