Why can't the Sagitar car key unlock the car door?

[NoahMarie]

Here are the reasons why the Sagitar car key cannot unlock the car door: 1. The remote key has no power: The remote key uses a button battery, which may not be available in convenience stores. If there are auto parts stores or 4S shops nearby, these places will definitely sell them. Usually, car owners can buy more online for emergency use. 2. The remote key is interfered by signals: The situation where the key signal is interfered is relatively rare. When it is ensured that the key battery has power, and the following situations occur, it can be judged as signal interference. 3. The connection device between the door handle and the door lock itself is faulty: The car door cannot be opened due to this situation, which belongs to the fault type, and the possibility of the car owner solving it by himself is very small. Because the door connection mechanism may fall off due to driving bumps, the door lock cannot sense the action of pulling the door handle.
