General description of the RF transmitter
The RF remote control system consists of a RF transmitter and a RF receiver
mounted on a control unit. The RF transmitter is mechanically integrated in
the head of the key. This transmitter is used to transmit information for locking
or unlocking the vehicle by a 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 boot lid of the car
- Approach light
- Panic alarm
Power supply
The transmitter is provided with 1 lithium battery (CR 2032) that gives a power
supply of +3V.
Buttons
There are five buttons with following functions:
Action: Usage:
Central locking
Activation of Alarm system
Pressing the lock button
Deactivation of Panic Alarm
Pressing the lock button for 1,5 sec. Comfort closing
Central unlocking
Deactivation of Alarm system
Pressing the unlock button
Deactivation of Panic Alarm
Pressing the unlock button for 1,5 sec. Comfort opening
Pressing the unlock button twice within 10 sec. Two-step unlocking
De-/activation of Approach Light
Deactivation of Panic Alarm
Pressing the approach light button
Pressing the approach light button for 1,5 sec.
Unlocking of Boot lid Pressing the boot lid button Deactivation of Panic Alarm
Activation of Panic Alarm Pressing the panic button for 3 sec or pressing
it twice within 3 sec. Deactivation of Panic Alarm
During activation, the button is forced to the ground via a “pull-up” within the
microcontroller.

Typical usage pattern (for Europe only)
10 lock/unlock operations in 24 hours with complete transmission duration of
1.0 seconds (100ms/operation)
4 lock/unlock operations in 24 hours with transmission duration of 40 seconds (10
seconds for 1 operation; max. value)
→ total transmission duration of 41 seconds within 24 hours
Transmitter ON 1.7 seconds / hour
Transmitter OFF 3598.3 seconds / hour
Duty Cycle: TON / T (ON+OFF) x 100% = 1.7/ 3600 x 100 % = 0.05 %
