Problem:
I was doing a all keys lost on a 2020 Toyota RAV4 proximity I was able to successfully backup up eeprom with Autel KM100 via obd and generate an analog key to turn the ignition on. Once on, I selected add key but was not able to communicate with the vehicle. I also had a jump box hooked up the entire time. Go with manual selection. Any idea on what I need to do?
Solution:
Update
I picked up 2 aftermarket Prox, one 3 button and a 4 button with the same fcc. I was able to program both of them successfully. The only two things I did differently was, hit the unlock/lock a few times on the door before entering the programming procedure and hook up my jumper cables instead of booster.
Push lock unlock door buttons few times.
People do lots of Toyotas and works always.
