What are the reasons for the Roewe 550 key not responding when starting?

[DelWeston]

Roewe 550 key not responding when starting is caused by: 1. Insufficient battery power; 2. The gear is not shifted to P or N position; 3. Poor contact of the starter signal wire; 4. Failure of the start-stop switch. The body dimensions of the Roewe 550 are: length 4625mm, width 1827mm, height 1480mm, and wheelbase 2705mm. The Roewe 550 is equipped with the TST 6-speed oil-cooled dual-clutch automatic transmission system, Inkanet 3G digital intelligent network driving system, Start-Stop digital intelligent start-stop energy-saving system, EPB digital intelligent electronic parking system, and Configurable color-customizable digital instrument system.

I've been driving a Roewe 550 for several years and have encountered the embarrassing situation where the key wouldn't start the car. That time was in winter—turning the key in the morning got no response at all, not even the dashboard lit up, which made me sweat with anxiety. I checked the key; the remote could still unlock the doors, and the battery was newly replaced, so it shouldn’t have been an issue. Later, it occurred to me that the car battery might be low on charge. Using a multimeter, I measured the voltage—it was just over 10V, too low to start the engine. I connected a jump starter, and it fired up right away, saving the day. A friend at the repair shop told me that Roewe's electronic systems are sensitive; if the key chip ages or the anti-theft system is triggered, it could lock the ignition, requiring a trip to the dealership to unlock it. For routine maintenance, I’ve developed the habit of checking the battery monthly, keeping a charger in the trunk, and during winter, making sure to drive longer distances after short trips to keep the battery charged—prevention is better than cure.

As a newbie driving a Roewe 550, I was completely stunned when the car wouldn't start at all last time. The remote key could unlock the doors, but the ignition just wouldn't work, and I was worried the car might be broken. After searching online, forums suggested that a dead battery is a common cause; I tried turning on the lights and they were dim, so I quickly called for rescue to jump-start the car. The rescue guy taught me to first check the key battery—try replacing it; then test the battery voltage—if it's below 12V, jump-start it; or check if the gear is in P and if the doors are properly closed. He also mentioned the anti-theft system might have falsely locked, which for Roewe requires professional handling. This experience taught me a lesson—now I regularly maintain and check the battery, and keep some emergency tools handy to avoid panic.

Having worked in the repair shop for a long time, I often encounter Roewe 550 startup failures. Mostly it's due to a depleted battery—if the voltage is below 12V, it won't start. Weak key fob batteries also need replacement and inspection. Next, check the main fuse; if the starter fuse in the engine compartment fuse box is blown, there will be no response at all. Then examine the gear position sensor—Roewe has indicator lights for this—or if the key chip doesn't match the anti-theft system, an OBD scanner is needed to read and reset the fault codes. Simple steps: first replace the key fob battery, then test the battery; if that doesn't work, scan the codes and repair the relay. I advise owners to address the issue early to avoid small problems becoming expensive major repairs.
