What is the reason why the trunk button of Roewe 550 cannot unlock?
2 Answers
Roewe 550 trunk may not open due to switch failure, key malfunction, etc. Normally, the trunk can be opened by pressing and holding the unlock button on the remote key for more than 2 seconds, which will also turn on the interior trunk light. Then, directly press the release button above the license plate on the trunk to open it. Common reasons why the trunk cannot open are as follows: 1. Linkage rod or lock cylinder problem: If you often use the key to open the trunk, the linkage rod may be broken, and you should go to a repair shop to fix it. If you always use the remote control to open the trunk, the lock cylinder may be rusty. Spray rust remover into the lock cylinder several times to unlock it. 2. Not unlocked: The trunk is difficult to open if it is not unlocked with the remote key. Before opening, it is best to press the unlock button on the key or check if the key battery is dead.
Last time I encountered an issue with the trunk release button on my Roewe 550 not working. I tinkered with it for quite a while. The button itself is prone to malfunction—over time, the contacts can wear out or get clogged with dust, causing it to become unresponsive. A simple cleaning or replacement of the button usually does the trick. Short circuits in the wiring or blown fuses are also common, especially fuse F15 in the fuse box, which tends to blow if water gets in during heavy rain. Checking and replacing it is inexpensive. If the locking mechanism is stuck, spraying some lubricant into the latch and jiggling it a few times might free it up. A glitch in the central control system could also cause signal errors—try disconnecting the battery's negative terminal for five minutes and then reconnecting it to reset the system. If none of these solutions work, don’t force the trunk open. Head straight to the 4S shop to check the fault codes—safety first. Regular maintenance to inspect the button and wiring connections for rust can prevent future issues and avoid breakdowns on the road.
