The most reliable means of protecting the machine from encroachment is to install an alarm. Many owners resort to this method and, as they say, sleep peacefully. Disabling, enabling, reprogramming the security mechanism is helped by a special alarm key fob that comes with each system. It is designed to transmit the command of the car owner to the central control unit, which, in turn, decodes the signal and performs the task.

What is a unique key fob code?

Developers of car security systems are doing everything to provide the greatest security to their customers. Therefore, each alarm key fob has its own unique unique code. This helps to avoid tampering and ensures that another device cannot disable and reprogram the alarm. This code is generated when certain buttons are pressed on the key fob itself. At the same time, they can be programmed for one car.several to replace or supplement. This is relevant when the "native" remote control is broken or lost.

Interestingly, manufacturers of car security systems and car thieves have always competed with each other: the former to make the code difficult to decrypt, the latter to successfully crack the set passwords. It should be noted that the struggle went on with varying success. Yes, and now it is.

Transmitter design: does it really matter?

It is known that a beautiful thing is much more pleasant to use. That is why some companies involved in the production of car anti-theft protection systems are trying to give the remote control an unusual shape. For example, a boomerang or an hourglass is taken as a prototype. But the Starline A-8 alarm keychain looks quite ordinary: a rectangle with a small antenna.

Many will say that the "stuffing" is more important, and it's hard to disagree. And at the same time, girls will appreciate the attractive design elements. Undoubtedly, many companies strive to make their products unique and adhere to their easily recognizable style. Regardless of the external shape, 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 transmitter models are mostly equipped with an LCD display. This is very convenient, because itthe car itself is depicted, and in some emergency, you can immediately see what exactly happened to the car. The distance from which the alarm key fob can successfully transmit signals to the control center of the alarm system varies depending on the model. In most cases, it reaches a maximum of 50 m. There are also those that “beat” at 100 m.

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