The keyless entry system consists of two parts. First of all, the key fob you use to lock/unlock your car, start it, etc. This is the part we have control over. A key fob, as we know it today, is a result of long work and consistent improvement. It is designed to be durable and to last as long as possible. Also, there’s a transmitter and a receiver inside the car. If these three work correctly, you can enjoy fast and comfortable access to your vehicle. Let’s look a little deeper and see what exactly happens when you press the button to lock and unlock your car. This way you will come to better understand your system.
Even though everything happens within seconds, the process is quite complicated. Let’s imagine we want to unlock the car. The Central Processing Unit (CPU) starts working when pressing a button on a key fob. Then, it sends a signal that contains a coded command to the radio frequency (RF) transmitter. Now, a receiver in your car gets the signal, extracts the data, and sends it back to the CPU. The last step is the CPU decodes it and sends the appropriate command, and wallah, the door is open.
Another type of keyless entry system is known as a remote keyless ignition system. Using such a device, you can start a car from a distance just as you open the door. It’s a highly convenient option for time-saving. You can start the car to warm up the engine and the interior of the car as well without having to leave the house and while continuing to get ready.
