Anti-theft mechanical devices for cars can be used as a primary or additional security device. They are divided into eight types, depending on which element of the car will be blocked. In this case, it is enough to install just one type of device to prevent theft.

What types of anti-theft mechanical devices are there for cars?

Automotive devices designed to protect the car are divided into several groups:

for gearbox;
to protect the engine compartment;
on the steering shaft;
for ignition switch;
on the car door;
for steering wheel;
on the pedal;
for installation on wheels.

Transmission locks

This type of locking device is divided into several types:

Arc devices. When turned on, these models lock the transmission lever in a certain position. The lock is secured using a special bracket that wraps around the gearbox lever. Modern models of devices are equipped with special larvae characterized by high cryptographic resistance. To ensure the highest possible security, a floating password is used, making hacking almost impossible. The key disadvantage of gearbox locks is the large size of the devices.
Pin blockers. This type of device is considered more advanced compared to the arc lock for gearboxes. The main component of the design is a steel pin, which is used to lock the gearbox. When activated, driving the vehicle will be impossible. The body of the device is made of high-strength steel. Compared to arc locks, pin devices fit harmoniously into the interior of the car.
Pinless type of blockers. This type of device is considered more modernized. The process of blocking a manual transmission or automatic transmission is performed directly inside the device. Activation and deactivation of equipment occurs only using a key.

Hood locks

This type of device is designed to protect elements and assemblies located in the engine compartment. The level of reliability of the device is determined by the security of the larva itself. If this component is vulnerable, it can be easily hacked.

The main disadvantage of hood locking devices is the low security of the drive cable, which is designed to open it. If a criminal gains access to this element, he will hack the device without entering the car interior.

Steering locks

This protection option is designed to prevent the steering wheel from turning. The devices are installed directly under the column, next to the pedal.

Structurally, such a blocker consists of several elements:

locking device;
locking mechanism;
automatic latch;
coupling;
screws;
key or secret button.

The principle of operation of the locking device is to fix the steering shaft using a coupling, which consists of several elements.
This part rotates along with the steering wheel when the lock is not working, so it is impossible to notice it. To turn on the device, the car owner needs to install the locking mechanism in the groove and close the device. This will lead to the fact that on one side the steering wheel, when turning, will rest against the engine shield, and on the other, against the pedal. The steering shaft lock is difficult to pick. The most effective type of locking devices are devices with secret buttons that do not use keys. You can bypass such a mechanism only by cutting it with a grinder.

The channel “Andrey Kondrashov - copyright protection against theft” presented a test of popular locks for steering shafts and talked about the advisability of their use.

Ignition switches

If a hacking attempt occurs, the contacts in the device will open, which should close when the power unit starts. When installing the lock, its switch should be brought out and masked. Otherwise, the criminal will be able to start the internal combustion engine. Ignition switches can be touch controlled or radio controlled.

Locking devices of this type are made of high-strength alloy steel. The design of the lock is based on a high-secrecy mechanism. Depending on the model, the blocker can be additionally equipped with protection for the starter unit from being turned on again.

To install the ignition switch, it is recommended to contact specialists; there is a risk of making a mistake when performing the task.

Door locks

This type of device is used to prevent an intruder from entering the car. Devices of this type are presented in the form of a metal pin that blocks the door if it is not locked. Activation of the device is carried out using a key or key fob, it all depends on the type of device.

Steering wheel locks

This type of system is used for mounting on the steering wheel rim or in its spoke. The principle of protection is based on the fact that the criminal will not be able to turn the steering wheel in the event of a break-in. The second part of the lock product will always rest against the door or dashboard of the car. There are devices for the steering wheel, one part of which is placed directly on it, and the second - on the pedal.

You can bypass such a device without any difficulties. But if the device is equipped with a secret, then this will be problematic.

The “Baza Avtozvuka” channel talked about protective devices designed for installation on wheels.

Pedal locks

There are two types of anti-theft devices of this type:

Thrust mechanisms that prevent pressing the gas or clutch pedal. The main disadvantage of such a device is the inconvenience of installation. But this minus for the consumer can become a plus, since it is almost impossible to hack the larva if it is stolen. Due to the inconvenient location, even a weak secret will not be able to be opened.
Supporting devices. A device of this type blocks the possibility of moving the pedal with one part, and the second clings to the steering wheel of the car. Installation is simpler than thrust mechanisms, but this type of device is characterized by large dimensions.

Wheel locks

They are designed to block the drive wheel, making it impossible to move the machine. The product is mounted on top and secured to the disk. The main disadvantage is the inconvenience of operation. The device is large in size, so it must be carried in the trunk.

The use of wheel locks is important if the car remains in an unguarded parking lot for a long time.

TOP 10 self-protection against theft

03/18/2020, author: Alexander Vizaulin

It seems that none of you will have to prove that a car is not only a convenient means of transportation, but also an object of increased attention from criminals. The latter highly and truly value your car, dreaming of rushing off with it to the “beautiful far away” finally and forever. What can I say - there is only one way to prevent such an unpleasant outcome: equipping your vehicle with a security system. Moreover, not a simple standard one, which an experienced hijacker can hack in a matter of minutes, but a truly reliable one, with multi-level authorization and carefully disguised control units.

Unfortunately, after purchasing a new or used car, the installation of a decent anti-theft system is sometimes postponed for one reason or another: some people still don’t have enough time, others don’t have enough money, and others even believe in the modest capabilities of the above-mentioned factory security tools. The disadvantages of this approach are obvious, and therefore we decided to tell you how you can at least slightly increase the level of protection of your car yourself, without spending your last salary on it. So, what can we do to further puzzle the hijacker?

Simulation of alarm

This is the cheapest, and therefore most primitive, instrument, the operating principle of which is based on a purely psychological effect. Essentially, this is a small plastic block with an LED that simulates the operation of a security system. It costs a penny, can be purchased in many domestic or Chinese online stores, but can only mislead a novice thief. Some of them immediately reveal their fake essence upon closer inspection through the windshield, others are a little more complicated, but the essence is the same - apart from the appearance of having an “anti-theft”, they are of little use.

Rating of mechanical blocking companies

To choose a high-quality protective device, it is recommended to familiarize yourself with the brands and models that consumers prefer:

Interception Universal;
Python;
Knight Barrier;
Guarantee;
Defen Time;
Barracuda.

Interception Universal

The device is made in the form of a metal cylinder, which is mounted on the steering column. The device is fixed in a certain position, and when it is closed, turning the steering wheel will be impossible. The body of the blocker, as well as its protective part, are made of stainless steel, which contributes to longer operation of the device due to low wear.

Due to the absence of a keyhole, higher reliability is ensured. The device is turned off using a key made in the form of a ring with notches. On average, the price of the product is about 6500-7500 rubles.

Advantages:

compatibility with more than 50 car models;
The device does not require maintenance.

Python

The operating principle of the device is based on blocking the steering wheel from turning. To perform the task, a special long pin in a leather case is used. The key feature is the implementation of effective protection against various hacking options. The device performs simultaneous blocking of both mechanical and electronic components. This refers to both the steering wheel and the starter mechanism.

The device is protected by additional protection against the use of master keys and similar products for picking the lock. If a criminal manages to open the device, then the internal combustion engine will not be able to start. To activate the starter mechanism, a special button installed on the key fob is used. The cost of the set is approximately 7,600 rubles on average.

User Perehvatsz spoke about the features of the Python locking system for cars.

Knight Barrier

The device is made of high quality stainless steel. The manufacturer provides a five-year warranty on the product. The steering wheel lock is equipped with a keyhole located on the side. It is characterized by an unconventional shape, which makes it difficult for the device to be hacked. To open the device, not standard keys are used, but rather unusually shaped controls.

Main advantages:

the product does not require periodic or routine maintenance;
the original shape of the device will not allow the thief to use master keys or bumping;
Suitable for most modern car models.

Guarantee

This manufacturer supplies the market with two effective protection options - Bastion and Block blockers. Both Garant models are characterized by high secrecy of the internal cylinder. The device effectively protects the starter mechanism from restarting.

Main advantages:

the warranty service life is five years;
The device is suitable for installation on most modern cars;
the device is made from high-quality carbon steel, which prevents rapid wear;
The locking device is based on the Abloy lock, characterized by high secrecy.

To operate effectively, the device requires periodic maintenance and lubrication. The average cost of a set is about 7500-800 rubles.

Defen Time

The hood lock of this brand will effectively protect the engine compartment. The key feature of the device is the use of modern protection technologies during production. In practice, it is almost impossible to hack the product. This is due to the high-strength materials from which the device is made, so it is difficult even to cut it with a grinder. Depending on the model, the cost of the device can range from 2,500 to 7,000 rubles.

User Alexey Lyamin spoke in detail about the features of using Defen Time hood locks.

Barracuda

This brand produces both locks and locking devices for certain vehicle models. In this case we mean anti-theft devices for transmissions. On average, installing a locking device can take up to two hours. On sale you can find universal products that are mounted in standard places, as a result of which you do not have to drill additional holes.

Locking devices are characterized by rigid contours. This increases the mechanical strength of the device. On average, one lock will cost the buyer 4,500 rubles.

How does a secret car work?

The owner of a security device with a manual or automatic transmission must press a special button before starting the internal combustion engine. If the anti-theft system on your car is equipped with a magnet, then you need to attach the key to it and enter the password. Depending on the type of anti-theft device installed, you may need to turn the key additionally. If a thief manages to hack the security system and the siren does not produce alarm signals, he will need time to find and disable the button.

The detailed operating principle of the secret system is discussed using the example of a simple but effective blocker:

The car owner enters the code after stopping the engine. This allows you to lock the steering shaft.
If a criminal tries to steal a car and start the engine, the engine will start. However, it will randomly stop after a few minutes. This option is implemented by the developers so that the hijacker cannot travel far.
If the criminal finds the location where the security device is installed, he will try to enter the code. As a result of several unsuccessful entry attempts, all major vehicle systems will be locked.
Perhaps after this there will be attempts to steal a car by unlocking the nodes. In this case, the mechanisms will begin to emit alarm signals, scaring off the criminal.

The Axius-Auto channel talks about the principle of operation of the device using the example of the Igla model and a Range Rover car.

How to make a mechanical anti-theft device with your own hands?

The easiest option is to block the vehicle's exhaust pipe.

To make an anti-theft mechanical device for a car you need:

Drill a hole in the pipe.
A special cylindrical part made of steel is installed into it.
Another hole should be made in the center of the cylinder.

The bottom line is that by installing this element in the hole in the exhaust pipe and turning it, the exhaust gases will be blocked. They will not be able to get out, as a result of which the car engine will not start. If you turn the cylindrical device with a hole towards the exhaust gases, they can leave the car. In fact, this anti-theft device is a regular faucet.

There is another option - to make a lock that is primitive in design to prevent the clutch pedal from moving. As a base, you will need a steel bracket, the body of which has holes of the appropriate size. A lock will be inserted into them, which will lock.

1) A syringe with 5-10 cubes of formic acid from the back of the seat at lumbar level and driven by the gas/clutch/brake pedal - in Soviet times there were such crafts from car thiefs, as a rule the car thief with a severe subcutaneous burn lies near the car (there is crime) 2 ) gas pepper spray driven by an actuator. The diagram is on your fingers: we place the can in a pipe of a suitable diameter (we make an eyelet at the pipe to install the rod, glue/attach the can. We attach the actuator to the pipe, attach the rod to the button and into the eye. You can hide it anywhere under the panel, 5-7 seconds after triggering — you understand where your eyes go. You control it from a button: press it, it’s armed. You do the triggering, for example, on the gas pedal mic, the clutch. Well, set the shutter speed for 10 seconds, otherwise you’ll eat yourself)))

This is tough, like a boxing glove to the face)

And there is such a thing - the airbag module is placed in the corner of the passenger's headrest - side impact and face into the steering wheel

Normal anti-theft ;-) I have the same one on my bike :-D

In my opinion, insurance is the best option.

It’s much better to prevent the hassle later than to suffer later, and no matter how there is no iron friend, the loss will not be without a trace, even if they are returned under insurance

The main thing is to move the diagnostic connector to another place so that the keys are not quickly removed.

My rear gearbox could not stand it and fell apart. The bridge is jammed. Everything works, but the car doesn’t drive) And the simplest anti-theft method is to blur the inhibitor wire (selector lever position) And until you close the wire back, even though you have a different brain, even a different braid and a bunch of bottles of gasoline, even the starter won’t turn)

Do you mean the wire from the gas pedal or from the throttle position sensor?

Wire from the gear selector switch position: park, drive, neutral, reverse, etc.

I have a mechanic

Then release the gas pedal

I’d like to know which wire to open there) I’ll look it up and google it)

I just wanted to write about the secret, you beat me to it. in addition, you can put a reed switch on some wire of the diagnostic wire...

You can install any systems, they are all from pioneers,” because the pro comes with a bottle of fuel, which is pumped up to 5-6 bar and will last for 5-10 km. — you don’t need a fuel pump, they come with their own wiring and ECU, then you don’t need anything at all. Mechanical systems can be easily opened, for example with a bumper - ru.wikipedia.org/wiki/%D0...C%D0%BF%D0%B8%D0%BD%D0%B3 ,

The only thing is that any system complicates any action and scares many.

where will he put the bottle of fuel? ) MB in VAZES this is what rolls in an expensive foreign car, at a minimum you need to open the hood

Where I go with my braid. Read the Internet. In more than half of the cars, the tank is under the rear seat and there are quick releases on the pump.

in focus, by the way, to get to the pump you first need to cut a hatch in the metal))

Where I go with my braid. Read the Internet. In more than half of the cars, the tank is under the rear seat and there are quick releases on the pump.

What if the fuel supply is cut off in the system? And the fuel doesn't reach the engine?

Half of the cars have a connector on the fuel rail to check the pressure, connect it there and it’s fine, and in the system you either shut off the return line or there is a valve.

You need a lot of time this time

Why do you need these homemade products, it’s easier to install a guarantor or one similar to it, but it’s better to have a guarantor, because you’ll go crazy cutting it, it’ll take about 20-30 minutes for sure

The old method is to disconnect the chip from the ignition module.

Maybe it would be better to break the wire from this chip and remove the microphone?

Shut off the fuel or the crankshaft sensor. There is an electric valve on the fuel line, and the driver pulls the wires from it into the headrest. seats. The button is on the bottom right under the casing. And there are no wires visible, and there is no button)))

then turn off the power to the ecu which is permanent plus find horseradish

The simplest thing is to break the circuit of the DPKV sensor with a micro-button only to you in a known place, without it the car will not drive away under its own power, the solution itself is cheap

The wire resistance will change, will the DCCV work properly?

will not affect, find the pinout of the harnesses and use a minimally short wire

Hidden button under the carpet from the fuel pump. So I’ll tell you one story. Previously, there was Smirnov vodka in plastic flasks...in general, it doesn’t matter, take any bottle of vodka or whiskey in plastic, if possible, and add cyanide in it...carefully mask the hole and put it in the glove compartment. The person who used this in the 90s found his car within a few hours on the Moscow Ring Road with two corpses in the car. The cops couldn’t prove anything... it’s up to you what you carry in the glove compartment.

Well, there is one more interesting tip for searching. You buy an old iPhone, charge it in a circuit and hide it, for example, in the seat, turning on silent mode. Online via “Find iPhone” you will always see on the map where the car is... you can detect this beacon only by diagnosing a power leak

I heard a similar story, only there was a man who drove to his mistress on a penny in Soviet times, and there someone got into the habit of getting into his car to warm up. The man got tired of this, he took a bottle of vodka, pumped out a little and injected either methanol or some other freshwater into it, in the end one glued his fins together in the car, and the other in the neighboring yard, they also dragged him for interrogation, so he told them : Show me the report on the discovery of my prints on the bottle, that’s where it all ended

They tried to sell him on premeditated murder
