Standard Key Registration

Standard key registration is required when a standard key is lost and needs to be replaced, or when the code re-registering key is re-registered after the immobiliser unit or ECU are replaced.

NOTE:
Do not start the engine with a standard key that has not been registered. If the main switch is turned �ON� with a standard key that has not been registered, the immobiliser indicator light flashes to indicate fault code �52�.

1. Check the immobiliser indicator light signals the standby mode.
2. Using the code re-registering key, turn the main switch to �ON�, then �OFF�, and then remove the key within 5 seconds.
3. Insert the first standard key to be re-registered into the main switch, then turn the key to �ON� within 5 seconds to activate the registration mode.

NOTE:
The existing standard key code is erased from the memory when the key registration mode is activated. When the key registration mode is activated, the immobiliser system indicator light flashes rapidly.

4. While the indicator light is flashing, turn the main switch to �OFF�, remove the key, and within 5 seconds, insert the second standard key to be registered into the main switch.

NOTE:
If the immobiliser system indicator light stops flashing 5 seconds after the first standard key is registered, the registration mode is deactivated. If this occurs, the second standard key cannot be registered, and steps 2 to 4 need to be repeated to register both standard keys.

5. Turn the main switch to �ON�.

NOTE:
When the indicator light goes off, the registration is complete.

6. Check the engine can be started with the two registered standard keys.
