The original keys work perfectly.

CAUSE

Initialization error

MEASURE

Using CIP 15.2 or higher perform the following procedure:

After CIP is started select "Load Software"
Answer "No" to "Have control modules been replaced?"
If a "Status Report" is displayed then continue updating the vehicle software before performing the next step.
Select "Retrofits"
Select "Key CA"
Select "Four Keys" and finish the procedure as instructed by CIP.
This procedure will give the Comfort Access system the ability to use 4 remote control keys (normally the factory has 2 remotes initialized).
