Secret for your car

Hello, friends the inhabitants of our site! In this article I want to tell you how do it yourself You can make a secret for your car. You say why the "secret"? But because only you will know about the place of its installation. How does she work? A reed switch is installed in a convenient, inconspicuous place under the plastic inside the car. You sit in the cabin, insert the key into the ignition switch, bring a small magnet to the installation location of the reed switch, start the engine. Then the magnet can be removed, car will work. If you do not attach a magnet to the reed switch, you will not start the car. Homemade scheme shown in the photo.

It works as follows. When the contacts of the reed switch are closed, power is supplied to the relay K 1. It works, and its contacts K1.1 self-locks. In this state, the relay will remain until the ignition is turned off. The second contacts of K1.2 will include a previously open power supply circuit of the starter relay or the fuel pump relay, and so on. You can open any power circuit, any automotive relay. In addition to the starter solenoid relay circuit, since the reed contacts do not withstand high currents. Yes, and the contacts of the K1 relay then must be designed for more current. When the ignition is turned off, the power circuit of the above relays will be open again.

To assemble this homemade product, we need the following parts and tools:

This is any small-sized relay that reliably operates from 12 V, with two pairs of open contacts. It is possible and automobile. Reed switch, small magnet, mounting wires.

Instruments: Soldering iron, solder, tweezers, wire cutters, pliers, electrical tape or cambric.

We assemble as follows:
Step 1. We solder the parts according to the scheme. Check the correct assembly.

Step 2. We connect 12V power from the power supply or from the car battery.

The plus of the power supply is per reed switch, and the minus one pin of the relay coil winding 1. To the K1.2 contacts we connect a multimeter in the resistance measurement mode.

Step 3. We bring a magnet to the reed switch.

(I have it in a plastic case, like the reed switch itself)

I used the reed switch brand IO102-! 6 / 2. And then everything is described above. After the reed switch is triggered, the multimeter shows that the K1.2 contacts are closed, thereby closing the circuit of the fuel pump relay cut off by us. We remove the magnet - the circuit still remains closed.

All this is shown in the photo.

Step 4. Install homemade in the car. And check her work.

I end it all.
I wish you all success in your work!
See you again.

R555,
This is a burglar alarm. And in my homemade products, for example, Magnet Tester, I make it clear that miracles can be done with a hidden magnet, reed switch and magnet ...

Himself the same, my gate opens like that. Electric strike and reed switch. Well, the radio remote controls from the UMB trinkets. Well, for those who are especially stubborn, who dare to climb - there are a couple more unexpected people. xaxa
A small zilch of fucarcin with green will make the thief colorful. cray This is exactly the color of fucarcin, just like a handkerchief in snotty erysipelas.

Leobrynn,
But what to do so that flowers from the lawn are not rubbed - there are no thoughts except for boards with self-tapping screws.

In the late 80s and early 90s for landing inadequate made a device simulating a malfunction or a complete engine stop. After trying to take the car away, he made a device for immobilizing the car after removing the living or ..... owner from it. Then there was the device "friend or foe" - the car "asked" who controls me. Then there was a car self-liquidation device after a certain number of unauthorized launches, etc. Such were the times.

You can simplify the circuit using an additional relay with one pair of contacts. Simply connect the k1 and k2 diode (cathode of the diode to k1). K1.1 contacts turn out to be superfluous.

Do not stop wondering where you all live? !!!!

I never cease to be surprised! Where are you!!! Do you live? In the Novosibirsk Akademgorodok, on November 16, 19.19 (not at night) Nissan Almera was hijacked from a huge GSK to 1700 garages. Kemerovo citizens. We arrived at the Loaf, opened the garage, stole benzo and power tools. Yes, and the car. The gayts caught them already on the highway 60 km from the city. By chance. You need to read the morning reports of the Ministry of Internal Affairs.

And I once on the "Sotka" barked the clutch master cylinder. Late evening. And in the morning you need to go far and be sure. Since there were already prerequisites for this, the cylinder was already purchased. I, as one said, everlasting, "I knew that it would be bad, but I did not know that so soon!" ...
He took a flashlight, and, right at night, near the entrance, he began to change! And the cylinder is under the clutch pedal! It is necessary, pushing into a full seat, and bending the letter "si", to lie on his back through the threshold, poking around under the pedals.(Fortunately, "Sotka" is not a small car. There are quite a few places))).
So, for an hour of work, they tried to stretch me twice by the legs because of vigilant neighbors who saw through the window that someone was busy at night with a flashlight in the car.)))))

In the 90s there was a joke. I then lived in a "small-family communal apartment." In the morning I go out to warm the car (winter). Started, lit, stand. I look, near the car of my friend some guy is messing around. Tries to open with a steel ruler through the gap between the glass and the molding. I wanted to approach, but here the owner himself leaves the entrance. But I must say that he then worked in the police. A simple sergeant-driver UAZ. And there was a huge growth and a huge physique !!! And, like most "enormous by nature" - the calmest quiet kind person!))) (They haven’t need to prove anything to anyone from this point of youth!))) That’s how this character is formed)))).
He came to me, said hello. (In the "citizen"). I told him - they say take a look that this is happening with your "audyuha"?)))). He calmly approaches that and sympathetically asks, "Che, has you locked the key inside?" He replied: "Yes, no! There is a key! (Shows). Something with a lock!". Sasha, politely, suggests: "Maybe mine will do?" And gets his own, which is suitable !!! (At the same time, I am shifting to the side on the most likely escape route)))) ... But man ... DOES NOT RUN !!!
Surprisedly, he blinks his eyes ... Looks into the salon ... And "turns white !!!" .. He began to stutter already !!!
... HE MIXED THE MACHINE !!!
Came out ... It’s still dark ... Powdered by snow ... I tried to open it ... It doesn’t work ... I went for the line ...)))))
P.S. Would Sasha have such a character? ))))) ... Yes, at least, as I have (then)))) ... I remember, when I retired to the position, I began to knead my shoulder.))))

Relay K 2 will turn on after the operation of contacts K 1.2. And they, in turn, will be closed after closing the contacts of the reed switch, to which the magnet will be brought.

I put a car in the city this year, removed the BB wires, threw off the terminal. Then he came to leave, he just opened the hood and the police arrived right there xaxa

The scooter ran out of gas in a very fast town, got up, I was driving around with the hoses hoping to get something done, literally a minute and the police were near me. From such things.

But for opening the doors through the window (lock wedges) no one ever said anything.

Try messing with 1.5l. a flask of gasoline from AUCHAN, etc. with a tambourine dance, wires and jumpers.

In my car, about 10 years ago, the lock in the driver's door deteriorated. Could not open. I fiddled with her for about 50 minutes, even tried to break the glass in the door. It was a day in the middle of Samara. During this time no one approached me and asked what I was doing and why. Only an hour later, a man left the house and asked what I was doing there. It turns out that all this time he was watching me from the window of his apartment on the second floor.
And you say Auchan xaxa There you are not interested in anyone at all.

Even in the 90s, cars were opened at night. The radio was filmed. And now, who has heard about this? especially since the cars now have "native" immobilizers ... And you can’t remove the radio tape recorder.))

I installed such garbage (with some modifications in the form of LEDs, etc.) already on 15 familiar cars 15 years ago, on three. A trip to the store, a shopping center full of peace is provided for. Try messing with 1.5l. a flask of gasoline from AUCHAN, etc. with a tambourine dance, wires and jumpers. For my car I’m calm for at least 1.5 -2 hours. And so decide for yourself.

I will upset you a little.
On any injector car:
1) Disconnect the air duct from the air filter. We leave attached to the damper body.
2) We take a bottle of PET for 1.5-2.5 liters with gasoline and a hose for 3-4 mm. We feed gasoline in a thin stream into the duct. A second hose from the cap connects the bottle to the atmosphere.
3) We connect an ordinary multivibrator on one relay to the low-voltage terminals of the ignition coil (without radio components in general)
4) Turn on the starter, start the car and drive it around the corner.
It's all.
If someone is embarrassed by paragraph 3, then we study the material part - instructions for the emergency start of the ZIL-131 car.
All this I have done more than once, when I need to deliver a "dead" car at least to the asphalt, and already on the "tie".

Yes, we don’t have such pronounced ones ... More precisely, there is, of course ... How could it be without them.))). And even two syringes I somehow saw near the railway tracks in the nook. So there are nariks! But somehow, especially "out of sight." Work on them constantly.
And at night such a contingent of homes sitting directly shown. You don’t particularly like the night streets, without attracting the attention of the police - they will rake and determine until the morning. So, at night with us, basically, only decent people walk around the city!))))
Young people are raging that, they say, "There is no freedom," "There are too many cops." And as for me - a quiet life is also worth something.))) There, in the same Odessa I was, so there are apartment thefts so far, and even the cars were gutted. And the streets at night is not entirely safe to walk with money.)))
Not. I do not want. Better a lot of cops!))). The crown will not fall, even if it is stopped by mistake. They are, after all, polite. They are punished under the Law on Polite Treatment of Citizens even for raising their voices and screaming even in RESPONSE.

And, it happens, often, the instrument travels in it (grinders, etc.). And I don’t take it ... Who is climbing cars now ?! Not those times! It’s not worth it ... They will find, most likely, with the current abundance of cameras and with the current normal operation of the cops.))).


You forget about drug addicts, drunks, and other inadequacies who don't care if they find them or not. They take and steal, sell, then look for fistulas, try to find out from them where they shared the thing, and if it dies at all? He will find a passport, smoke another, or leave a cigarette butt in the car.
But you don’t need to close it from the pros ...

It needs to be complete paranoid to remake the wiring of the computer or take it home.

Sogdashen by 1000%.))) Once I bought an "Opel Omega", in which the German owner was paranoid))). There was a secret there too. True, it was made very professionally - the ignition key socket in this car is located in a circular recess, a kind of shallow “well”. High-class car - the panel there is "soft". In this "well" from the side closer to the driver, a micro button was mounted under a soft coating. Those. after you turn the key (or along with this movement) it was necessary to swipe your finger in this place. Otherwise, turn the starter until blue in the face - will not start. It’s done correctly - even if an intruder “with a reconnaissance purpose” travels with you as a passenger and carefully observes twenty car windings, he will not notice this movement, even if you are not going to hide it !! (After all, all you need is to slightly extend one finger when turning the key all the way into the wall of the "well", which is not noticeable at all.) I even joked my friends into a frenzy, proving to them that my Omega only recognizes me. ))) They suspected a "secret", carefully watched ... But ... They didn’t succeed!)))). But if the driver before the factory will bring something somewhere, I’ll be the first to wonder what kind of dances he plays with a tambourine?)))). Purely out of curiosity.)))
P.S. But that Omega was released in '97 !!! Then it was somehow justified ...(Although it’s all the same, it’s paranoia !!! Although it’s old, but it already had an immobilizer, a chipovanny key and an additional installed Pantera.))))))
P.S. And now I have been working as a minivan in work, for example, for the last two years, the lock on the rear passenger and on the trunk hasn’t been working ... Too lazy to poke around .... Spends the night at the entrance ... And, often, the tool drives it ( grinders, and so on). And I don’t take it ... Who is climbing cars now ?! Not those times! It’s not worth it ... They’ll find it, most likely, with the current abundance of cameras and with the current normal work of the cops.))) ... There, even the paid guarded parking lots were already closed ...

Yes. But there is an ECU. To it goes a wiring harness with a standard wiring. You can change it to a non-standard, known only to the owner. And change it on the connector, and change it on the computer itself as well (it is clear that you have to cut and re-solder a bunch of tracks on the board). After that, that’s all. He took the computer home - he won’t budge.

The idea is 40 years old.
An attacker, if he suddenly gained access to a car, always knows where the fuel pump relay is located, the main relay and other relays involved in starting a particular car. Even if he does not know, he will throw a couple of jumpers and all things.
By the way, on modern cars there are no high-voltage wires.

interesting, but this should be put under a well-protected hood. Although, under a normal hood, you can also throw off the terminal with akb, and for paranoids - pick up a high-voltage wire.

In any case, if an attacker gets under the hood, he will start the car, well, if not completely dumb)
