New Key cannot be Registered (07/2015 -): Description

If an electrical key transmitter could not be newly registered, wave interference or a malfunction of the certification ECU (smart key ECU assembly), ID code box (immobilizer code ECU), electrical key transmitter sub-assembly, steering lock ECU (steering lock actuator assembly) or door control & tire pressure monitoring is suspected.

The registration to add another electrical key transmitter sub-assembly (without replacing any parts) is called "additional key ID registration".

If additional registration is not possible, refer to "Additional Key cannot be Registered".
