INFORMATION

To maintain communication with the vehicle,
electronic keys use built−in battery power. The
battery service life is about 1 to 2 years on average.
If battery power becomes insufficient, replace the
battery with a new one.

The electronic key continually receives
electromagnetic waves, and if it receives strong
electromagnetic waves over a period of time, the
battery can be drastically run down. Therefore, avoid
storing electronic keys near any electrical
appliances.
Here is a list of electrical appliances which may have
adverse effects on the electronic key performance:
TVs, personal computers, cellular phone or cordless
phone recharger units, electric light stands and
fluorescent desk lights
Note that you should always keep such electrical
appliances at least 1 m (3 ft.) away from the electronic
key.
