The way a keyless entry system functions is by releasing radio signals and then searching for a corresponding response signal from the key fob.

Some systems have a second transmitter on the trunk of the car which can be opened when you put one foot underneath it.
Each key fob is equipped with a unique digital identification code, which is given by the manufacturer. A unique process of technology known as "programming" is used to set the fob up with a specific car's system. This typically involves turning the car's ignition repeatedly in a specific sequence. It could also involve pushing or pulling different buttons and levers, or removing fuse.
Once the key fob is programmed into your car's keyless system, it transmits a digital identification code as well as a function-code to instruct the car on what to do (lock or unlock the trunk). The receiver on the car checks the authenticity of the transmitter by an authentication and encryption process. The computer in the car will allow the vehicle to be opened and start the engine if it is authenticated.
There are fears that a clever criminal could intercept the code that's transmitted between the key fob and the car. This would require a device to record the transmission and then transmit it again in the event that the system doesn't anticipate it. Most keyless entry systems utilize the rolling code method to stop this. This ensures that each new signal from a transmitter received by a car has a counter that differs from the previous one.
