Your key number plate and security ID 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. Up to four keys can be registered for use with one vehicle.

For security, all the keys registered with your vehicle’s immobilizer system will have their ID codes erased and reregistered when a new key is made.

Therefore, all of your vehicle’s keys must be presented when a new key is registered. Any key that is not re-registered when a new key is made cannot be used after the other keys are re-registered. For information on replacement keys and on the registration of keys with your immobilizer system, contact your SUBARU dealer.
