2020 INFINITI QX50 key battery

When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key operating range becomes narrower, and
the Intelligent Key may not function properly.
The operating range is within 31.5 in (80 cm)
from each request switch or one touch unlock
sensor
1.
If the Intelligent Key is too close to the door
glass, handle or rear bumper, the request
switches or the one touch unlock sensor may
not function.
If any of the front doors are recently closed
and locked, you must wait 2 seconds before
you can unlock the door with the one touch
unlock sensor. Pulling the handle within
2 seconds of locking the door will allow you
time to confirm that the door has been locked
without accidentally unlocking the door with
the one touch unlock sensor.
If you pull the door handle with your gloved
hand, the one touch unlock sensor operation
may not function. When the Intelligent Key is within the operat-
ing range, it is possible for anyone, even
someone who does not carry the Intelligent
Key, to push the request switch or the one
touch unlock sensor to lock/unlock the door
within range.
