General description of the RF transmitter  
 
The RF remote control system consists of a RF transmitter and a RF receiver 
mounted within the control unit. The RF transmitter is mechanically integrated 
in the head of the key. This transmitter is used to transmit an information for 
locking or unlocking the vehicle by an unidirectional RF transmission line for 
normal remote operation by pressing a button. 
 
In general the following functions are provided:
 
 
-  Lock the car 
-  Unlock the car 
-  Unlock the trunk of the car 
 
Power supply

power supply of +3V. 
 
 
Buttons 
 
There are three buttons which enable to lock and unlock the doors and to 
unlock the trunk. 
During activation, the button is forced to the ground via a “pull-up” within the 
microcontroller.
