Hello all, I am new hear, long time lurker, but first time poster. I have a 2015 Prius II with only 1 smart handle (driver side) that unlocks and locks the car by pressing/holding the handle. I know higher trims have the same handle but on the passenger side. I was wondering if it would be simple to buy a replacement smart handle for the passenger side and instal it on my passenger side. Would it work? How is it programed? Does it require a new power source? I tried searching before posting, if there is a previous post, please kindly refer me to it. Thanks everyone!
