ID Code Entry ProcedureINFOID:0000000001327833
KEY FOB ID SET UP WITH CONSULT-III
NOTE:
If a key fob is lost, the ID code of the lost key fo b must be erased to prevent unauthorized use. A spe-
cific ID code can be erased with CONSULT-III. Ho wever, when the ID code of a lost key fob is not
known, all controller ID codes sh ould be erased. After all ID codes are erased, the ID codes of all
remaining and/or new key fobs must be re-registered.
1. Touch “WORK SUPPORT”.
2. The items are shown on the figure can be set up. “REMO CONT ID REGIST”Use this mode to register a key fob ID code.
NOTE:
Register the ID code when key fob or BCM is replaced, or when additional key fob is required.
“REMO CONT ID ERASUR” Use this mode to erase a key fob ID code.
“REMO CONT ID CONFIR” Use this mode to confirm if a key fob ID code is registered or not.

KEY FOB ID SET UP WITHOUT CONSULT-III
NOTE:
If a key fob is lost, the ID code of the lost key fob must be erased to prevent unauthorized use. A specific ID
code can be erased with CONSULT-III. However, when the ID code of a lost key fob is not known, all control-
ler ID codes should be erased. After all ID codes are erased, the ID codes of all remaining and/or new key
fobs must be re-registered.
To erase all ID codes in memory, register one ID code (key fob) five times. After all ID codes are erased, the
ID codes of all remaining and/or new key fobs must be re-registered.
