14.1.23. Protect the car

It is possible to complain as much as necessary about the authorities which are not accepting due measures to reduction of number of stolen cars, the laws insufficiently severely punishing modern конокрадов, and in general all and all. But, as they say, "god helps only to those who does not forget to help to itself". The one who has worked to equip the iron horse with a reasonable set anticreeping devices, as a rule, it does not lose.

To hijack the car, it is necessary to get inside. For this purpose there are only two ways: to break glass or to open the lock by means of a key, a master key or other adaptation. It is possible to go deep, of course, into technology of this business that in itself небезинтересно. But from us it is enough of that criminals own it in perfection. And what it can oppose?

It is possible, certainly. To go by a collector armored car – there glass you will not break even with the help "калашникова". You agree? It is possible to go on more simple way – to raise durability has flown down. For example, by means of special "reserving" films. With keys it is more difficult. It is possible to put the additional lock, but as practice shows, it is not too effective protection. However, if there is no possibility to prevent car opening it is necessary to learn at least about it is any alarm system works at door opening.

The following step which the car thief should make, – to start the engine. The main boundary of defence of the majority of antijoy ride devices available in the market here lies. And for immobilizers is the main task, and for alarm systems – auxiliary. Certainly, all blocking are surmountable. But remembering that absolute protection does not happen, we will try to create to the malefactor of probably more difficulties. And in this respect competently put immobilizer предпочительнее. Besides, for removal of blocking it is necessary to open a cowl. Therefore will not prevent to put on it the additional lock.

Pay attention: both an immobilizer, and alarm systems differ on level of protection and quantity of the basic and additional functions. Thus the price depends both on the first, and from the second circumstance. And dearness of system – at all a sign of high security properties. Probably, simply in it it is a lot of auxiliary functions.

The started engine and the car going in the necessary direction – not same. Last boundary of protection of the car is based on this postulate. It is made by every possible mechanical systems – the lock of a wheel, pedals, трансмиссионный the lock... If there are bases to be afraid that the car will be simply dragged off on a tow it is possible to apply блокатор.

Now we will pass to practice. Having looked advertising, it is easy to be convinced that antijoy ride devices are very various. It is necessary to estimate features of use of your car: what it marks, what its technical condition, where as well as with whom you usually go where leave the car regularly where occasionally where she spends the night etc. Depending on it it is necessary to estimate risk of stealing. After that you will precisely know, those are however great a victim which can be brought for the sake of safety of the car. Such knowledge very much is useful to you at переговарах with a fitter.

Certainly, the competent manager in firm-fitter противоуголнных systems should find out that it is required to you. Besides, nobody knows better it all features of systems available available and devices and anybody is better it cannot help to pick up to you "for a place" the necessary configuration and a complex of protective means. Therefore concern with a great attention everything that he to you tells, and adhere to common sense. Do not forget that the manager has also interests.

At times not skilled people тычут a finger in the most expensive systems, believing their the best. Then come with the request to disconnect function, then another... Eventually they have a question: for what плачены money? Do not overestimate the possibilities. If face anticreeping systems for the first time choose the most simple in management. What is "enraged сигналка" know? Is not present? Means, to you has carried with neighbours. More often the alarm system "goes mad" because of the wrong reference with it and inability to understand an abundance of the basic and additional functions. Also has put at all in stupidity of separate automobile owners. After all if the car rebels because of operation of anticreeping system it is very difficult to not skilled person to think that to what. That is why do not forget to take from a fitter the instruction of the user and be not lazy with it in hands a little to practise. In deserted, certainly, a place.

However, alarm systems rage not only because of maloperation. That is why the question on reliability is quite actual. In a greater degree reliability depends on a fitter. Here it is necessary to rely on its reputation and guarantee certificates. But serviceability of the car is not less important. So if wish to protect a second-hand car, in advance prepare for additional expenses on repair of locks, electric equipments...

We name the five most, in our opinion, "reliable alarm systems": Bosch, Clifford, Sirio 777 Mouse, Sicura, Prestige.

Absolute protection is impossible. After all as a last resort always it is possible to ship the automobile car in a body of the truck or to drag off it эвакуатором. But today stealings of cars is a business, and any business aspires to reduction of costs. Therefore the preference is given to the cars which are not complicating a life. So create to car thieves of difficulty.


In a Soviet period one of the most popular anticreeping means was "секретка" – hidden in a jungle подкапотного spaces or salon back streets the additional switch of ignition. During Post-Soviet times it was found out that this device is not alien also to the capital world. However, there over it have properly worked, therefore the device, called "immobilizer" has turned out.

The immobilizer main task – to break off one or the several vital for work of the car of electric chains and thus to prevent stealing. At use of additional devices, for example electromagnetic valves, blocking of work of not electric systems is possible also. The basic особеность an immobilizer consists that at its destruction or unapproved switching-off of system of the car remain blocked.

Anticreeping systems

Aspiration as it is possible to protect more reliably the car from stealing conducted to working out more and more difficult designs. So there were devices which more correctly to name anticreeping systems. One of them – "Vekta". In it the mainframe is executed not folding, all wires have one colour, and some of them – false. "Векта" allows to break off four chains, and in two to change polarity of wires.

"The cyborg" actively advanced on our market "Alarm-service", – system of higher level. In it the mainframe is connected to regular conducting of the car, and ruptures of the vital chains are carried out by special devices. The small sizes strongly complicate their search. Besides, "Cyborg" has the wide list of additional functions and is connected to a city paging network. It is possible to call by the car to phone and to order to be got. Or, on the contrary, to stop.

Alarm systems

Initially the idea consisted in informing the owner on attempt at its favourite.

Modern alarm systems far have left from primitive systems on "two buttons". Practically all of them have remote, from брелка, inclusion – by means of infra-red beams or radio-waves. In the latter case the code is applied double or floating, constantly changing. The block architecture is widely applied: the mainframe can work with a wide set of gauges, the exit can be connected to a regular signal of the car or a siren – usual or with the independent food, reacting to electricity switching-off. It is possible to manage and without noise if instead of a siren to connect a pager (do not confuse to a paging network, is other pager) which will begin to squeak in a pocket of the owner of the car at alarm system operation.

Are not deprived modern alarm systems and anticreeping functions. Even elementary of them blocks work at least one electric chain. Basic difference from immobilizers consists that at switching-off of a food of blocking, as a rule, are disconnected.

Modern people love every possible services. Well, unless it is bad, if the alarm system itself closes locks of doors? Today it is possible to consider this function standard.

Additional locks

Still about ten years ago in remote places it was possible to see not only the truck, but also quite respectable "Volga" with huge eyes sticking out of a door under hinged амбарный the lock.

Then the first in our market the devices blocking a steering wheel and pedals "have gone". Motorists with the experience well remember these massive железяки a horrible kind.

It is necessary to mention and "the Israeli miracle" – Mul-t-lok – the lock fixing the lever of a gear change. It is obvious that with "automatic machine" these devices protect the car better as the mechanical box allows to tow the car with the squeezed out coupling.

The following kind of the antijoy ride device – блокиратор wheels, a thunder-storm of infringers of rules of a parking.

And at last last design - the additional lock of a cowl. However, the in itself lock does not represent a barrier to the car thief. After all for start of the engine of the modern car it is not required to open a cowl, and furthermore – a luggage carrier. Therefore such locks are good only as the additional measure complicating access to the alarm system or an immobilizer.

Jackie against gop-stop

From all variety of functions one deserves the separate story. It is car protection at armed assault. Are most extended "джеки" – Hight Jack and Black Jack.

Find fault Jack joins with брелка – that puts the car on protection, or own. Basically the following is provided: here the car at you have selected, and you "have thrown out". You быстренько press on the button. There is a following further: at once or with a small delay глохнет the engine also joins the alarm system. After that to result the car in a working condition with the help брелков it is already impossible. Certainly, to include Haj Jack it is necessary before the car will leave for action limits брелка. The lack consists that "throw out", as a rule, from the car with keys and брелком, and therefore it is necessary to have all time with itself an additional charm or at least to store the basic separately that, you see, it is not so convenient.

Blek Jack it is not necessary to include. It needs to be switched off. Usually after each opening of a door. Otherwise he warns the forgetful driver, and then stops the engine, but during the moment when the car thief will dump "gas" that does a stop of the car of more safe as for the owner of the car (robbers already far), and for those who goes nearby.
