These keys work in every lock.
Since the doors can be locked without a
key, you should always carry a spare key
in case you accidentally lock your key
inside the vehicle.KEY NUMBER PLATE
Your key number is shown on the plate.
Keep the plate in a safe place such as
your wallet, not in the vehicle.
If you should lose your keys or if you
need additional keys, duplicates can be
made by a Toyota dealer using the key
number.
We recommend writing down the key num-
ber and storing it in a safe place.LOCKING AND UNLOCKING WITH KEY

it.

turning the key once will unlock the driv-
er’s door and twice in succession will un-
lock the driver ’s door and passenger ’s

hicle during an accident. It also helps
prevent the doors from being opened
