Keys The ignition keys are for the ignition
Ody.
The door keys are for the doors anddl
other locks, except the. engine power
switch (if you have a ZR-1) which uses
a third key.
When a new Corvette'is delivered, the.
dealer removes the plugs
from the keys,
and gives them to the-first owner.
However, the ignition key may not have
a plug.
Each
plug has a code on it that tells
your dealer or a qualified locksmith
how to make extra keys. Keep the plugs
' in a safe piace. If you lose your-.keys,
you'll be able to have new ones made
easily using these.plugs. If your ignition
keys dodt have plugs, go to your
Chevrolet dealer for the correct key
code if you need a new.ignition key.
