Tips: Don't let the anti-theft device protect yourself from the four major situations

Introduction: Now the anti-theft device is almost universal to every car, and the phenomenon of anti-theft device failure from time to time has become a worry for many car owners. I don't know if you have encountered such a situation. When you encounter thunder and rain, the anti-theft device is too sensitive, and the tweets all night left the neighbors unhappy, or once the malfunctioning door cannot be opened, even the engine cannot be started. Of course, it is impossible to waste food because of choking, and this anti-theft device must still be installed. But when the anti-theft device fails, the owner should also learn a few tricks, there is a response, lest the anti-theft device protect himself. The following shows a few faults and solutions of the failure of anti-theft devices:

Problem 1: The battery voltage is low, affecting the anti-theft removal

Phenomenon: When the anti-theft device sends a release signal, the host cannot respond normally, the door cannot be opened, or the car cannot be started.

Reason: In many cases, the anti-theft device cannot be released because the current voltage of the battery cannot reach the starting voltage of the anti-theft device.

Solution: Check and replace the battery. Check whether the pile head of the battery is loose, corroded, and whether the battery water is lost. Prepare a set of battery cables in the car for emergency self-help.

Problem two: static interference, code skipping and garbled characters on the remote control board

Phenomenon: The remote control board placed in the pocket is easily broken by the static electricity generated by friction, causing garbled characters, so that the anti-theft cannot be lifted.

Reason: At present, most of the anti-theft devices on the market are out of order code skip configuration. The remote control board of this type of anti-theft device is most afraid of electrostatic interference.

Solution: Place the remote control board of the anti-theft device in your handbag to avoid static electricity that interferes with the remote control due to friction. Prepare a battery to prevent the trouble caused by the sudden power failure of the remote control board.

Question 3: The central control lock is frozen and the door cannot be opened

Phenomenon: After the car is parked outdoors overnight, the central control lock may be frozen, resulting in the phenomenon that the door still cannot be opened after the anti-theft is lifted.

Reason: The sealing performance of some domestic vehicles is poor. As the service life increases, the sealing tape gradually ages. After rain, snow or car washing, the water infiltrated by the bar at the door will flow to the central control lock.

Solution: When installing the central control lock, a technician is required to wrap the lock with plastic film to prevent water from entering in the future. In fact, as long as there is a door that can be opened, it will not affect the road. After the temperature rises, the central control lock will resume function.

Question four: emergency

When the anti-theft device fails, if the owner of the vehicle cannot accurately determine where the problem originated at that time, the connection of the plug-in plate of the anti-theft device can be directly removed to temporarily solve the problem. In response to the weather changes, when an anti-theft device starts to sound when there is a wind and grass, the sensor of the anti-theft device can be removed. This method can reduce the sensitivity and reduce the "wolf is coming" situation. However, the entire vehicle can still be in a state of alert, and there will be warnings if the door is opened illegally.

Since the previous anti-theft device uses fixed code technology, there are certain deficiencies in function, and a newest technology of rolling code anti-theft device is available on the Chengdu market. Compared with the original fixed code technology, this anti-theft device makes the car owner more convenient to operate, and it has three advantages: it can also match the code when it is not visible; it can be remotely controlled remotely; it is made by pure software to prevent copying. Take advantage. At present, there are two well-known brands of rolling code anti-theft devices, including cheetah and police lion, with prices ranging from 700 yuan to 1,000 yuan.
