Remote Key Initialization

The initialization of the FZV keys is required to establish the Lock/Unlock signal synchronization with the GM. The initialization procedures 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 key signals.
Up to 4 remote keys can be initialed. They must be initialized at the same time. Key initializations is only possible with the vehicle unlocked.

Procedure:

1: Close all doors and have keys available
2: Using key number 1, turn the ignition switch to KLR, 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 the arrow button *Unlock Button*
4: While holding the arrow button, press and release (“tap”) the roundel three times within 10 seconds. *Lock Button*
5: Release both buttons. The GM will immediately lock and unlock the door 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 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 function activated by the keys will not be assigned correctly.
