Note:
If a variety of similar transponder types are being used, only one representative LCN-ULT
has to be learned. If for example, an EM H4102 and/or a HITAG 1 or HITAG S has to be
learned, the transponder reader then transfers several ID numbers from this transponder
type to the LCN Bus.
If a car key, transponder card or transponder keyring cannot be learned, you should check if
a transponder is intregated. Most of the Mercedes models have no transponders in the key,
they work with an immobilizer on an infrared base. The LCN-ULT cannot read out these
keys.
Should a new generation of transponder chips be produced, that the LCN-ULT doesn´t
know today, the transponder reader can become a new firmware update, by loading a new
software version.
Erasing single transponder types
Hold the master card in front of the transponder reader for longer than 5 seconds, until the
red LED flashes slowly. Now remove the master card again. The mode „erase single
transponder types“ is activated. Now hold the transponder card that has to be erased in
front of the transponder reader, until the red LED stops flashing and the blue LED on the
LCN-ULT lights permanently. This transponder type has now been erased from the type
storage, the ID numbers of several members in this transponder family will not be
LCN-ULT
