Why Can't the Wuling Hongguang Mini's Doors Lock?
3 Answers
It is highly likely due to a malfunctioning remote lock or aging of the car's remote transmitter antenna, among other factors. Below is an introduction to the Wuling Hongguang Mini: Configuration: The Wuling Hongguang Mini's electric motor has a maximum power of 20kw and a maximum torque of 85 Nm. This car uses lithium-ion batteries across all models, which are stronger and have higher energy density. The front suspension of the Wuling Hongguang Mini uses a MacPherson independent suspension, while the rear suspension uses a multi-link non-independent suspension. Dimensions: The Wuling Hongguang Mini has a wheelbase of 1940mm, with length, width, and height dimensions of 2917mm, 1493mm, and 1621mm respectively. This is a 3-door, 4-seater car, with a curb weight of approximately 700 kg.
My Hongguang Mini also had frequent issues with not locking properly before, and I later found it was mainly due to several common problems. The door not being shut tightly is the most frequent occurrence – sometimes a gentle push seems to close it, but it’s still slightly ajar, especially the rear door, which needs a firm push to fully latch. Another common issue is a dead remote key fob battery, which typically needs replacement every year or two; just open the key cover and replace it with a CR2032 battery. Interference from nearby transformers or signal towers can also cause problems, but driving the car a few meters away usually resolves it. If the door lock mechanism is jammed with dust or malfunctions, the door panel may need to be removed for servicing, especially in older cars. Additionally, check the car battery – when it’s low on charge, the central locking system won’t respond at all. After locking manually with the mechanical key, it’s best to measure the battery voltage. Lastly, it could be a blown fuse or wiring issue; if you can’t fix it yourself, take it to a repair shop to read the fault codes with a diagnostic tool.
Having repaired many Hongguang Mini cases, the first step is to check if all four doors and the tailgate are fully closed. The remote key has a high failure rate—observe the key's indicator light when pressing the button; if it doesn't light up, the battery is dead or the key is faulty. Parking near high-power electrical devices can cause signal interference, so try moving to a different spot. Door lock mechanisms can rust and stick due to rainwater ingress, and freezing in winter can also cause jamming—applying some rust remover or lubricant can help. If the central locking module is faulty, check the circuit voltage, usually located under the driver's side door panel. Another possibility is incorrect wiring from an aftermarket alarm system causing conflicts. Poor internal contact in the driver's door lock switch can also affect the entire vehicle, requiring disassembly to clean the contacts. If none of these checks resolve the issue, it's recommended to take the vehicle to a workshop for BCM (Body Control Module) diagnostics.
