KEYS
The key operates all locks on your vehicle. You should always carry a
second key with you in a safe place in case you require it in an
emergency.
If your vehicle is equipped with the SecuriLock™ Passive Anti-theft
system, your keys are coded to your vehicle; using a non-coded key will
not permit your vehicle to start. If you lose your dealer supplied keys,
replacement keys are available through your authorized dealer.

ignition.
The vehicle can still be locked, with the key in the ignition, using the
manual lock button on the door, locking the driver’s door with a key, by
simultaneously pressing button 7

keyless entry keypad (if equipped), or using the lock button on the
remote entry transmitter (if equipped).
