			=== Program tramsmitter key ===

			<!-- GF80.30-P-3002SM, Program transmitter key, function MODEL 220, 215 as of 1.10.02 with CODE (889) Keyless go, 30.9.04 -->

			====General information====
			As of [[facelift]] vehicles, the keyless go function has been integrated
			into the transmitter key (A8/1) eliminating the keyless go transmitter card (A8/2).

			Data between the transmitter key (A8/1) and the EIS control unit (N73)
			are transferred via the keyless go control unit (N69/5).
			The access authorization and the drive authorization is accomplished
			between the transmitter key (A8/1) and the EIS control unit (N73)
			via the overhead control panel control unit (N70).

			====Procedure when replacing keyless go control unit====
			Connect STAR DIAGNOSIS system to data link connector (X11/4).
			Select menu "Keyless go" in STAR DIAGNOSIS with "Start-up" function.
			Then follow individual items in menu.
			To complete start-up, erase DTC memory in keyless go control unit (N69/5).

			====Procedure for use of spare key====

			Case 1: Program spare key on present key track.
			Insert spare key to be programmed into EIS control unit (N73).
			A rotate enable is given after approx. 30 min.
			Then switch on c.15.
			After a further 90 min., the vehicle is again operational and the
			selector lever can be moved out of position "P".
			Assignment has been successfully completed.

			Case 2: Program spare key on new key track (additional key).
			Insert additional key to be programmed into EIS control unit (N73).
			For the spare key, the authentication value, IR signal and radio
			signal are synchronized at the start whereby the programming
			time is for at least 1 minute.

			In both cases it is necessary to synchronize the transmitter key (A8/1)
			in the keyless go control unit (N69/5) with an existing or new key rail with STAR DIAGNOSIS.

			Frequencies for central locking are:
			* In Europe 433.92 MHz
			* In USA (and Australia) 315.00 MHz

			\|}

			====Reception ranges====
			The inductive antennas generate fields to cover various reception ranges around the vehicle.
			The transmitter key can determine its position in relation to the vehicle from the overlap of several fields.
			The range is approx. 1.5 m.

			====Function prerequisites====
			The keyless go control module (N69/5) causes the transmitter key (A8/1)
			to send its authorization code via radio and inductive antennas if:
			* a hand is inserted into a door handle (capacitve sensor);
			* a door handle is pulled;
			* the lock button on one of the door handles is pressed, the trunk lid release switch (S15/1) is pressed to open the trunk lid;
			* the trunk lid keyless go button (S62/21) is pressed;
			* the keyless go start/stop button (S2/3) is pressed.

			The capacitive sensors are only active for 72 hours after the
			last locking operation and when play protection is not active.

			====Function sequence====
			The vehicle wakes up the transmitter key.
			The transmitter key determines its position in relation to the vehicle
			and transmits this information to the rear window antenna amplifier module (A2/12) with the authorization code.
			The rear window antenna amplifier module (A2/12) converts the radio signal into a data signal.
			The overhead control panel control module (N70) receives this data signal via a data line.
			The code included in the signal for authorization is transmitted to the EIS control module as CAN message.
			The EIS control module (N73) checks the code and, if the code was correct,
			sends the corresponding command for lock/unlock or for engine start via the CAN data bus.
