    All maybe not a thing on k series from that maker . Real debacle rt now chk Autel forums real mess . You need a wireless way to read transponder and Immo info from start button area of car you open door have a good 12 V have you're receiver ready and hold hoop over start button hitting button device . Device pulls ID4 immo info out of car to my device that info burns to a new ID4 compatible remote or whatever protocol is detected they're are many from diff manufactured. Good luck . Londsor k518 watch full videos on a 10 Prius .

    Google UK londsor k518 all keys lost wireless . It's how these protocols for immo work. All these kids running around with the likes of flippers etc. can easily intercept immo info . Course they've to know what to do with. Old code grabbing etc. yes this how they steal too.

    the idea that the car itself broadcasts the information needed to authenticate to it is the most surprising thing i've heard this week
