Why does the BMW 5 Series remote control sometimes work and sometimes not?
1 Answers
BMW 5 Series remote control sometimes working and sometimes not may be caused by a dead key fob battery, surrounding interference sources, or a faulty body control module. Dead key fob battery: When the key fob cannot transmit signals, it may cause malfunction. The solution is to replace the key fob battery and test drive to check if the issue persists. Surrounding interference sources: Interference sources around the vehicle may disrupt signals transmitted by the key fob or received by the antenna. The solution is to remove all aftermarket devices inside the car and then test drive. Faulty body control module: If the vehicle antenna or body control module is faulty, causing the antenna to fail to receive signals or the body control module to fail to recognize signals, the key fob's lock/unlock function may be affected. The solution is to visit a professional repair facility for inspection and maintenance.
