Keys
A
CAUTION:
Leaving young children in a vehicle with the
ignition key is dangerous for many reasons.
A child or others could be badly injured or
even killed.
They could operate power windows or other
controls or even make the vehicle move. Don't
leave the keys in
a
vehicle with young children.
Your Park Avenue has a two key system, one key is the
master and the other is a valet key.
