At the beginning of the new year, the annual college entrance examination is coming. Recently, some car owners and 4S shop staff received some strange news that mobile phone signal jammers will be used near the examination room, which will seriously affect the vehicle data signal, causing the car door to malfunction or be unable to open. The solution to this situation is to use a mechanical device key to manually unlock the car door.<\/p>\n\n\n\n

This situation occurs in consideration of the “emergency” that may occur during the college entrance examination. For example, there have been cases where candidates have violated regulations and used high-tech equipment to cheat. Therefore, almost all examination rooms now have cell phone jammers<\/a> installed around or even inside the examination room. These signal blocking devices are effective in preventing cheating, but they also cause signal interference to nearby vehicles driving or parked, causing the smart key to malfunction.<\/p>\n\n\n\n

Why does the key fail? To understand this problem, we need to master the characteristics of the mobile phone signal jammer<\/a> used in the examination room.<\/p>\n\n\n\n

    \n
  1. The jammer can block all frequencies from 20 to 6000MHz, and the frequency can be flexibly adjusted to avoid the frequency of police equipment inspection.<\/li>\n\n\n\n
  2. The examination room jammer is equipped with a dedicated drive power generation device and an automatic control system, which does not occupy indoor space, does not emit organic waste gas and noise, and reserves the back seat.<\/li>\n\n\n\n
  3. The roof antenna is equipped with an electric tilt mechanism, which can be adjusted quickly and can be mixed with VIP or leadership transport teams. The speed can reach 100 km\/h to prevent remote control time bombs from detonating. When not in use, the antenna can be lowered for concealment or other tasks.<\/li>\n\n\n\n
  4. The modular plug-in design facilitates the later adjustment of the mobile phone signal jammer frequency band and output power, and is more convenient for maintenance and repair.<\/li>\n\n\n\n
  5. The examination room jammer is equipped with a DDS control module, which can directly adjust the power and frequency band through the mobile phone software, and a dedicated communication frequency band can be set in an emergency.<\/li>\n<\/ol>\n\n\n\n

    From the above characteristics, it can be seen that the examination room mobile phone signal jammer can continuously block all frequencies between 20-6000MHz, and this frequency range also covers the frequency used by the car remote control key, so when the examination room jammer is started, the car remote control key will also be affected. The best-selling wifi jammers<\/a> and GPS jammers<\/a> in recent years.<\/p>\n\n\n\n

    However, there is no need to worry about this problem. If the smart car key is affected and fails or does not respond, please use the mechanical device key to unlock the car door, bring the remote control key close to the one-button start switch (make sure it is close to the running sensor), and then lightly step on the brake pedal as usual to start the engine, and the car can start normally.<\/p>\n\n\n\n

    Please note that the vehicle’s positioning system may experience delays and the recorder may experience temporary loss of station reception. However, rest assured that these issues will resolve once the car is moved away from the electromagnetic interference.<\/p>\n\n\n\n
