Here are the causes and solutions for car remote key failure: 1. The key battery is dead. First, observe whether the key's indicator light is functioning normally. It's necessary to check the key battery. If it's confirmed to be dead, simply replace the key battery. 2. External interference, such as being under high-voltage lines or near an airport. The signal frequency sent by the key is interfered with or disrupted. Generally, this issue can be resolved by leaving the special location. No repair is needed. 3. The key itself is damaged. In this case, check that the key battery is functioning normally. There is no external signal interference. Simply use another key. 4. There is a problem with the vehicle's electrical system. For example, the control unit of the anti-theft system is damaged. There is an issue with the wiring, etc. It is necessary to drive the vehicle to a repair facility for further inspection and measurement using diagnostic equipment and professional instruments to determine the cause of the fault.
