One key works all of the
lock cylinders on the
vehicle.
Your vehicle has an Immobilizer Vehicle Theft-Deterrent
System. The key has a transponder in the key head
that matches a decoder in the vehicle’s steering column.
If a replacement key or any additional key is needed,
you must purchase it from your dealer. The key will have
PK3+ stamped on it. Keep the bar code tag that
came with the original keys. Give this tag to your dealer
if you need a new key made.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
In an emergency, contact Cadillac Roadside Service
