ZKE - Remote control (RC) of the central locking system (ZV)
This functional description contains information on the subject of logging RC keys on/off at the ZKE. To replace the ZKE, observe the instructions provided.
In the central body electrical system, four remote control keys can be coded for the central locking system. These keys contain three different codes. These codes are set in the control unit at the factory by the bar code tag. With every vehicle delivered, these bar code tags are attached to each RC key.
Important: Inform the customer that these bar code tags are to be kept in a safe place. The data is only stored on the bar code tag and in the ZKE control unit.
Example: a number-letter combination as shown below is printed on the bar code tag.
*02535EE2535EDFFA**FFFFFFFFDACA115*
Delete the following positions from the sequence: 1,2,17,18,19,34,35. This results in this sequence:
__2535EE2535EDFF___FFFFFFFFDACA11__
Sort this sequence!
2535EE - base code (positions 3 - 8)
2535ED - random code (positions 9 - 14)
FFFFFFFFFFDACA11 - encryption code (positions 15, 16, 20 - 33)
Logging an additional RC key on at the ZKE
Procedure:
In the service program at <Service functions> - <Body> - <ZKE central electrical equipment unit> - <ZKE / RC key>, select the item ”Reading key data”. Read the ZV codes of all keys. Select a key position that in all codes is only ”F”. This key position is free. In the service program, select the item ”Log on key”. Write the ZV codes into the ZKE corresponding to what appears on the bar code tag. It is only permitted to write the data on a free key position! Follow the instructions in the service program.
