Autel KM100 Adds 2021 Ford Mustang Smart Key by OBD

Today I’m going to show how to program a smart key for 2021 Ford Mustang using with Autel MaxiIM KM100 Key Fob Programmer. The process will be the same for all Mustang 2015 or above that have a smart key. This is a push-to-start ignition, and its learning slot is in the cup holder.



Since I already have a working key, and it’s got the remote start. So that I can skip a step there. Let’s get start.

IMMO >> Ford >> Manual selection >> Ford >> USA >> Mustang >> 2020- >> Smart key >> Yes >> Immo status scan >> Add key >> Start
