Your key number plate will be required if you ever need a replacement key made.
Any new key must be registered for use with your vehicle's immobilizer system before it can be used. The maximum number of keys that can be registered for use with one vehicle is as follows.
One key that has already been registered is required in order to register a new key.
If you lose a key, the lost key's ID code still remains in the memory of the vehicle's immobilizer system. For security reasons, the lost key's ID code should be erased from the memory. To erase the lost key's ID code, all keys that will be used are required.
For details about new key registration and erasing the lost key's ID code, contact your SUBARU dealer.
