Specific reasons for the car not responding when pressing the car key are as follows: 1. Nearby interference. Car remote keys transmit signals via radio waves, which are then received by the car's receiver to execute corresponding actions. Facilities such as high-voltage power towers, radio base stations, or even thunderstorms and heavy fog can interfere with radio waves, causing the car key to be unresponsive despite having power. 2. Building obstruction. Radio waves have a certain penetration capability, allowing remote operation even through a wall or building. However, as the battery power decreases, the strength of the radio waves is affected. While normal face-to-face operation may work, the waves may fail to penetrate buildings. 3. Low battery power. As mentioned above, as the battery power decreases, the range and strength of the radio waves diminish. For example, at full charge, remote operation might work from 100 meters away, but with half the battery left, the operational distance might reduce to only 50 meters. If you operate the key from 50 meters away, you might only see the indicator light on the key but no response from the car. 4. Loss of remote key password. Exposing the key to strong magnetic fields or high temperatures can cause the remote key password to be lost, resulting in the car key being unresponsive despite having power. In this case, you need to visit a 4S shop or a professional car key store to re-match the remote key. 5. Faulty remote key circuit board. A faulty remote key circuit board exhibits symptoms similar to a lost password, but the difference is that the remote key can no longer be re-matched and must be replaced. At a 4S shop, replacing the key involves using a blank remote key sent by the manufacturer and matching it with your car.
