In cars that do not have ignition switches, the engines are started with a key or a button, but in such cars a chip or key with an electronic mechanism is needed that deprives the vehicle of mobility (English immobilizer - “immobilizer”). This device is found in cars: BMW X3, BMW X5, BMW X6, Mercedes C-Class, etc. If the ignition button fails, you will need to contact the company center to replace it, where you can also find out the prices for this type of work. If you try to do the same operation as with the lock, the engine may not start (on certain models, for example, Audi Q7, Volvo-XC70, BMW-7 series (E-65), etc.).
Sometimes you have to try hard to start the engine in frosty weather. The winter season sometimes becomes a real test for both the car and the driver.
The main reason for difficulty starting the engine is usually an insufficiently charged battery. But sometimes other reasons arise, which can easily be attributed to low-quality oils and fuel. Unfortunately, such factors are discovered too late. And precisely at those moments when you urgently need to go somewhere.

It is necessary to prepare for the morning start of the engine in the winter season in the evening of the previous day. When parking, and especially in an open type, before turning off, press the accelerator pedal and increase the speed to three to four thousand for a few seconds, then sharply turn the key in the lock to position “0”.
In the morning, when you arrive at the parking lot, do not rush to start it right away. Before starting the engine, turn on the headlights for a few minutes. This action will warm up the electrolyte in the battery, which will make it easier to start the engine.
After turning off the headlights, insert and turn the key in the ignition, wait until the fuel pump automatically turns off, and only then try to start the engine by holding the starter key for 20 seconds. If the car does not start on the first try, then you need to take a minute break and then try again to start the engine. To successfully start a car in the morning in frosty weather, as a rule, no more than three attempts are required.

Determine grounding. Usually this is a black or green wire. To check, connect the wire through the tester to the car body. The instrument needle is in the zero position. Therefore, this is “earth”. Once identified, it is advisable to insulate the end of this wire, since accidental connection to the power wires may damage the vehicle's wiring.
Identify the power wire(s). Most often it is a thick wire of yellow or red color. Sometimes there are several power wires. In this case, you need to find them all. Determining the power wires comes down to determining the voltage relative to ground. Using a tester, connect each wire one by one to ground or to the vehicle body. The arrow of the device will show the battery voltage value. Tie the found wires together. Avoid accidental contact with ground or vehicle body.
Identify the wires that supply power to the starter. Place the vehicle's handbrake in neutral. Connect the remaining wires to the power wires one by one. When one of the wires is shorted, the starter will start working. The required wire has been found. The remaining wires provide power to the vehicle.
We connect the power wires to the wire that supplies voltage to the car. Make sure that the connection is strong, as when the car is moving, the wires may become disconnected, causing the engine to stall.
We connect the wire that supplies voltage to the starter to the connection. Let's close. The car starts - we disconnect the wire and isolate it.

note
Under no circumstances should the power wires be connected directly to ground or the vehicle body! The car wiring will burn out. Do not allow power wires to come into prolonged contact with the wires supplying power to the starter.
Situations in which it becomes necessary to start a car without a key are not so rare in the life of an ordinary motorist. After all, both the key itself and the ignition switch break. To cope with a breakdown, you need to know the general principles of operation of car components.
In some situations, it is necessary to start the power supply without using a personal computer (PC). First of all, this is necessary to check the functionality of the component and the voltage at the terminals. Next, we will consider in detail the principle of operation and startup of the power supply without the use of a computer.
Important! Before starting the process, it is worth mentioning right away that starting the power supply (PSU) without using a PC or other load (at least a connected light bulb or cooler) can lead to its breakdown and electric shock, so all actions are performed on at your own risk.
Reasons why you may need to start the power supply without using a PC:
The operating principle of the power supply is based on electricity conversion(mains voltage) to the value required for PC operation. Thanks to this, computer components can operate stably and not be affected by various interferences.
The startup process is as follows:
The first power supplies for PCs were produced according to the AT standard. Thanks to this, the launch could be done without using a PC, i.e. directly. Now the units are produced in the new ATX standard, and idle starting is now harmful to them. They are equipped with SATA and Molex connectors for connecting hard drives and video cards. There are also 4-pin and 8-pin power supply for connecting the processor and 20 pin (older devices) or 24 pin (modern PCs are equipped) for the motherboard.
To start the power supply, you need to know which contacts need to be closed, as a rule, for this use PS_ON connector(green) and COM(black). Next, we will take a step-by-step look at the general steps to start without a PC.
First of all, you need to understand which cables carry what voltage in order to protect yourself. Power supply pinout diagram:
| Color | Voltage level in Volts | Connector number | Connector number | Voltage level in Volts | Color |
|---|---|---|---|---|---|
| orange | +3,3 | 1 | 13 | +3,3 | orange |
| orange | +3,3 | 2 | 14 | -12 | blue |
| black | grounding | 3 | 15 | grounding | black |
| red | +5 | 4 | 16 | Power on | green |
| black | grounding | 5 | 17 | grounding | black |
| red | +5 | 6 | 18 | grounding | black |
| black | grounding | 7 | 19 | grounding | black |
| grey | Power good | 8 | 20 | -5 | white |
| violet | +5 VSB | 9 | 21 | +5 | red |
| yellow | +12 | 10 | 22 | +5 | red |
| yellow | +12 | 11 | 23 | +5 | red |
| orange | +3,3 | 12 | 24 | grounding | black |
Instructions:
note that units equipped with 20 pin and 20+4 pin connectors should not be turned on without load. Otherwise, it may fail.
Regarding the old power supply standardAT- everything is a little different there. Shorting the green and black contacts will not turn on the power supply without the motherboard. In this case, you need to make 2 jumpers and use them to start immediately two combinations: blue - black and white - brown.
ATTENTION! When starting an AT standard power supply, you should be careful! The voltage at one of the closed contacts is 220 Volts!
From an unnecessary power supply it is quite possible to make devices that are useful in everyday life. Next, let's look at how you can use a computer block.
A constant voltage source from a computer power supply is quite a convenient thing. To do this you will need to do replacing resistance coils and remove the choke. Thanks to this, you can adjust the voltage from 0 to 20V. If a standard voltage (12V) is required, then you need to install a thyristor regulator.
To convert the power supply into a charger you will need to perform replacing Schottky diodes to ultra-fast. The main advantage of such a charger is that it is light in weight and dimensions. The disadvantages of this device are its sensitivity to overloads and short circuits. To prevent overloads and short circuits, it is necessary to construct a protection system.
First you need to determine what type of power supply is AT or ATX. Pulse (AT) engines operate exclusively under load, while ATX only needs to be closed to simulate the load, as described in the instructions above. In this case, the output voltage will be from 5 to 12 V. The final values will depend solely on the initial power of the unit.
The skill of starting a power supply without a computer and motherboard can be useful not only to system administrators, but also to ordinary users. When problems arise with your PC, it is important to check the functionality of its individual parts. Any person can cope with this task. How to turn on the power supply?
Previously, there were power supplies (abbreviated as PSU) of the AT standard, which were launched directly. With modern ATX devices, such a trick will not work. To do this, you will need a small wire or a regular paper clip to close the contacts on the plug.
On the left is a 24-pin plug, on the right is an older 20-pin plug
Modern computers use the ATX standard. There are two types of connectors for it. The first, older one, has 20 contacts on the plug, the second - 24. To start the power supply, you need to know which contacts to close. Most often this is the green PS_ON pin and the black ground pin.
Note! In some “Chinese” versions of the power supply, the wire colors are mixed up, so it is better to familiarize yourself with the contact diagram (pinout) before starting work.
So, when you have become familiar with the wiring diagram, you can start starting.
Carefully remove the power supply from the system unit
Connect something to the power supply to create a load, for example, a hard drive
Carefully compare the pin layout on your plug and on the diagram
Make a jumper
We have all seen more than once how in dashing action films the main character starts a car without a key by connecting a couple of wires. Of course, it is possible that a similar situation can happen in life, and it is not necessary to steal a car or participate in a chase. The ignition key may simply be lost or broken during a sudden jerk in the socket. Repairs have their time, but for now you need to somehow start the car without a key. So how to do this? We're not action heroes, so we don't need to rush. Step by step turning on the ignition of a car without a key looks something like this for all car models:
In the case of a car VAZ 2106 You need to remove the ignition cover and find the brown, blue and red wires. The thick red wire is positive. The brown and blue wires need to be secured with electrical tape, and the red wires should be struck on both wires. The car should start. A similar procedure can be done for the VAZ 2109.
To start a VAZ 2110 or 2112 car without a key, you will need to pull out the entire headlight switch so that it dangles on the wires and remove the cover: there will be four connectors. Now you need to insert it differently - into three connectors so that there is one free on the right. At the same time, the fuel pump will start working and the ignition will turn on. Now open the hood. It is necessary to force the starter to start, for which it is enough to bridge the copper bolts, which are located in the back cover of the starter solenoid relay, with a wrench or scissors. The car started.
Activate all emobilizers and do not leave the car unattended in this condition!
You can clearly see how to not only start, but also open a “ten” or “two” without a key in the following video:
Now you know how to start a car without a key. Of course, a considerable number of cars of foreign expensive brands are already equipped with factory buttons and special key fobs; you can often find code panels for entering a PIN code. As for domestic cars, such an easy opportunity to start a car without a key should be alarming - do not leave the car unattended and without an alarm.
Read about opening a car without a key. Well, if you are upset about losing your keys, read our instructions for this case.
Attention
Shorting wires is a dangerous procedure that can damage your vehicle. Never try to short-circuit the starting wires in someone else's car and be prepared to document your ownership of the vehicle.
Hint
If your car only has one ignition wire, touch it to the exposed part of the connected power wires to start the car.
Hint
Modern cars are equipped with complex wheel locking systems and electronic keys, which are almost impossible to bypass without special tools and in-depth knowledge.
Fact
In 2008, the steady decline in vehicle theft in the United States crossed the five-year threshold.
