After applying film to the Mazda3 Axela, the key may not be sensed due to interference from metallic film or water ingress into the sensor. Metallic film interference: Check if the glass film itself is causing interference. Some films contain metallic particles that can affect signal transmission. Water ingress into the sensor: Water may have entered the sensor during the film application process. Proper vehicle protection, especially waterproofing, is essential during film installation. If excessive water flows into the vehicle's dashboard, door panels, window switch components, etc., during cleaning and film application, it can lead to various unforeseen issues related to these parts. These situations should not be overlooked. Minor cases may resolve on their own after a few days, while more severe cases could damage vehicle components, causing unnecessary trouble.

How Long Can a Motorcycle Be Used After Repairing Cylinder Scoring?

If a motorcycle's cylinder scoring is repaired at a professional repair shop with high-quality replacement parts, it can normally be ridden for more than two years under proper usage conditions. The main causes of cylinder scoring in motorcycles are as follows: Insufficient Break-in: Cylinder scoring caused by high-speed riding during the initial insufficient break-in of the engine. Before the engine can operate freely, the mating surfaces must undergo initial break-in to remove protruding peaks, making the surfaces smooth and evenly distributing the load. Therefore, a new engine must undergo a certain degree of break-in after assembly. Additionally, during the initial 1,000–2,000 km of riding, users should avoid prolonged high-speed operation. Cylinder Scoring Caused by Piston Overheating: When the piston overheats, localized abnormal expansion occurs. Due to piston deformation, the piston ring may temporarily or even permanently seize in the piston ring groove, preventing the piston ring from functioning properly. In this situation, the edge of the piston ring comes into direct contact with the cylinder wall under extremely high unit pressure, causing friction. This not only causes the piston ring to lose its ability to seal combustion gases but also leads to cylinder scoring. Cylinder Scoring Caused by Incorrect Piston Ring Clearance: During engine operation, carbon deposits inevitably form in the combustion chamber. As carbon deposits gradually accumulate in the piston ring groove, they hinder the movement of the piston ring, applying abnormal pressure and causing the piston ring to directly rub against the cylinder wall, resulting in cylinder scoring.
