What to do when the Baojun 730 dashboard shows a lock and the car won't start?

When the Baojun 730 dashboard displays a lock symbol, it indicates the vehicle is in a security lock state, meaning the car is locked. Simply use the remote to unlock and open the car door to resolve this. Dashboard functions explained: 1. Battery Indicator: Shows the battery's working status. It illuminates when the ignition is turned on and turns off after engine start. If it doesn't light up or stays on continuously, immediately check the alternator and circuit. 2. Fuel Indicator: Alerts when fuel is low. When lit, it means fuel is nearly empty, with approximately 50 km of driving range remaining from activation until complete depletion. 3. Washer Fluid Indicator: Displays windshield washer fluid level. Lights up when fluid is low, reminding the owner to refill. The light turns off after replenishment. 4. Electronic Throttle Indicator: During vehicle self-check, the EPC light illuminates briefly then turns off. If it stays lit, this indicates a fault requiring prompt maintenance.

My Baojun 730 had this issue before too. The dashboard showed a lock icon and it wouldn't start, which really frustrated me. At first, I thought the key fob battery was dead, so I quickly replaced it with a new one, but that didn't work. Then I checked the car's fuse box to see if the anti-theft system fuse was blown - that often happens due to voltage fluctuations. I also tried using the spare key in the ignition to confirm recognition, making sure there were no interference sources like phones or metal objects near the key. If these simple methods don't work, I suggest contacting the nearest 4S store immediately. They can use diagnostic tools to read the fault codes and solve the problem - it might just need an anti-theft module reset. Don't waste time, or it'll delay your trip.

I understand your frustration when encountering a dashboard lock symbol preventing engine start. The Baojun 730's anti-theft system is designed to immobilize the engine as theft protection. The key contains a transponder chip - when battery weakens or signal interference occurs, the system displays the lock icon and refuses ignition. First, verify if the key fob battery is depleted; replacement often resolves this. If not, inspect the key slot for dirt affecting contact - cleaning or using a spare key usually works. When remote signal is weak, try pressing the door button with the key nearby. For persistent issues, professional diagnosis is recommended - scanning control unit data, resetting or updating the anti-theft module typically solves it.

The dashboard showing the lock not starting is mostly caused by a dead key fob battery, and a simple battery replacement will fix it. Having driven for years, I know that Baojun cars often have similar issues, so regular maintenance is key: check the key fob battery every six months and keep a spare key functional. Also, avoid storing the key in high-temperature environments to prevent chip aging. These small precautions prevent problems. If the issue persists after replacing the battery, it might be due to a blown fuse or a short circuit affecting the anti-theft function, requiring professional attention. Don’t panic—contact a repair shop for a quick fix.

How to solve the issue of the Baojun 730 dashboard lock symbol appearing and the car not starting? Step 1: Replace the key battery and try starting. Step 2: Ensure the key is within the sensing range and there are no interferences inside the car. Step 3: Check the fuse box and replace any anti-theft related fuses that are blown. If the above steps don't work, disconnect the car battery for a few minutes and then reconnect to try restarting the system. If none of these solutions work, the anti-theft control unit might be faulty and requires professional diagnosis and repair. I encountered this issue and fixed it myself, saving a lot of trouble.

The dashboard showing a lock icon and the inability to start the engine poses significant risks, which I have personally experienced. Safety first—avoid repeated attempts to start the car to prevent further damage to components. It's advisable to safely park the vehicle and call for a tow truck to take it to a 4S shop for inspection. Common causes include key chip failure or false alarms from the anti-theft system, and attempting DIY repairs might worsen the issue. Technicians can use diagnostic tools to read fault codes and accurately repair the anti-theft module. Using original equipment manufacturer (OEM) parts in daily use can help prevent such failures and ensure reliability.
