This is a success case for sharing! We newly tested OBDSTAR X300 PRO3 Key Master is OK to program Ford Transit 3-button remote key. Check below steps you can take!
Power up Key Master→ Choose “Vehicles” → “Immobilizer” → “Ford/ Lincoln” →“Ford/ Lincoln V31.09” → “Ford” → “Transit”
Choose “Program Keys”
Use the new key you need to program to turn ignition on. (Now car immobilizer light should blink)
Key Master will ask you to turn on ignition, press ENT button to confirm.
It says this process will not erase key, press ENT button.
Wait a while, it’s communicating.
Now you can see “Program success”, which means you successfully use OBDSTAR X300 PRO3 to program a new working Ford Transit transponder!
Turn ignition off and remove the key.
Insert the key again and turn ignition on. There is no blinking immobilizer anymore!
