Reasons for the Roewe 550 key not responding when starting: 1. Dead battery; 2. Ignition switch failure; 3. Poor contact. The Roewe 550 is a 4-door, 5-seater sedan under SAIC Roewe, with body dimensions of 4648mm in length, 1827mm in width, and 1483mm in height, and a wheelbase of 2705mm. The front and rear tire specifications are 215/55R16. The car is equipped with a 1.8-liter naturally aspirated engine, delivering a maximum power of 98 kW and a maximum torque of 170 Nm, featuring a MacPherson independent front suspension and a multi-link independent rear suspension.
I often encounter this issue with my Roewe 550. When I turn the key, there's no response—it's mostly due to a weak key battery. A new key battery costs just a few bucks to replace. Try using the spare key to confirm the problem. If the car's main battery is old and lacks charge, the dashboard lights will dim or flicker. If the voltage drops below 12V, you'll need a jump-start or battery replacement. Check the fuse box, located under the driver's side or in the engine compartment. The F2-labeled starter fuse is prone to blowing—test its continuity with a multimeter yourself. Occasionally, the anti-theft system misreads the key signal; try unlocking and attempting again. If all else fails, visit a repair shop to inspect the ignition switch or relay circuit—don't force the key and risk damaging the system. Regular maintenance can prevent hassles, especially in cold weather when battery issues are more common. Stay calm and troubleshoot step by step.
