INFORMATION
D
To maintain communication with the
vehicle, smart keys use built−in bat-
tery power. The battery service life
is about 1 to 3 years on average. If
battery power becomes insufficient,
replace the battery with a new one.
D
The smart key continually receives
electromagnetic waves, and if it re-
ceives strong electromagnetic waves
over a period of time, the battery
can be drastically run down. There-
fore, avoid storing smart keys near
any electrical appliances.
Here is a list of electrical
pliances which may have adverse
effects on the smart key perfor-
mance: 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 smart key.
