DIY PROGRAMMING INSTRUCTIONS FOR GM VEHICLES WITH PUSH-BUTTON IGNITION THAT USE SMART KEYS FEATURED BELOW:

A. Programming with Two Working Smart Keys

Before you start programming, make sure that the vehicle engine is off and all smart keys, both currently working and new, are with you. Please read and understand the programming procedure before you begin. You can also find instructions specific to your vehicle in the vehicle owner’s manual. Up to 8 smart keys can be programmed to a vehicle.

1. Remove the emergency key blade from one of the working smart keys.
2. Place the two working smart keys in the cupholder.
3. Insert the emergency key blade into the driver door lock cylinder, then turn the key counterclockwise to the unlock position five times within 10 seconds. (on some vehicles, you will need to remove the lock cylinder cap on the driver door handle to access the door lock)
The Driver Information Center (DIC) will display READY FOR REMOTE # 2, 3, 4, etc
4. Place the new smart key into the transmitter pocket (inside the center console storage area between the driver and front passenger seats for Cadillac vehicles OR in the front cupholder for Chevrolet and Buick vehicles).
5. Press the ENGINE START/STOP button. When the new smart key is recognized by the vehicle the DIC display will show that it is ready to program the next smart key.
6. Remove the smart key from the transmitter pocket and press the LOCK or UNLOCK button on the remote.
