What are the methods for car anti-theft?

[DeJuniper]

Here are the methods for car anti-theft: 1. After parking and removing the key, turn the steering wheel until you hear a click (steering wheel locked). 2. Install an anti-theft device and ask the technician to adjust the vibration sensitivity higher, so that it will alarm at the slightest vibration. 3. After parking, you can shift into reverse or first gear to prevent the car from being pushed. 4. Install a steering wheel lock bar. Below is an introduction to anti-theft devices: 1. Mechanical anti-theft devices: including hook locks, steering wheel locks, and gearshift locks, which mainly rely on locking the clutch, brake, throttle, steering wheel, or gearshift to achieve anti-theft purposes, but they only prevent theft without alarm. 2. Electronic anti-theft devices: including card-type, button-type, and remote-control types, which mainly rely on locking the ignition or start to achieve anti-theft purposes, while also having anti-theft and sound alarm functions. 3. Network anti-theft devices: including the Global Positioning System (GPS) and the Car Anti-theft Device (GQF), which silently transmit alarm information and the location of the alarmed vehicle to the alarm center.
