I have a little issue I hope someone can help me out with.

The RX8 I bought only came with 1 regular key and i really want a remote controlled one. The dealer say they need an ID number for the key, wich isn't the chassis or ID number. It's supposed to sit in the front right side door(4-5 digits). I had the door panel off the other day, but only found a number which proved to be the wrong one.
So do anyone know where this number sits and how I can find it?Hoping to save the 100USD the dealer is asking for finding it...

Also a side note, I broke 7 out of 9 plastic clips while taking the door panel off, even if I tried to be careful. Is there a secret trick to getting those things out unharmed, i.e me being a retard, or is the plastic that fragile?

PS: I've searched alot around without finding much on this topic.
