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 switched 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.
