You can purchase a new key at yourToyota dealer if you can give them thekey number and master key.
Even if you lose only one key, contactyour Toyota dealer to make a new key. Ifyou lose all your master keys, you cannotmake new keys; the whole hybrid vehicleimmobilizer system must be replaced.
See the suggestion given in “Keys” onpage 20.
If your keys are locked in the vehicle andyou cannot get a duplicate, many Toyotadealers can still open the door for you,using their special tools. If you mustbreak a window to get in, we suggestbreaking the smallest side window becauseit is the least expensive to replace.Be extremely cautious to avoid cuts fromthe glass.
