Technical Description and User’s Manual of the DAG Key Gen. 6
1 General operation of the key
The DAG Key Gen. 6 consists of a HF transceiver. It is used to transmit the information for locking or
unlocking the vehicle by an uni-directional (Remote Keyless Entry RKE) or bi-directional (Keyless
Go/Start operation after a LF Wake Up KG) HF transmission.
At KG the Vehicle Key reacts on a LF Wake Up-Signal from the vehicle (initiated after push of the
Start/Stop-button of the vehicle or a sensor, which recognizes the wish to lock or unlock the vehicle or to
open the trunk) from the vehicle and after that a bi-directional HF communication for autorization is initiated. When the authorization is successful the vehicle performs the desired action.
For RKE there are two separate buttons each one for locking and unlocking the vehicle. The keys for all
vehicles with a boot lid are additionally equipped with a third button to open or close the trunk. The key is
provided with an additional button to (de-)activate the “PANIC” function for the vehicles intended for the
US market.
2 Buttons
3 Buttons
2 Buttons + Panic
3 Buttons + Panic
In general the following functions are provided:
- Lock the car (KG and RKE)
- Unlock the car (KG and RKE)
- Open/Close the trunk of the car (KG and RKE, only 3 button variants)
- (De-)Activate Panic Function (only RKE and USA variant)
- Engine Start of the vehicle (KG)
For emergency start, when the battery power is too low, the DAG Key Gen. 6 has a bi-directional very
short range (< 10cm) LF-Transponder interface .
2 Operating frequencies of HF transferral
2.1 3-channel
Up to 3 channels are possible. The following table shows the carrier frequency of the individual channels
for each frequency band.
Frequencies
Frequency Variant Channel 1 (CH1) Channel 2 (CH2) Channel 3 (CH3)
433.92MHz
433.47MHz
434.37MHz
433.92MHz
315MHz
314.00MHz
314.90MHz
314.45MHz

2.2 Operation of channel-frequencies and power-modes
Normally each key operates in 3-channel mode at the respective frequencies listed above. Since some
countries allow operation with higher HF-transmitter power, the key fob can be configured between two
RF power modes.
When individual frequencies of the 3 HF-channels are not allowed to use this channel(s) will be switched
off. This especially information depends on the countries and is available by the country code of the electronic ignition switch. The key changes its operation at the first time it is be authentically used. The
change of used channel frequencies and power mode is durable locked and can not be changed after
this.

5 Declaration of Conformity, product Label
5.1 Radio equipment authorization to FCC in USA
FCC ID: YGOHS1
The transmitter will be supplied as an original equipment device to the car manufacturer.
According to 47 CFR 15.19 (labeling requirements) the car manufacturer will print the following text in the
appropriate User’s Manual of the car:
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
Usually this is followed by the following FCC caution:
Any changes or modification not expressly approved by the party responsible for compliance
could void the user’s authority to operate this equipment.
5.2 Radio equipment authorization to RSS-210 in Canada
IC: 4008C-HS1
The transmitter will be supplied as an original equipment device to the car manufacturer.
According to RSS-210 (labeling requirements) the car manufacturer will print the following text in the
appropriate User’s Manual of the car:
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject
to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio
exempts de licence. L'exploitation est autorisée aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, mêmesi le brouillage
