Alarm Key Ring - car security alarm control system

The most reliable means of protecting the machine fromencroachment is the installation of an alarm system. Many owners resort to this method and, as they say, sleep peacefully. Disable, enable, reprogram the security mechanism is helped by a special alarm stick that comes with each system. It is designed to transfer the car owner's command to the central control unit, which, in turn, decrypts the signal and performs the assigned task.

What is a unique keyfob code?

Developers of car security systems makeall to provide the greatest security to their customers. Therefore, each alarm keychain has its own unique code. This helps to avoid outside interference and ensures that the other device can not be turned off and the "signal" programmed. This code is generated when certain buttons are pressed on the keyfob itself. Thus for one car they can be programmed several for replacement or in addition. This turns out to be relevant when the "native" remote control is broken or lost.

It is interesting that manufacturers of security systems forcars and hijackers always competed among themselves: the first for making the code heavy for decryption, the latter to successfully crack the installed passwords. It should be noted that the struggle was with varying success. Yes, and now it is.

Design of the transmitter: is it so important?

It is known that a beautiful thing is much more pleasantto enjoy. That's why some companies that are engaged in the production of auto theft protection systems are trying to give the remote control an unusual shape. For example, a prototype is taken with a boomerang or an hourglass. But the Starline A-8 alarm stick looks quite ordinary: a rectangle with a small antenna.

Many will say that the "filling" is more important, and with thisit's hard not to agree. And at the same time, girls will appreciate attractive design elements. Undoubtedly, many companies strive to make their products unique and adhere to their easily recognizable style. Regardless of external outlines, each alarm keychain has a very small size, easily fits in the palm of your hand and weighs only a few tens of grams. This makes it as easy to use as possible.

Some features of the device and operation of key fobs

The latest models of transmitters, for the most partequipped with LCD display. This is very convenient, because it depicts the car itself, and in some emergency situation, you can immediately see what happened to the car. The distance from which the alarm keychain can successfully transmit signals to the control center of the alarm system differs depending on the model. In most cases, it reaches a maximum of 50 m. Also produced are those that "beat" and at 100 m.

In most cases, the keychain worksalarms from ordinary batteries, which are popularly called "little fingers". They need to be changed about once a year. Some models of the remote control have a special indicator that shows the level of charge. This is quite convenient and excludes the situation of a sudden failure of the transmitter due to the inadequacy of the battery.
