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 them? A few days ago, the experts analyzed the causes of the failure and provided support for everyone.
Symptom 1: 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 up.
Analysis of reasons: This fault is mostly in the remote control itself, and there are the following situations: (1) The battery is exhausted; (2) The battery is positive or negative, and the reed is rusty or in poor contact; (3) The remote controller is rained or Water, oil, etc. In this regard, the circuit board can be removed, cleaned with industrial alcohol, dried with a household hair dryer or allowed to dry naturally before use.
Symptom 2: The remote control distance becomes shorter and shorter. When the signal is transmitted, the LED brightness of the remote controller becomes dark or flickering.
Analysis of the reasons: This phenomenon is mostly battery power, replace the battery. In addition to this, it is recommended not to adjust or replace the components of the remote control yourself to avoid causing greater losses.
Symptom 3: A function key of the remote controller fails. When this key is pressed, the LED indicator does not light.
Analysis of the reason: The failure of a function key (other function keys are normal) is mainly because the function keys are damaged or the soldering points of the key pins and the circuit board are detached. The keys of the remote control are mostly micro-switches, which are usually light when used, and they are waterproof, drop-proof, and heavy.
