I got my hands on a 2007 prius, and two smart keys. The owner (family friend) says they had a third but lost it. Hooked up an autel km100, it says there are 3 "master keys" paired to it. How do I remove the extra key? If I have to remove and re-pair one of the keys, that's fine
In Toyota Techstream and in Autel as welll you can do that, but for Prius you need an Autel AP200 and suspect the km100 is not going to offer that.
