Welcome to our shop! Introducing our brand new Anti-theft Device with dual function selection to prevent theft and robbery. This device is small in size, making it easy to install and highly concealable. It is compatible with vehicles that already have burglar alarms installed. The sensing distance of this device can be freely adjusted, making it suitable for any 12V car. When the vehicle does not detect any induction, the car cannot be started after opening the door. Additionally, if the vehicle is running and no induction is detected, the vehicle will automatically turn off and cannot be started again. In case of emergencies, there is an emergency release mode that allows you to choose car wash or maintenance mode. The device also features a buzzer that will prompt you if the internal battery voltage of the proximity card is too low. With a 2.4GHz frequency, this device experiences less interference and is power-saving. The proximity card uses a large capacity CR2032 battery, which is built-in.
