Immobilizers are devices that are installed in most modern cars. The main task of them is considered to be reading the code. Thus, the device protects the system from hacking. However, when installing an alarm, drivers encounter problems when starting the car.
In order to solve this problem, there are crawlers. There are not many companies that produce them on the market. Most models are universal and suitable for many brands of cars. To understand the crawlers in more detail, you need to consider their device.
Simple Crawler Scheme
The standard immobilizer crawler circuit includes a CA series bus. It is connected in the device to the module. Controllers in devices are often used analog type. The crawler circuit also includes an antenna. In some cases, there are two. A wire is used to connect the device. Many versions have connectors for various software extensions. Directly at the module is a TV port. According to the protection system, the crawler models are quite different. Power supplies are most often provided for an integrated type.
How to do it yourself?
Making an immobilizer crawler with your own hands is quite simple. The bus in this case is more appropriate to use the CA series. For the model, a two-channel type module is required. Controllers for crawlers are analog. However, some configurations use operational. Next, to make a do-it-yourself immobilizer walker, you need an antenna to transmit the signal.
To connect the device to the unit, a wire is soldered. In some cases, an indication system is installed. This will require three LEDs. They must connect to the module. Relays for crawlers use the RT series. The TV port, in turn, is selected with the marking A25.
Modification with CA bus
Crawler with CA bus is suitable for most modern cars. Modules for devices of this type use two-channel ones. Directly controllers are more common analog. The minimum allowable temperature for models ranges around -30 degrees. These devices are not afraid of frost. The immobilizer bypasser is connected via cables. As a rule, they are 1.5 meters long. Thus, you can install the device under the hood or in the car.
Some modifications provide the possibility of parallel connection to the circuit. A moisture protection system is provided in almost all walkers. Nowadays you can buy a model with a CA bus in the store for 3500 rubles.
Trackers with the PAT bus
The walker with the PAT bus is made only with controllers of operational type. Indication systems for some models are available. Modules are standardly used in the dual channel type. Modifications with two antennas are on the market. The output in the presented configurations is often used three-pin. Software connectors are rarely installed.
TV ports are used by the A25 series. Manufacturers have models with two relays. It is also important to note that these crawlers are not compatible with all security systems. In this regard, modifications with CA buses look more preferable. A car owner can buy a device of this type at a price of 2500 rubles.
Crawler "Starline BP-02"
The specified Starline keyless immobilizer crawler is installed with a CA bus. In this case, the module is used in a two-channel type device. The display system of the model is missing. Installation of the immobilizer crawler takes place only through the alarm system. There are two antennas in this case. Directly the relay in the liner uses the RT series. The power supply for the model is provided with a built-in type of 3 V. The maximum allowable temperature is 40 degrees. The system of protection at the lineman is provided by the manufacturer. You can buy the specified device in the car shop for 3200 rubles.
Model "Starline BP-03"
The indicated Starline keyless immobilizer crawler differs from the previous model by the presence of two relays. Also, in the presented modification, a connector for connection is installed. Thus, it is possible to update the module. The antenna in the device is a loop type. The model is controlled from the car alarm system.
The maximum permissible temperature of the crawler is at around 40 degrees. In cold weather, this device can be used. A cable is included in the standard kit exactly 1.5 meters long. Due to its compact size, this Starline immobilizer without key Starline can be located unnoticed in the passenger compartment. It costs today in car dealerships no more than 3,500 rubles.
Crawler "Starline BP-05"
The specified Starline keyless immobilizer crawler is suitable for most car brands. At the same time, compatibility with popular alarm systems is provided for him. The bus in this case uses the CA series, and the module is installed dual-channel. The display system of the model is missing. There is only one antenna. The controller is used in an analog type walker. Reading the chip code is automatic. Separately, mention should be made of a quality protection system. You can buy the immobilizer liner "Starline" for 3500 rubles.
Modification of "Starline Pandora"
The specified keyless immobilizer crawler is made by the manufacturer with the PAT bus. In turn, the module is a two-channel type. A controller in the casing of the lineman is provided. There are also two antennas for signal reception. The wire is used quite long, so connecting the device to the alarm system is very convenient. To remotely start the car, the specified crawler can be used. Hacking protection is standard. The relay in this case uses the built-in type.
There is no connector for connecting the model to the case. It should also be noted that the presented crawler is deprived of an indication system. This model can be mounted on ties or screws. In general, the case is compact and not afraid of temperature extremes. The ability to update the model in this case is missing. The output of the presented lineman has a three-pin. The maximum allowable temperature of the device is 45 degrees. The power supply for the equipment is 3 V. There is an uninterrupted startup mode in this case. It is also important to note that this crawler has an impulse noise protection system installed. However, the high cost of the goods should be taken into account. The specified device will cost about 4000 rubles on the market.
Features "Starline DI-3"
This crawler can easily be connected to any alarm system. First of all, it is important to note that the connector for updating the module is provided for it. The tire in this case is used by the PAT series. Directly the controller is installed next to it, a single-channel type. Problems with receiving a signal in a device are very rare. For this, the manufacturer provides a loop antenna. The crawler central unit is installed next to the relay.
The TV port of this model has the A25 series. Hacking protection system installed. It can be used to remotely start a car device. It should be noted separately that the power supply is provided for 3 V. The minimum permissible temperature of the device is at the level of -35 degrees. The overload protection system works automatically. You can buy this lineman in the car shop for 3500 rubles.
Starline DI-4 Options
The specified keyless immobilizer bypasser works on the PAT series bus. The system supports many car brands, and there is no need to update the module. The relay in this case uses the usual. A loop-type antenna is standardly installed next to the bus. Indication system is not provided in the device. The specified lineman is mounted on screws. Some install it in the passenger compartment. However, it should immediately be noted that the device is not afraid of temperature changes. For remote start cars, it fits perfectly. The TV port in the presented configuration applies the A25 series.
The maximum allowable temperature is 40 degrees. Support for parallel connection of the device is provided. Direct control of the model occurs through the car's alarm system. The minimum allowable temperature of the crawler is at the level of -30 degrees. The system of protection against impulse noise in this case is absent. On the screeds, the presented device under the hood cannot be fixed. This model is worth about 4 thousand rubles in car dealerships.
