The keys are available on the net, i've ordered a 4btn one with SRT on the back. No idea if it's genuine even if they tell you so. i'll find out once I get it. The emergency blade is ordered separately and needs to cut (by code is best) by a reputable locksmith.
They have to be fitted with what's called a PCF7953 Chip. See the info in the PDF.
I have the tool & software to program these so i'm going to have a go when my stock arrives. I'll let you know.
The biggest issue is getting the immo pin code from your dealer. my programmer says it will pull the pin but I won't know until I try. My Dealer got me my code.
doing the 2011-13's is no problem
