Skybrake immobilizer: principle of operation, features, installation and dismantling

When the anti-theft device is activated, the power plant is blocked by a relay. It is better to replace the failed element of the control unit immediately: look for a used relay at the disassembly. Or have the old one repaired by an experienced electrician.

Modern cars are regularly equipped with electronic means of protection against encroachments of ill-wishers - "immobilizer" systems. An interesting development in this segment is the Skybrake immobilizer. The smart anti-theft device is built using the Double Dialogue (DD) wireless technology.

The principle of operation of the Skybreak immobilizer

Miniature electronic "guards" can block the fuel system, or, like the Skybrake immobilizer, the car's ignition. At the same time, the immobilizer of the Sky Brake family eliminates interference and prevents signal scanning. The owner of the machine, at his choice, sets the range of the device - a maximum of 5 meters.

Engine protection is provided by an electronic key with a label. When the user leaves the antenna coverage area, the engine is blocked. An attacker can detect and disable the burglar alarm. But an unpleasant "surprise" awaits him - the engine will stall in less than a minute, already on the way.

The principle of operation of the immobilizer "Skybreak"

Diode bulbs and sound signals give the car owner information about the status of the device. How to "read" indicator alerts:

• Flashing in 0,1 sec. – the blocking of the motor and the controller is not active.
• Beep 0,3 sec. – Skybreak is off, but the sensor is in operation.
• Quiet sound - the power plant lock is on, but the sensor is deactivated.
• Double blinking - immo and motion sensor are working.

The wireless transceiver of the security mechanism determines whether the key is in the sector of the control unit. Only in this case is it possible to start the motor. If the antenna did not detect the tag, to start the engine, you need to enter a four-digit pin code sewn into the system at the factory.

How does the Skybreak immobilizer behave if you get into the car without a special key:

• 18 sec. the wait lasts - the signals are “silent”, the motor is not blocked.
• 60 sec. the notification function works - with extended signals (sound and blinking of the diode), the system warns that there is no key. Motor lock is not yet active.
• 55 seconds (or less - at the choice of the owner) the final warning is triggered. However, the power unit can still be started.
• After two minutes and a few seconds, the "Panic" mode is activated with the motor blocked. Now, until the key appears within the range of the antenna, the car will not start.

At the moment of "Panic", an alarm is triggered, the alarm lamp flashes 5 times per cycle.

What are the main functions of Skybrake immobilizer

Anti-theft devices are available in two versions: DD2 and DD5. Hidden "immobilizers" turn off the vital functions of the car. At the same time, it is difficult to detect and neutralize protective equipment.

Skybrake immobilizer functions

Both electronic devices have similar characteristics:

• channel frequency for "Double dialogue" between the key and the control unit - 2,4 GHz;
• antenna power - 1 mW;
• number of channels - 125 pcs.;
• protection of installations - 3-ampere fuses;
• the temperature range of both models is from -40 °С to +85 °С (optimally - no more than +55 °С).

DD5 transmits packet data faster.

For version DD2

An ultra-small mechanism is installed in the motor wiring harness. The device blocks the circuit using relays built into the base unit. The energy consumption of each lock is 15 A, the battery lasts up to a year for the Skybrake immobilizer.

In the DD2 blocker, the "Anti-robbery" function is implemented. It works like this: the Skybrake immobilizer looks for a tag on the radio. Not found, begins a 110-second countdown, then locks out the propulsion system. But the sound detector is activated beforehand.

The Skybrake immobilizer battery lasts up to a year

Features of the device:

• anti-robbery and service modes;
• identification of the owner by radio tag;
• automatic blocking of the engine when the key is at a distance from the control unit.

The less interference around the machine, the better the protective device works.

For version DD5

Compared to its predecessor, the DD5 has undergone major changes. Now you have a personal transmitter in your pocket or purse, with which you do not need to do any manipulations - just have it with you.

Device DD5

The compact dimensions of the control unit allow you to install the device in hidden places in the cabin, under the hood, or another convenient corner. The design of the model includes a motion sensor.

Thanks to the author's encoding, such a device is not amenable to electronic hacking. The tag works continuously, as it beeps when the key's battery is critically charged.

Immobilizer package

Microprocessor-based stealth devices are easy to use and do not give car thieves a chance to succeed.

Standard equipment of the immobilizer "Skybreak":

• User's Manual;
• head system microprocessor unit;
• two radio tags to control the blocker;
• two rechargeable batteries for the key;
• password to disable the system;
• LED lamp;
• buzzer.

Immobilizer package

Simple in design, the device can be installed independently. The price of the product without installation is from 8500 rubles.

Detailed installation instructions

Turn off the car. Further actions:

1. Find a hidden dry corner in the car.
2. Clean and degrease the surface where you will mount the base device.
3. Place the immobilizer box, secure with double-sided adhesive tape or plastic ties.
4. Install a buzzer inside the machine so that the upholstery and rugs do not muffle the sound of the machine.
5. Mount the LED bulb on the dashboard.
6. Connect the "minus" of the head unit to the "mass" - a convenient body element.
7. "Plus" connect through a 3-amp fuse to the ignition system switch.
8. The instructions for the Skybrake immobilizer recommend connecting pin No. 7 to an LED and an audible signal.

Contact No. 1 blocks the wiring, which should have a standard voltage of 12 V.

Frequent malfunctions and their solutions

The Skybrake engine blocker is a reliable and durable security equipment. If it works intermittently or does not respond to the RFID tag, check the car battery.

After self-diagnosis of the battery, troubleshoot:

• Examine the energy storage device. Make sure that the case is not cracked, the electrolyte does not leak, otherwise change the device. Pay attention to the terminals: if you notice oxidation, clean the elements with an iron brush.
• Unscrew the battery banks, check the electrolyte balance. Add distillate if necessary.
• Measure the voltage in the battery. Attach the multimeter probes to the battery clamps ("plus" to "minus").

The current in the device must be at least 12,6 V. If the indicator is lower, charge the battery.

Label failure

Security equipment may not work due to a malfunction of the radio tag. If the manufacturer's warranty for the product has not yet expired, you cannot interfere with the design. When the term has expired, you can open the radio tag, inspect the board. Wipe traces of oxides found with a cotton swab.

Radio tag malfunctions

If the pins come off, solder new pins. A common cause of key failure is a dead battery. After replacing the power supply, check the operation of the anti-theft device.

Non-working processor unit

If everything is in order with the label, the cause of the malfunction may lie in the microprocessor control unit.

Node diagnostics:

• Find the installation location of the module, inspect the plastic case: for mechanical damage, cracks, chips.
• Make sure that moisture (condensation, rain water) has not entered the device. A damp device will not find the tag on the radio, so disassemble and dry the mechanism. Do not use a hair dryer, do not put equipment near heat sources: this can only do harm. Collect the dried device, test the performance.
• If melted or oxidized contacts are found, replace and resolder them, following the Skybreak immobilizer connection diagram.

After all operations, the block should work.

Engine not blocking

When the anti-theft device is activated, the power plant is blocked by a relay. It is better to replace the failed element of the control unit immediately: look for a used relay at the disassembly. Or have the old one repaired by an experienced electrician.

Problems with sensor sensitivity

You can diagnose the motion controller yourself.

Problems with sensor sensitivity

Follow the advice:

1. Take the driver's seat, remove the battery from the key.
2. Start the engine.
3. Immediately go outside and forcefully slam the door or swing the body.
4. If the machine does not stall, then the sensitivity of the part is at the proper level. When the operation of the power plant stopped, the blockage worked - reduce the sensitivity indicator.
5. Now the parameter needs to be checked in motion. To do this, repeat the first and second points.
6. Start driving slowly. There is no battery in the key, so if the sensitivity is set correctly, the car will stall. If this does not happen, adjust the controller.

Do not forget that anti-theft equipment does not work with a blown fuse, a dead battery, a broken standard electrical wiring, and many other reasons.

Disabling the immobilizer

The owner receives a unique four-digit password along with the device. Deactivating the device using a pin code is simple, but the manipulation takes some time:

1. Start the engine, wait for the lock to turn on (a buzzer will be heard).
2. Turn off the engine, prepare to enter the password (its four digits).
3. Turn the ignition key. When you hear the first warning signals, start counting them. If the first digit of the code was, for example, 5, then, after counting 5 sound pulses, turn off the motor. At this moment, the control unit "remembered" the first digit of the password.
4. Start the power unit again. Count the number of buzzers corresponding to the second digit of the pin code. Turn off the motor. Now the second digit is imprinted in the memory of the control module.

Disabling the immobilizer

So, having reached the last character of the unique code, you will turn off the immo.

Deleting a tag from memory

Sometimes there are situations when the key is lost. Then you need to erase the information about the label from the device’s memory.

Procedure:

1. Remove the batteries from the remaining keys, start the engine.
2. When the buzzer beeps that the engine is blocked, turn off the ignition.
3. Start the engine again. Start counting pulses to ten. Switch off the ignition. Repeat this two times.
4. Turn the motor on and off after the first or second pulse, depending on the radio tag number (on the product case).
5. Now enter the pin code of the new key: turn on the ignition, count the buzzers. Turn off the motor when the number of signals matches the first digit of the new code. Repeat the action until you enter all the numbers one by one.
6. Switch off the ignition. The security device will transmit short signals, the number of which will be equal to the number of radio tags.

Having lost the key, you should buy only new tags, but not a piece of equipment.

Dismantling

Remove all security equipment in the reverse order of installation. That is, you first need to disconnect the wires: "minus" - from the body bolt or other element, "plus" - from the ignition switch. Next, remove the box with double-sided tape, buzzer and diode lamp. Dismantling completed.
