What is the reason for the constant flashing of the red lock icon on the Changan Eado?

The flashing lock icon on the Changan Eado indicates that the anti-theft system is active. Below is an introduction to the car's anti-theft system: 1. Definition: The car anti-theft system is designed to prevent the theft of the vehicle itself or items inside it. 2. Main function: It prevents unauthorized use of the car's own power to steal the vehicle, specifically preventing illegal engine start-up. 3. Importance and components: The vehicle anti-theft system and the engine immobilizer system are essential for ensuring vehicle security. The anti-theft system consists of an electronically controlled remote or key, electronic control circuits, alarm devices, and actuators.
I also encountered this flashing red lock symbol issue when driving my Changan Eado. At first, I thought it was an anti-theft system malfunction, but later learned it's normal for the anti-theft indicator light to flash after locking. If it keeps flashing after starting the engine, you should check the door lock status or signal receiver. From my experience, low remote key battery is the most likely culprit - try replacing the coin cell yourself first. If that doesn't work, inspect whether the door switches are stuck or deformed. If it flashes while driving, be cautious as it might indicate an anti-theft module problem - visit a 4S shop immediately to read the fault codes. DIY repairs for such electronic issues could make things worse. Remember to check the battery voltage too, as the anti-theft system can act up when the battery is low.
Last time I helped a friend deal with the flashing red lock light on the Yidong. First, you need to distinguish the timing: if it flashes after turning off the engine and locking the doors, it's just the anti-theft system in standby mode—no need to worry. But if it flashes while trying to start the car, it’s likely a key recognition issue. The most common cause is a weak key battery. I’ve opened it up and measured with a multimeter—if the voltage drops below 2.8V, replace it. Also, don’t overlook mechanical issues: an improperly closed trunk lid or water-shorted door sensors can trigger false alarms. In special environments like near high-voltage power stations, interference can cause flashing—just drive 300 meters away to reset. If the cause remains unclear, try the spare key to rule out damage to the primary one.
I've studied the flashing red lock symbol on the Changan Eado. Essentially, it's the anti-theft system sending signals. Regular flashing after locking indicates the vehicle has entered alert mode, similar to a computer's breathing light in sleep mode. There are two abnormal scenarios: rapid flashing during startup indicates system authentication failure, most likely due to weak key fob chip signal; sudden flashing while driving is absolutely abnormal and requires immediate inspection of circuit fuses. For DIY solutions, first reset the system by disconnecting the negative battery terminal for five minutes before reconnecting - this essentially reboots the vehicle's computer. Here's a handy trick: press the key fob against the start button when starting to enhance signal transmission range, which serves as a temporary solution for low key fob battery.
