The main functions of the Starline immobilizer crawler, features

Keyless devices are more difficult to implement, but better protect against theft. Specially designed electronic units control the bypass of the Starline immobilizer via a radio channel or via a local CAN bus.

The StarLine immobilizer crawler will help to provide remote autostart of the engine without disabling the security function. The compact module can be placed in a suitable location near the instrument panel.

Characteristics of the crawler on the regular immobilizer "Starline"

Widespread car theft protection systems, in addition to alarms, include additional devices. Among them are controllers for fuel supply units, starter and ignition control. Their condition is regulated by the immobilizer. This is an electronic access unit, it allows starting the engine and moving from a place if it detects a chip integrated into the ignition key and the owner's radio tag in the identification zone.

If you need to remotely start the power unit and heat the interior, the presence of the owner is not necessary. On command from the key fob, the StarLine a91 immobilizer crawler imitates the presence of a key in the lock, and the engine starts. At the same time, the movement of the car is prohibited until the radio tag of the owner is detected.

Immobilizer bypass

The StarLine immobilizer bypass module can be standardly integrated into the anti-theft system, or implemented as an additional unit. Its task is to remove the ban on starting the power unit. At the same time, the blocking of the systems responsible for the start of movement (automatic transmission, travel sensor, tilt, etc.) is preserved.

What is the crawler for and how does it work

In the parking lot, it may be necessary to warm up the passenger compartment and units in the engine compartment in the absence of the owner. Remote engine start is provided by the Starline immobilizer crawler using:

• imitation of a native ignition key inserted into the lock;
• software control via CAN and LIN buses.

The first method is divided into 2 options:

• use of a physical duplicate key;
• integration into the anti-theft system of an electronic device-transmitter in the form of a miniature board.

In terms of protection against hijackers, the crawler of the first type is inferior to the second. Accordingly, its cost is less, and installation is simpler and does not require professional skills.

All you need is a copy of the ignition key with a chip and strict adherence to the instructions supplied by the StarLine manufacturer.

It works like this:

1. On command from the owner's key fob, the central immobilizer control unit supplies power to the relay.
2. Its contacts complete the communication circuit.
3. A scanner antenna located on the ignition lock cylinder picks up pulses from a duplicate key that is hidden nearby, usually behind the dashboard.

Thus, starting and running of the engine are allowed. But the car will not move until the owner's motion release radio tag appears in the detection field.

What is the difference between a keyless crawler and a regular one

Keyless devices are more difficult to implement, but better protect against theft. Specially designed electronic units control the bypass of the Starline immobilizer via a radio channel or via a local CAN bus.

How the StarLine immobilizer crawler works without a key

There are two options for implementing such a scheme with the installation of additional electronic modules. Their connection with the blocking control device is carried out through special connectors. To activate the keyless immobilizer crawler use:

• wireless communication via radio channel (to simulate the ignition key without its physical engagement in a hidden place near the lock, for example, StarLine F1);
• control via standard CAN and LIN buses (StarLine CAN + LIN).

The second method is more reliable and is implemented in the StarLine A93 2CAN+2LIN (eco) product, however, it may not be compatible with some car models.

Modifications of crawlers StarLine

The youngest and simplest model is the VR-2. Next come the more advanced StarLine BP 03, BP-6, F1 and CAN + LIN immobilizer crawlers. Key simulators are similar in principle of operation and are easy to install. Software tools are more complex, but have greater reliability and flexibility in customization. When buying such a device, make sure that the car is equipped with local wired data buses.

Rating of the most popular models with customer reviews

In the most branched line of StarLine a93 car alarms, any type of immobilizer crawler can be used - both software and inexpensive key. There are several options to choose from, differing in functionality and compatibility with the Smart Key.

Bypass module StarLine BP-02 ("Starline" BP-02)

An additional chipped ignition key is placed inside a 20-turn coil that acts as an antenna. Both of its ends are brought to the contact block of the StarLine immobilizer bypass block, and one of them has a break switched by the relay. From the block, two wires lead to a second coil inductively connected to an anti-theft questionnaire placed around the ignition switch.

Until a command is received from the remote control, nothing happens. After the start signal, the relay is energized. The direct communication circuit between the antennas around the key and the immobilizer transponder is closed. In this case, the control system receives the code for unlocking the motor.

Comments in the reviews indicate the difficulty of choosing the optimal location for the block for smooth operation.

Bypass module StarLine ВР-03

This is a modification of the BP-02 model. There is a wire loop on the outside of the case. Two problems may arise during installation:

• insufficient inductive coupling for reliable operation.
• lack of space for installing an additional loop antenna for the StarLine BP-03 immobilizer crawler.

In the first case, the loop is left intact, and the ends of the coil that fits the chipped key are inserted into the gap of the standard scanner antenna. In the second case, the antenna is made independently, and the loop is cut. In this case, a regular frame with a diameter of 6 cm is not used.

Starline Bp 03

The reviews note that the StarLine BP-03 immobilizer bypass module has the option of manually winding the antenna (several turns around the ignition switch). This can improve the communication and reliability of the device.

Bypass module StarLine BP-06

The block has been improved to work with a Smart Key. Added additional connectors with purple and purple-yellow wires for data exchange with the central unit via a digital channel.

According to reviews, this is the best option, since it excludes the influence of pickups and does not require intervention in the regular circuit. Can be mounted in any convenient place.
