Operation of each component
PRIUS_OM_OM47F32E_(EE)
To take out the mechanical key,
slide the release lever and take
the key out.
The mechanical key can only be
inserted in one direction, as the
key only has grooves on one side.
If the key cannot be inserted in a
lock cylinder, turn it over and re-
attempt to insert it.
After using the mechanical key, store it in the electronic key. Carry the
mechanical key together with the electronic key. If the electronic key bat-
tery is depleted or the entry func tion does not operate properly, you will
need the mechanical key. ( P. 636)
■If you lose your mechanical keys
New genuine mechanical keys can be made by any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer using another mechani-
cal key and the key number stamped on your key number plate. Keep the
plate in a safe place such as your wallet, not in the vehicle.
■ When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press
any buttons on the electronic key while inside the aircraft cabin. If you are
carrying an electronic key in your bag etc., ensure that the buttons are not
likely to be pressed accidentally. Pressing a button may cause the electronic
key to emit radio waves that could interfere with the operation of the aircraft.
