Emergency opening of cars

Face the problem of lost or stolen car keys account for the majority of motorists. Someone actually lose, somebody lost the keys, but sometimes it happens that the keys are inside the cabin, and the owner outside and without duplicates. On such occasions there is an emergency car opening. Learn how to master running on opening what immobilizer and how it is made possible in this photo essay:




So. We have a car brand Toyota with lost keys.



And we have a master who is so accustomed to such stories that do not even listen to them until the end. "Everything is clear, show the document to the machine," - said, as cut off.



As in the history of the apartment, the master checks before starting work on the car documents. Status and rights of cars should be on hand, or slamming of car interior.



Then the master of the castle looks, Sherudilo in his toolbox and just a minute reveals the car. Since I have here is not a textbook for bugbears and hijackers, but that's going to show this photo.



The machine opened, but it is only half the battle.



Again and again in the search box desired instrument



Another 10 minutes and the lock removed.



Also lock Removing the immobilizer. Now the main work will be done with it



We leave the workshop.



Workpieces such case, hundreds, if not thousands. The company's specialists "Our Master" argue that the lack of calls and do not sit idle. So that the stock is justified



Workplace



A huge pile of unknown circuits, soldering iron, loop, and much more. He looks at me, smiles and says that all this must be every day



And now the most interesting. What is the immobilizer?
Most modern cars have regular immobilizer installed automaker. In normal lock immobilizer is made without the help of a relay. The device physically and software associated with a controller of fuel injection engine, so the absence of the enable signal, the controller itself will not initiate startup and maintain operation of the engine. In other words, the block is not physically, but by the system software of the engine control.
The principle of a separate (optional, freelance) immobilizer is tearing the connection of electrical circuits in the most significant areas - for example, the starter circuits, ignition engine. With this car will be guaranteed on-site parking, even when penetration into the attackers. When using additional devices (eg solenoid valves) can lock operation of non-electric systems.
On and off the immobilizer should be available only to the owner of the car. As a rule, for this purpose uses an electronic key code. Less common model with manual dial code. Before you start the car, the owner has to insert the code key in a special slot, thus ensuring the immobilizer code reading system and unlock or place an electronic "tag" (chip) in the area of ​​the antenna of the immobilizer system. In systems with manual dial the code to turn off the immobilizer must enter the code set by the owner.
With the destruction of the immobilizer or unauthorized trip, vehicle systems remain locked.
Almost all types of immobilizers have auto-arming after a certain period, during which do not produce any action the owner.



Standard immobilizer consists of two main parts:
 - The control unit, which is the center from which receives signals about the need to revitalize the entire system (I had pokazyal)
 - Key, which is the owner of the car and that is recognized by the control unit.



Immobilizers come in different sizes, but all are tiny by themselves



To your computer and connect the unit immobilayshera read information. There are two ways - to fill in the new code immobilizer and then the old keys will not fit, and you can leave the old. Experts recommend changing codes.



Then insert the capsule in the blank and go to the second machine



Master in opening transmits maker of circuit lock for making a new key



On this machine we introduce a fixed workpiece and drawing



Voila - the key ready
