What are the reasons for the keyless start failure of the BAIC EU5?
4 Answers
There are many possible reasons, such as system issues, wiring problems, or battery faults. The specific cause can be diagnosed at a 4S shop. Below is relevant information about the BAIC Group: 1. Introduction: Beijing Automotive Group Co., Ltd. (referred to as "BAIC Group") is a key enterprise in China's automotive industry. Established in 1958 and headquartered in Beijing, it has grown into a large state-owned automotive enterprise group covering R&D and manufacturing of complete vehicles and components, automotive service trade, comprehensive mobility services, finance and investment, etc. It ranked 134th in the 2020 Fortune Global 500. 2. Structure: BAIC Group owns well-known enterprises and R&D institutions such as BAIC Motor, BAIC Off-Road Vehicle, Changhe Automobile, BAIC New Energy, BAIC Foton, Beijing Hyundai, and Beijing Benz.
I encountered a keyless start failure with the BAIC EU5, which might be caused by multiple issues. The most common one is a depleted key fob battery—try replacing it with a new one, and that usually solves the problem. Another possibility is insufficient vehicle battery power, where the current isn't strong enough during startup, causing the system to fail. Dirt or interference between the key fob and the car's module, such as parking near high-voltage power lines disrupting signals, can also be the culprit. Occasionally, software glitches may occur, requiring an update or reset. I remember one time when it wouldn't start in cold weather—it turned out the sensor was frozen, but it worked fine after warming up. My advice is to first check the key fob's position (don't place it too far away) and test the battery voltage. If the issue persists, visit a 4S店 immediately to avoid compromising travel safety. Additionally, parking away from interference sources and regularly maintaining the key fob battery and car battery can prevent many headaches.
The keyless start malfunction in the BAIC EU5 might stem from electronic system issues. Possible causes include: faulty internal circuitry in the key fob (aged chip or short circuit) preventing signal transmission to the vehicle's receiver; worn or dusty contact points on the start button leading to unresponsiveness; interrupted CAN bus communication due to outdated software causing bugs; or strong interference from nearby devices like phones disrupting signal transmission. From experience, first troubleshoot basic issues: test the key's functionality at different positions, replace its battery to check results, then use diagnostic tools to scan for error codes and identify the root cause. Avoid forcing operation during malfunctions as it may damage the vehicle—instead, promptly visit professional repair shops. They can efficiently address circuit module issues or perform system resets to prevent escalation affecting driving controls. Regular maintenance to keep the vehicle's interior and exterior clean also helps minimize dust accumulation on electronic components.
My BAIC EU5 has experienced keyless start issues, which are quite annoying. The main reasons are the key battery being depleted—replacing it with a new one can solve the problem; or the vehicle battery voltage being too low, causing it to stall upon startup; occasional software errors leading to sluggish system responses. Once, it wouldn't start on a rainy day, and I found the induction area was corroded due to water ingress—it worked fine after drying. It's recommended to pull over immediately and turn on hazard lights for help; avoid attempting repairs yourself to prevent further damage. Regularly checking battery health and updating software can prevent such failures.
