The Immobilizer Key REPLACING THE KEY INTRODUCTION Upon purchase, each vehicle should have two master keys and an aluminum tag with a key-code imprinted on it. To generate a fully functional replacement key (one that will both open the doors and start the engine), one of the master keys is required. To make a key that will open the door for retrieval of items locked inside the vehicle, the aluminum key-code tag can be used. If a master key or the aluminum key-code tag is not available, a Toyota dealer or certain registered locksmiths can obtain the key code from a restricted-access database. These businesses can also access a service utility to reprogram the immobilizer if all registered master keys have been lost. If a Toyota dealer is not available, please refer to www.aloa.org to find a bonded/registered locksmith who performs high security key service. KEEPING THE KEY SAFE Replacing an immobilizer key may be costly. It is advisable to keep a spare master key and the aluminum key-code tag in a safe place. If you record the key-code in more than one place, do not record it in a way that can be easily identified and associated with the vehicle. It is wise to keep a copy of the key-code outside of the vehicle. If the vehicle was delivered with less than two keys and the aluminum key-code tag, consider having the Toyota dealer or a qualified independent automotive locksmith make a duplicate key before you need it. 8 Introduction
