I'm looking to replace a lost '16 Prius Four key fob, and I'd much prefer something less bulky. On eBay, I see several items such as, "OEM Toyota Rav4/Prius Key Fob Alarm Remote Transmitter HYQ12BDM H-CHIP R6". When I check vehicle compatibility with the eBay tool, it claims compatibility with the 2016 Prius Four. Has anyone had experience obtaining and programming such a key? If so, I'd love to hear about it. I would so much prefer to carry around this little key instead of the giant fob.
