Changan car key has four buttons with the functions of locking, unlocking, opening the trunk, and one-touch window control. Below is relevant information about the Changan car key: 1. Introduction: The Changan car key is relatively simple, equipped with an electronic remote key that also includes a hidden mechanical key for use when the remote key runs out of power. 2. Working Principle: The key emits a weak radio wave, 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 locking or unlocking action. The remote key does not require locating the keyhole and can conveniently lock and unlock the car from a distance. This system mainly consists of two parts: the transmitter and the receiver.

What are the reasons why the trunk cannot be opened?

The reasons why the trunk cannot be opened: 1. Linkage rod or lock cylinder problem. If you often use the key to open the trunk lid, it means the linkage rod is broken and needs to be repaired at a repair shop; 2. If you always use the remote control to open the trunk lid, it means the lock cylinder is dirty or rusty. Spray a rust remover into the lock cylinder a few times to open it; 3. Mechanical part failure or problems with the trunk itself, such as a broken trunk wire or other trunk-related issues causing the car trunk to fail to open; 4. Generally, five-door cars cannot be opened from the inside. For example, some hardcore off-road vehicles do not have a trunk switch to prevent accidental activation during driving, which could cause injuries, so the trunk can only be opened from the outside.
