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. For passive access functionality the transmitter is able to reply to an inductive command with sending a remote telegramme. In general the following functions are provided by pressing the buttons: - Lock the car - Unlock the car - Unlock trunc Additional the following functions are provided (Keyless Entry/Go Functions): - Lock/Unlock the car - Start/Stop the engine Power supply The transmitter is provided with 1 Lithium battery (CR2032) that gives a tension of feeding of +3V. The battery inversion is protected mechanically. Buttons There are three buttons which enable to lock, unlock the doors and unlock the trunk. During activation, the button is forced to the ground via a “pull-up” within the microcontroller. LED The LED is turned on between transmission blocks.
