Problem:
I’m using the Autel im608 and the FCA bypass cable in a 2021 jeep wrangler Sahara I can read the pin but when I try to program the key it’s failed.. any advice?
Using the OEM key fob.
Solution & Feedback:
The problem was the vehicle battery.. even when it was in 12.54 volts… it wasn’t enough… I used my vehicle to keep it above 14V. And it did work.
Had the same exact thing happen on a 22 durango. it was at my buddies shop and he had been doing other work to it so he just randomly put it on the charger and it worked.
If not working, try disconnect the battery and reconnect so it happened to me I didn’t want to program and disconnect the battery one or 2 min and it was revealed.
