Car anti-theft alarm is a multi-functional product, not only can be anti-theft, but also can remote start boot, remote control switch door, remote control switch window, remote start engine, remote locking engine.
The use of car burglar alarm systems is based on the use of car power supplies and some of the car's own circuits. Once an alarm is detected, it will affect the normal use of the vehicle. What are the causes of these common failures? How to deal with? The author here sorts out the cause of the failure and gives everyone a few tips.
Symptom 1: A function key of the remote controller fails, and the LED indicator does not light when the key is pressed.
Analysis of reason: Failure of a function key (other function keys are normal) is mostly due to the damage of the function key or the soldering of the solder joints between the key pins and the circuit board. The keys of the remote controller are mostly micro-switches, and the intensity of use is usually light, and attention is paid. Waterproof, drop and heavy pressure.
Symptom 2: The remote control distance becomes shorter and shorter. When the signal is transmitted, the brightness of the LED of the remote controller becomes dark or flickering.
Analysis of reasons: This phenomenon is mostly battery power shortage, replace the battery. In addition to this, it is recommended not to adjust or replace the remote control components by themselves, so as to avoid further losses.
Symptom 3: The remote control operation does not work. When the remote control function keys are pressed, the red LED of the remote control does not light.
Analysis of reason: This fault is more in the remote control itself, there are the following situations:
1. The battery is exhausted. 2. The battery is positive and negative. The reed is rusty or is in poor contact. 3. The remote controller is exposed to rain or water, oil, etc. In this regard, the circuit board can be taken out, washed with industrial alcohol, dried with a household hair dryer or until it is naturally dried.
