been raining/snowing on the Passive Entry
door handle, the unlock sensitivity can be
affected, resulting in a slower response
time.
If the vehicle is unlocked by Passive Entry
and no door is opened within 60 seconds,
the vehicle will re-lock and if equipped
will arm the security alarm.
The key fob may not be able to be detected
