Title: THEFT DETERRENT / KEYLESS ENTRY: SMART KEY SYSTEM (for Start Function): New Key cannot be Registered; 2018 - 2022 MY Camry [03/2017 - 08/2022] |
New Key cannot be Registered
|
DESCRIPTION
If a new electrical key transmitter sub-assembly could not be registered, wave interference or a malfunction of the certification ECU (smart key ECU assembly), electrical key transmitter sub-assembly, steering lock ECU (steering lock actuator or upper bracket assembly) or door control receiver assembly is suspected.
The registration procedure 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.

HINT:
If any of the following have been performed, registration of all electrical key transmitter sub-assemblies is necessary:
-
The certification ECU (smart key ECU assembly) has been replaced.
-
The certification ECU (smart key ECU assembly) and steering lock ECU (steering lock actuator or upper bracket assembly) have been replaced.
