Key Battery Replacement

If the buttons on the smart key are inoperable and the operation indi-
cator light does not flash, the battery may be dead.
Replace with a new battery before the smart key becomes unusable.
The following conditions indicate that the battery power is low:
• The KEY indicator light (green) flashes in the combination meter for
about 30 seconds after the engine is turned off.
• The system does not operate and the operation indicator light on
the smart key does not flash when the buttons are pressed.
• The system's operational range is reduced.
Replacing the battery at your Toyota dealer is recommended to pre-
vent damage to the key. If replacing the battery by yourself, follow the
instruction below.
