A Few Interesting Facts About Keyless Entry

Today, every modern automobile that has been equipped with an alarm system will also have keyless entry capability. The ability to make use of remote capability to either allow or even deny entry into the vehicle is very useful. The inventor of such systems was a person named A B Makkar. Since the time that this mechanical engineer came up with a system to allow remote access to a vehicle, many changes have taken place.

The main feature of a keyless entry system is that it enables the owner of the vehicle to remotely perform certain functions that do not require having to make any kind of physical contact. Typically, power door locks can be opened or shut from a few feet and even from within a building.

These keyless entry systems work through radio waves that are broadcast on selected frequencies, which typically is 315 MHz (in Japan and in North America) while in Europe the frequency used is 433.92 Mhz. There are also some systems that use more modern technologies which enable the owner to encrypt the system and in doing so prevent car thieves from intercepting these signal which can then be spoofed in order to gain unlawful entry into the vehicle.

The key fob contains most of the functions in such systems. There are also buttons that will either lock or unlock the vehicle doors and there is also a button for opening the trunk. In other cases, the system may also have features that enable the owner to close open windows and the room while remotely locking their vehicles. An even more interesting feature, red panic buttons, when pressed, will activate the car alarm system and so provides an additional security feature.

In order to gain entry to the vehicle without needing to insert a key into the door lock it only requires pressing the right button on the key fob.
