Do you know the car lock jammer?
Recently, have you seen such news that children are locked in the car because of the high temperatures which resulted in death. Yes, under the hot summer sun, if the child is locked in the car, the temperature inside the car will rise quickly If the door can not be opened in time, the child's life will be very dangerous. If you've installed a car lock GPS jammer, don't worry. Here we will introduce the car lock jammer to you.
To understand the working principle of the car lock jammer, we must first understand the principle of the car key lock. Most of the car keys in the market now have a built-in microchip: when you use the key to control the car remotely, the microchip and the key car will exchange signals by the low frequency code of each car. There is a unique car decoder which, when it receives the remote control signal, decodes it into a sequence of letters and numbers, considered as a unique identifier and sent to the car computer's identification system. Corresponds to the identification code saved in the computer memory.When the car correctly decodes the signal of the electronic chip inserted in the car key, the car will proceed to the designation of the car key, for example by starting the car key. car, by locking it or opening the door. Actually, there are many ways to encrypt and decode car signals, mainly fixed code chip and rolling code chip types of encryption, as well as two-way dynamic code encryption. Here, it is not necessary to know too much about the type of on-chip encryption, the jammer mainly interferes with the frequency used by the signal sent by the key of the remote control, thus realizing the disturbance function of the lock.
The main function of the car lock blocker is to interfere with the lock using the key, if you install the car lock jammer near the car, you can not play any role in locking the key from the key. car to lock the car. Its working principle is to emit wireless signals with the same frequency as the car.The frequency range used by the low frequency signals emitted by the electronic chip in the car key is certain.The main operation depends on the lower frequency at 125 kHz, and the jammer chip will come out. A signal of the same frequency is output, so that the decoder inside the car receives the signal of the remote control car from the car key, without the car being able to be locked.
And the use of the car jammer is very simple, just install the jammer with the interference lock function close to the target car, to make sure the power of a jammer is normal. If you choose portable jammer, make sure fully charged before use, the continuous working time is less than two hours. If you choose a desktop jammer, make sure the jammer is turned on, then turn on the switch.
