Toyota Corolla Cross (2022-2024) Service Manual / Vehicle Interior / Theft Deterrent / Keyless Entry / Immobiliser System (w/o Smart Key System) / Registration

REGISTRATION

PROCEDURE

1. REPAIR INSTRUCTION

NOTICE:

PRECAUTION WHEN REPLACING PARTS

Code registration is necessary when any of the following parts is replaced with a new one. After replacing a part, any part that has performed registration cannot be returned.
- Transponder key ECU assembly
- Door control transmitter assembly

PRECAUTION FOR REGISTRATION

The door control transmitter assembly has 2 codes: the key code (immobiliser code) and the wireless code (recognition code). Both of these codes need to be registered. For the wireless code registration procedure, refer to Wireless Door Lock Control System.

A maximum of 5 door control transmitter assembles can be registered (this includes any door control transmitter assembles registered when the vehicle was purchased).
If any of the work times are exceeded, finish the procedure.
If the battery is depleted during the key registration procedure, there may be cases in which the door control transmitter assembly cannot be registered again. Therefore, make sure to perform work with a sufficiently charged battery.
Do not perform operations that create an electrical load such as operating the power windows.
Do not disconnect the battery during registration.

HINT:

A brief outline of the key code registration procedure is shown above. For detailed information, refer to the GTS.
If key code registration fails during new key code registration, code 2-1 will be output through the security indicator light. Trying to re-register an already registered door control transmitter assembly will cause code 2-2 to be output when the door control transmitter assembly is inserted into the ignition switch key cylinder. If the number of registered key codes exceeds the maximum limit, code 2-3 will be output through the security indicator light. Details of code output are shown below.

3. NEW KEY ID REGISTRATION

NOTICE:

Immediately after replacing the transponder key ECU assembly, the GTS item "Transponder M-code" should change to "0". If this item does not change to "0", the transponder key ECU assembly may be registered to another vehicle. A transponder key ECU assembly which is registered to another vehicle cannot be used.
When the transponder key ECU is replaced, register all door control transmitter assembles used by the customer.
Registered door control transmitter assembles other than those registered during the transponder key ECU assembly replacement cannot be re-registered, and therefore they can no longer be used.

HINT:

If key code registration fails during new key code registration, code 2-1 will be output through the security indicator light. Trying to re-register an already registered door control transmitter assembly will cause code 2-2 to be output when the door control transmitter assembly is inserted into the ignition switch key cylinder. If the number of registered key codes exceeds the maximum limit, code 2-3 will be output through the security indicator light. Details of code output are shown in "REPAIR INSTRUCTION".

When only one key is desired to be registered, perform following operation 1 or 2 after completing "Process 5".
Operation 1:
1. Insert the door control transmitter assembly into the ignition switch key cylinder and turn the GTS on.
2. Follow the instructions on the GTS screen to end new key code registration.
3. New key code registration is ended.
Operation 2:
- Using a door control transmitter assembly that has already been registered, turn the ignition switch from ON to off 5 times within 10 seconds.
