What is the method to turn off a car alarm?

The method to turn off a car alarm is: 1. Locate the wiring distribution of the anti-theft system under the steering wheel and inside the protective panel below the A-pillar; 2. Disconnect the input wire of the alarm. The functions of a car alarm are: 1. Utilizing the mobile communication network to activate the anti-theft function when the vehicle enters the locked state; 2. When an external force strikes the vehicle or the sensor detects vibrations within the alarm range, the alarm will sound. The working principle of a car alarm is: When the car is hit, impacted, or moved, the sensor sends a signal to the controller indicating the vibration intensity. Based on the vibration intensity, the controller will emit a warning sound or trigger a full alarm.
The alarm on my old car went off randomly last week, which really freaked me out at the time. It took several attempts before I figured out that I needed to press and hold the unlock button on the remote key for three seconds, and the alarm would stop with a beep. If the car key runs out of battery, don't panic—just use the mechanical key to turn the door lock, and when you hear two beeps, it means the alarm has stopped. A friend who owns a repair shop also taught me a trick: if the alarm malfunctions, open the hood, disconnect the negative battery cable, wait about half a minute, and then reconnect it to reset the system. However, this method might reset your radio presets, so it's best used as an occasional emergency fix. Most importantly, don’t let the neighbors mistake it for a car theft—if the alarm is accidentally triggered, check immediately to make sure all doors and the trunk are properly closed.
