Alfa 145 - Transponder type

[Xndirt]

I am looking for one car key programmer to duplicate one spare key. Found one ND900 key tool, it said that can identify, write and copy transponder and also can calculate transponder codes and pin codes. But it is so pricey. I think it is for mechanic or someone who own a car repair business. So any devices like ND900 but much more affordable for car owner？

And how can I know the transponder type of my alfa 145?
