For some, it is still unshakable, like a "poker" on the steering wheel - as useless as tenacious. Others, on the contrary, developed a complex of doom - they rely either on insurance compensation, or simply on luck. One thing unites both those and others - complete indifference to the technical nuances of protection.

At one time (ЗР, 2003, No. 11) we talked about some non-standard methods of work of installers of security and anti-theft systems. But, unfortunately, on the whole, the “anti-theft empire” still looks rather miserable - the perfection of technology and technology is shattered to the degree of reluctance, and the inability of many “specialists” to be creative in their work. Screw the siren to the most visible place and install a relay next to it, breaking some kind of power wire - that’s all their “protection”! It's a shame that branded auto centers often sin with such hack work - is it any wonder that even super-expensive satellite systems with this approach turn into an ordinary hook on a rotten gate? Pull harder - and come in.

But you can act differently. We won’t draw specific electrical circuits - the technical level of crooks is already very high, but we will be happy to share some of the tricks of our work with all “Zarulevtsi”.

Electronic lock

Image

To begin with, you can block the gearbox! This is not about mechanical locks, namely electronics: after all, many new cars (especially expensive ones) are equipped with automatic transmissions with solenoid valves! They allow you to achieve an interesting effect: the engine starts as usual, and the car does not go: the blocked valve does not create the necessary pressure! The drawback is one, moreover, of a psychological nature: as a rule, clients boldly allow the master to delve into the most complicated motor electronics, but are very worried about the safety of the box. By the way, the starter also causes a similar reverence for them - they say, disassemble at least half of the machine, but do not get in here! Therefore, more often than not, we continue to dance around engine control systems.

We have long ago refused to lock the power circuits - we prefer to work with sensors. This does not require the use of power control elements, and such protection is more difficult to calculate. However, if earlier it was enough to break the signal from the same crankshaft position sensor (DPKV) in a couple of places, now we adhere to the “new faith”. Old tricks can no longer be dispensed with: a thief has grown wiser and does not go to business without a scanner. And he famously reports the absence of the DPKV - he has to be deceived. To do this, instead of the standard sensor, we connect its double, and for completeness we do the same with his colleague - the camshaft position sensor DPRV. Fuss, of course, more, but good work requires it.

Electromechanical relays are dismissed: in addition to low reliability and large dimensions, they still have the bad habit of clicking loudly - in some cases, the hijacker can take advantage of this. Optron switches are much more reliable, and their small size allows you to hide them directly in the bowels of regular harnesses. I note that the invisibility of the installation, which is absolutely necessary for dialogue with the hijacker, has another value in our time: owners of warranty cars often fear conflicts with the branded service. It's no secret that any attempt by the owner to do something on the side is perceived there with hostility - they say, we will remove it from the guarantee and all that. Therefore, once again teasing the geese is also useless: there is no evidence of extraneous interference - there is no reason for conflict. However, from my own experience I know that not a single car that I visited was removed from the guarantee. So it should be: any lawyer will say that such actions by servicemen require irrefutable evidence of a causal relationship between a car breakdown and any preliminary intervention in its design.

The basic rule of the installer is to think and act outside the box. Where a conveyor belt arises, the client begins to count the money thrown away - this is a shame for the master.

LAUNCHING A SATELLITE

How much satellite systems cost and how they get around them is well known. However, if the client really wants this kind of toy - why not? Moreover, you can create something like this with little blood: after all, mobile phones are sold today on every corner.

The idea has long been on the surface - we do not claim authorship, but we cannot do without know-how. So, we fantasize: a suitable mobile phone is taken, a little finalized and connected via a special adapter to the security alarm. It remains for the customer to install their SIM-card and … and, in fact, that's it! Now you will find out about every attempt on your car almost immediately - the car will call itself! You can expand the scope of the toy: use the search system, which has leading mobile operators, for example, "MTS-Search". In this case, the results of the search for a mobile phone - and with it the car - can be displayed on an electronic map of the city. It goes without saying that you can use similar technology not only when hijacking a car, but also for other purposes - for example, determining where a friend went in your car. In general, there are many options.

AND IF SERIOUSLY

But seriously, we are always talking about painstaking fuss with each machine. We are refining not only the car, but also the signaling units that we use - we remove the elements that are unnecessary, in our opinion, from there and do something else. In addition to increasing reliability, this also affects safety: even if we assume that a bad master gets to the main unit on some super service and replaces it by slipping another key fob of the same company to the client, then this whole farm will not work.
