However, this wireless remote control function is not valid anywhere, so let's find out together. What pits can cause the car key to fail!
1. Restaurant concentration area interference level: ★★★★★
Many restaurants are equipped with a mobile device to order food for the convenience of the guests. They are ordering machines. However, if the restaurant's ordering machine is used, the frequencies of the frequency bands used for the three non-faulty products and the range of the car's remote control key will make it easy to overlap. However, after leaving the area, the remote control key will return to normal.
2. Anti-theft alarm interference level:: ★ ★ ★ ★
If a burglar alarm malfunctions, the frequency of the emitted radio wave band will be very wide, which will also affect the remote control key.
3. Electric retractable door Interference level index: ★★★★
Nowadays, with the convenience that automation brings to people, in many places we can also see products under automation everywhere, such as electric retractable doors installed in residential areas and unit gates. When the remote control operates retractable doors, it will continue to issue specific frequency bands. Radio waves.
4. Electronic screen concentration area interference level: ★ ★ ★ ★
If an open large electronic screen fails, the resulting source of interference will disable the remote control key.
5. Substation, high-voltage interference level: ★ ★ ★
Substations or high-voltage lines are subject to strict technical restrictions and generally do not exceed the standard for radio wave radiation. Unless a specific fault occurs, it will create signal interference.
Editor's Note: When driving out of the car, be sure to pay attention to the parking environment. When the car is locked, check if the car has any reaction. After the car is locked, it is the most effective method. If there are suspicious persons around, don’t hurry to leave. .
