when you lost your car key,and if you go to 4S store to get another one,it is very expensive. So you can buy a car key programmer to make car key by youself forever.
I see this post without lastest information about skp900 auto key programmer
So I want to share my source to everyone. I found a blog about skp900 tech and support its address :skp900-auto-key-programmer.blogspot.com/
In this blog you can get all of skp900 information,video and software.
