New Transponder Key Code

NOTE: This must be done when a new transponder key ECU is installed. The new transponder key ECU is in automatic key code registration mode. Up to 3 key codes and one sub-key can be registered at one time. In automatic registration mode, last key registered becomes sub-key.
  1. Security indicator will flash until first key is inserted into ignition switch. Insert NEW key in ignition switch.
  2. Once key registration is under way, security indicator should turn off. After key registration is complete, security indicator should illuminate. Remove NEW key.
  3. If programming additional keys, repeat process starting with step  1. If additional keys do not need programming, procedure is complete. Security indicator should go out once last key (sub-key) is registered.
  4. After registration is complete and system is operating normally, when ignition key is removed from ignition lock cylinder, security indicator should flash indicating system is properly functioning. If a key is not inserted into ignition switch with transponder key ECU in automatic registration mode, security indicator will remain illuminated indicating keys have not been registered. If ignition key registration cannot be completed with transponder key ECU in automatic registration mode, a code 2-1 will be displayed by security indicator, and when inserting the already registered ignition key, a code 2-2 will be displayed by security indicator.
