Is the warning light still on when the car remote control key is locked after being disturbed?

Methods to prevent interference of automobile remote control signals;

First, pull the door handle after locking the car to check:

The actual measurement shows that the interference is indeed inevitable, but it is not helpless. In fact, in addition to paying attention to some anti-theft details according to the characteristics of the original car, it can also be solved by upgrading the anti-theft system of your car.

Now we know that when the wireless jammer works continuously, it will block the communication between the owner's remote controller and the host computer and prevent the vehicle from receiving the instructions from the remote controller. So pay attention to some details when locking the car every day. When locking the car by pressing the lock key of the remote control, the most effective way is to press the remote control lock and then pull the door handle by hand to see if it is locked. And when you press the lock button, pay attention to the fact that the lights of the original car will flash synchronously. If there was a jammer working at that time, the light would not blink after pressing the remote control.

Second, the security system upgrade is safer:

In addition, you can choose to upgrade the anti-theft system. At present, the most popular car anti-theft systems are RFID keyless system and GPS anti-theft system with wireless network.

Keyless system brings a brand-new comfortable and convenient experience to users: the owner only needs to carry the remote control with him during the whole driving process, without using the key to open the door and drive. When the owner enters the effective range, the car will automatically detect the key and identify the identity, and can open the door with a light hand. This seemingly insignificant change has substantially improved the safety of vehicles. Because its remote control key and the car can be authenticated in both directions, when the door is closed, the host will automatically send a signal to the remote control. As long as the host does not receive the response from the remote controller, it means that the remote controller is no longer in the car. Interference When the communication between the remote controller and the host is blocked, the host will not receive the response from the remote controller, and the door will naturally be locked.

Another is to install an upgraded anti-theft system with GPS and wireless network, which is the latest high-tech product. It is connected with the ECU of the automobile through CANBUS and adopts the special design of the automobile. In case the car door is unlocked after the owner leaves, it will send a text message to the owner's mobile phone through the mobile network.

Of course, car owners need to be reminded to distinguish between true and false when upgrading the anti-theft system. Some manufacturers of burglar alarms claim that their products can avoid interference. In fact, according to industry experts, most similar products change their frequencies to non-3 15 or 433. If their frequencies are made public, they will be affected by jammers.
