Remote Key Initialization: Notes

The initialization of the FZV keys is required to establish the Lock/Unlock signal synchronization with the GM V. The initialization procedure provides the GM with a key identification number and a "rolling code" for each key. If the initialization is not performed, the GM will not respond to the key signals.

Up to 4 remote keys can be initialized. They must be initialized at the same time. Key initialization is only possible with the vehicle unlocked.

Procedure: 

1. Close all doors and have all keys available.
2. Using key number 1, turn the ignition switch to KL R, then switch off within 5 seconds and remove the first key.
3. Within 30 seconds of turning the ignition switch to "off" Press and hold  button #2. 
4. While holding button #2, press and release  ("tap"  ) button #1 three times  within 10 seconds.
5. Release both buttons. The LED in the key will flash momentarily. The GM will immediately lock and unlock the doors signaling a successful initialization.
6. If additional keys need to be initialized repeat steps 3 - 5 within 30 seconds.
7. Switching the ignition to KL R completes the initialization.

SERVICE NOTE:  The key memory function of the GM responds to the key identification number of each key. If the keys are not initialized in the same order prior to initialization, the key memory functions activated by the keys will not be assigned correctly.

Always initialize the keys in the same order.
