go off accidentally, or the door lock pre-
vention function may not operate.)

may not operate, depending on the loca-

tion of the key (close to a spare tire, the 

inside edge of the luggage compart-

ment), conditions (inside a metal bag, 

close to metallic objects) and the radio 

waves in the surrounding area. (
