The reason for the flashing anti-theft lock on the Great Wall Fengjun 5 may be: the vehicle is equipped with an engine electronic anti-theft system, and it cannot be started without a chip key. In this case, you need to call a tow truck and can only go to a 4S store for processing. More information about the anti-theft lock is as follows: 1. The principle of the anti-theft system: A general car anti-theft system has an integrated chip with some switch gates. When an external trigger voltage is applied, the switch gates open and output a positive voltage to the drive circuit, inferring the actuator and alarm circuit. 2. Radio remote control: It is an important component of the anti-theft system and is a remote control device that uses radio signals to control various mechanisms at a distance. After these signals are received by the remote receiving device, they can instruct or drive other corresponding mechanical or electronic devices to perform various operations, such as closing circuits, moving handles, starting motors, and then these mechanical devices perform the required operations.
I was quite panicked when I first encountered this situation, but later I found out that the flashing anti-theft light on the Fengjun 5 is mostly a minor issue. The most common cause is a dead battery in the remote key—when the car can't detect the signal, it activates the anti-theft mode. Another possibility is that a door isn't properly closed, especially the tailgate, as the sensor's position is higher up and prone to misjudgment. Last week, after my car got wet in the rain, the light started flashing, and I discovered it was due to poor contact from water ingress in the front passenger door lock. Sudden power loss or the installation of a GPS tracker might also cause the anti-theft system to malfunction and lock. Never randomly pull out fuses—first, try pressing the unlock button on the original car key a few times, and if that doesn’t work, replace the battery. The most troublesome issue is a faulty body control module, which requires a diagnostic tool to read the error codes for confirmation.
