That one is a bit out of my league to be honest.
I only got a standard blade cut as a spare to take into the surf while i leave the oem key hidden safely away.
I know that when i use the key blade to unlock the door you have to re-lock the door first before it will allow you to unlock with the key blade, so that may help.
Might be best to call or email a dealer to ask about the other issues.
I believe the key has to be encoded to match your ecu so it may only work for the doors until it is coded correctly (the expensive bit)
