The method to deactivate the anti-theft system on the Besturn B50 is: Open the car trunk, lock all doors, insert and remove the car key more than 6 times. At this point, the ID stored in the remote control will be cleared. Then, use the inner door handle to manually lock the driver's side door, press the lock button once more, and then open the driver's side door. The car's anti-theft system will then be deactivated. The Besturn B50 is a car independently developed by FAW Car, with dimensions of 4615mm in length, 1785mm in width, and 1435mm in height, and a wheelbase of 2675mm. The car has optimized vibration and noise control, with improvements in pass-by noise and steady-speed driving vibration noise, enhancing the quietness of the interior space.
I've encountered the anti-theft lockout issue with my Besturn B50 several times and would like to share some reliable solutions. The most straightforward method is pressing the unlock button on the original remote key - you'll hear a 'beep' indicating the system is deactivated. If the remote doesn't respond, try inserting the mechanical key into the driver's side lock cylinder and turning it twice; opening the door this way will automatically disable the anti-theft system. Another emergency solution is to open the hood, disconnect the negative battery terminal, wait for half a minute, then reconnect it - this essentially reboots the vehicle. If none of these work, there might be an anti-theft module malfunction requiring OBD diagnostic tool for reprogramming. Once my car got locked in a mall basement, and the 4S store technicians resolved it within five minutes using their diagnostic computer. Remember to avoid randomly pressing the key buttons as it may accidentally trigger the anti-theft system.
Fixed quite a few Besturn B50 anti-theft system malfunctions, mainly resolved in three steps. First, confirm if it's a false trigger - sometimes the key fob battery running low causes random alarms, and simply replacing the battery might solve it. If it's genuinely locked, using the mechanical key to open the driver's door is the most reliable method. Wait three seconds after opening until the engine immobilizer light goes off, then you can start the car. For stubborn cases, check the fuse box under the steering wheel - a blown 7.5A anti-theft fuse can also cause locking. Last time a customer's car locked after DIY battery replacement, I taught them to press and hold the emergency release button at the lower left of the steering wheel for five seconds to fix it. As a last resort, connect a diagnostic tool to clear fault codes - this job is best left to professional repair shops as randomly disconnecting wires may damage the control module.
My car had an anti-theft lockout issue last month. For the BYD B50, resolving it isn't actually difficult. Use the mechanical key to open the door and get in, but don't rush to start the engine. Insert the key, turn it to the ON position, and wait for three minutes. If the anti-theft light on the dashboard goes off, it's back to normal. If that doesn't work, try simultaneously pressing the unlock and lock buttons on the key for 10 seconds to force a reset. The electronic anti-theft system is prone to short circuits due to moisture, especially during the rainy season when such problems often occur. Last time my car locked out after a heavy rain, disconnecting the battery for half an hour and reconnecting it did the trick. If these methods don't work, then consider the possibility of a faulty anti-theft module, and you'll need to visit a repair shop to match the key chip.
