Hi there,
I purchased the following key for my 2015 RAV 4 XLE (http://tiny.cc/d7llfz) for $40, had it cut from my master key for $2 at our local locksmith and bought this OBD Remote Key Programmer (http://tiny.cc/x9llfz) for $36 to program both the transponder and the remote and it worked like a charm. It literally took me under five minutes to accomplish both. I also used the excellent instructions a successful customer provided within Amazon: http://tiny.cc/2nmlfz
I hope this helps!
