do they do car key?? if yes, how much for program and cut the key?

They do but very expensive. Google car key replacement. There are many in bucks county for sure

I don't know. You can call and ask, but I believe a place called Stu's does it and will do it for about half the price if you have the materials already (I.e. purchase them off Amazon). Hope this helps.

Not sure. You could just call them and ask.
