Generally, the sensing distance between a car key and the car is within 10-50 meters. The actual distance depends on factors such as interference from other electronic devices nearby and the battery level of the car remote key. Insufficient battery power can significantly affect the signal reception distance. Below are some related details: 1. Detail one: A remote key allows you to unlock and lock the car from a distance without inserting the key into the lock. Its biggest advantage is that, regardless of day or night, you don't need to locate the lock hole and can conveniently unlock or lock the car from a distance. 2. Detail two: The remote key emits a weak radio wave from the owner, which is received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and the system's actuator then performs the corresponding action.

Can the engine compartment be washed with a high-pressure gun?

Engine compartment can be washed with a high-pressure gun. Reasons why it can be washed with a high-pressure gun: The electrical component interfaces in the engine compartment are waterproofed and not afraid of water. Therefore, it is common practice in many places to directly rinse the engine compartment with a high-pressure water gun. This is routinely done in repair shops and 4S stores, and it will not damage the components in the engine compartment. Precautions for washing with a high-pressure gun: Avoid washing with water when the car is hot. Cleaning when the engine temperature is high may cause the engine to suddenly cool down, potentially leading to cylinder deformation or cracking in severe cases. Moreover, washing at high temperatures can produce a large amount of steam, which may affect the electrical circuits.
