What is the reason why the trunk button of Roewe 550 cannot unlock?

[DelBrooklyn]

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.

As a veteran driver with ten years of experience driving the Roewe 550, I've seen plenty of cases where the trunk button won't open. Usually, the main culprits are button wear or loose wiring. Lift up the rear seats and check if any wire connectors have come loose—just plug them back in tightly. If a fuse has blown, you'll find it in the engine compartment fuse box; locate the one corresponding to the trunk and try replacing it. Weak remote control battery signals can also be the issue—swapping in a fresh battery might do the trick. If the lock mechanism is stuck, try manually pulling the trunk's internal emergency release switch as a temporary fix. Humid weather can cause button corrosion due to water ingress, so regularly clean dust and keep it dry. If all else fails, head to a repair shop—avoid DIY disassembly to prevent making things worse and wasting time.

I think the trunk button of the Roewe 550 is malfunctioning, and electrical circuit issues are likely the key. Poor internal contact in the button switch can be checked by testing the resistance value with a multimeter—replace if abnormal. Checking and replacing a blown fuse at the F15 position is simple. For a short circuit, perform a continuity test to locate and repair the break. The relay is in the control box; swap it with an identical model to test functionality. If the central control signal reception is faulty or there's a software bug, a power reset might help. Finally, use a diagnostic tool to read the fault code and pinpoint the issue for repair. Regular circuit inspections can reduce risks.

It's quite frustrating when the trunk button of my Roewe 550 doesn't work while using it with my family. Common issues include button failure or loose plugs. First, try using the remote unlock—if that works, the button is likely faulty and replacing it is straightforward. Check for aged or broken wiring with exposed copper causing short circuits; feel the wires for any heat or stiffness. A blown fuse, often due to overload, just needs replacement—don't overlook this. If the lock is jammed with dirt, spray lubricant or clean the slot for looseness. It's advisable to keep the trunk tidy to prevent objects from jamming the door. If problems arise, avoid forcing it open; seek a professional mechanic for safe and efficient handling to prevent accidents.

Analysis of Roewe 550 trunk button unlocking failure reveals multiple systemic issues. The button has the highest damage rate due to a design prone to water accumulation and dust ingress, requiring replacement. Fuse F15 overloads and blows—check its position in the box and reinstall. Wiring wears and breaks at bends—test continuity and repair connections. The lock actuator motor may jam or fail—apply lubrication or replace. ECU software errors can be resolved by disconnecting power for a few minutes to reset. Check vehicle voltage stability, replace parts, and test step by step for troubleshooting. Regular maintenance of trunk sealing is recommended to prevent moisture and extend lifespan.
