In order to turn off car alarms, crime is taking many methods. Detailed information about all these techniques (or most of the techniques) helps when choosing and installing security systems, as well as for additional organization of car protection from theft.
Instructions
Step 1
With a properly installed high quality dual rolling code alarm, it is impossible to open the vehicle without triggering it. Therefore, hooligans resort to hacking the car, counting on the owner's inattention and the indifference of witnesses. But most alarm models have errors and assumptions. Knowing the installation method and alarm model helps to disable it by exploiting design weaknesses. You can find out the model by the labels of the manufacturers or services, as well as by the standard operating modes of the LED.
Step 2
If there is not enough information and the alarm cannot be turned off, repeated attempts to find the weak point are used. Persistence in this matter is determined by whether the car is ordered or not.
Step 3
It is often used as a way of convincing the owner that the system has gone bad. In this case, the alarm can be triggered for no reason visible to the owner of the car. The actions of the hijacker are aimed at convincing the owner of the need to turn off the alarm. This is done by throwing a rubber ball into the body or firing a pneumatic gun at the wheels.
Step 4
Therefore, when the alarm is triggered, take a close look: are there any strange personalities nearby. Do not turn off the alarm in any case and check it for serviceability in the near future. Move the car to the guarded parking lot. Remember that the car thieves are constantly watching you, and your demonstration of a strong desire to save the car may induce the car thief to abandon his plans.
Step 5
Don't over-count on signaling capabilities. It only helps to protect the car from theft, regardless of its cost. Always pay attention to all of its triggers.
Step 6
Consider methods to protect the weaknesses of the alarm. To turn it off, hijackers often turn off the power to the system, knowing that it comes from the battery and is taken in the car. Having got to the bottom of the car, they cut the wire going to the passenger compartment from the generator and de-energize the alarm. Car alarm, not provided with autonomous power supply, ceases to function.
Step 7
In addition, hijackers often disable the system's common power supply fuse by short-circuiting the turn signal during an alarm. They muffle the siren, damaging it or filling it with quickly hardening foam, if it is poorly hidden. The stun gun is discharged onto the car body or onto the turn signal wire, thereby disabling or disarming the alarm.
Step 8
On many car models, the installation of the alarm requires that the system wiring is accessible from outside the car. In this case, the hijackers simply cut the required wire to turn off the system. The code of the key fob that controls the alarm is selected (scanned) by the computer, if the anti-theft system is not equipped with an anti-scanner.
Step 9
They also intercept the code with a grabber code, record it and then play it back to disarm the security mode if the alarm does not have a dynamic code. The dynamic code is decoded and, knowing the algorithm for its construction, the next code is predicted. Double dynamic code helps against this.
