Why does the Chery A3 door lock always make automatic noises?
2 Answers
The main reasons for the Chery A3 door lock making noises are the following two situations: 1. The lock spring of the door lock may be damaged, causing the door to fail to lock properly when closing or locking. A relatively effective solution is to first hold the door handle, then use the mechanical key to lock it, turn the key, and then release the door handle. 2. The latch of the door lock is damaged, so even if the door is locked, there is still a gap. It is necessary to repair the door latch and lock spring; otherwise, it will affect the comfort of the car and the safety of the door not closing properly.
As a veteran driver with over a decade of experience driving Chery cars, the constant self-triggering door lock noise is indeed annoying, usually caused by aging mechanical parts getting stuck. For example, the spring in the latch may have weakened or rusted, causing the door to rattle and trigger noise with even a slight breeze. Additionally, worn or deformed door seals can prevent the door from closing tightly, leading the sensor to misinterpret the lock status repeatedly. When I drove in northern regions during harsh winters, the metal contraction exacerbated this issue. I recommend checking if the lock cylinder moves smoothly and applying some lubricant. If that doesn’t work, you’ll need to replace the entire lock assembly—it’s not expensive, but it’s best done at an authorized repair shop. Also, be mindful during car washes to avoid splashing mud or water into the lock mechanism to minimize such noise troubles.
