Had them do the install...They got it working, but I was less than impressed with them. had to take it back twice.... first time was because they needed the 2nd key which they didn't tell me about and then second time was because I was driving down the road leaving their shop and my door locks were going nuts, horn honking and all sorts of crazy stuff. They also didn't put the screw trim covers back on and had to search the shop for them when I noticed and came back.
