What is the reason why the trunk button of Roewe 550 cannot unlock?
2 Answers
Roewe 550 trunk cannot be opened may be caused by switch failure, key failure, etc. The following is relevant information: 1. Normal opening method: Normally, the trunk can be opened by pressing the open button on the remote key for more than 2 seconds to open the trunk, and the interior lighting of the trunk will turn on. Then directly press the release button above the license plate on the trunk to open it. 2. Precautions: If the trunk cannot be opened, the Roewe 550 trunk has a safety escape device, which adopts a pull-ring design. You can pry open the pull handle with your hand and pull the trunk emergency release cable to open the trunk from inside. The operation is very simple, but the owner should familiarize themselves with the location of the safety escape device in advance.
As a seasoned driver with over 20 years of experience, I've encountered numerous cases where the Roewe 550 trunk button fails to open. The most common issue is dirt or damage to the button itself, where accumulated rainwater or dust causes contact short circuits or oxidation. In winter, plastic components become brittle due to cold contraction, preventing the button from springing back properly. Another frequent cause is a blown fuse. The Roewe 550's fuse box is located below the driver's seat on the left side, with the trunk lock fuse labeled 'Tailgate'—a 15-amp fuse that's prone to blowing, especially during circuit overloads. Wire aging is also a significant problem, as the wiring harness at the rear of the car is susceptible to wear and tear at the hinge points, leading to open circuits or short circuits. If the button doesn't respond when pressed, first use the key to manually unlock and check if the button is stuck. It's advisable to clean the button regularly, avoiding water jets, and pay extra attention to protection during the rainy season. If the problem persists, it's recommended to visit a professional shop for a circuit inspection.
