I recently purchased a used Mustang GT 2015 Premium Performance Package that came only with one keyfob. The car starts with a push-button. While I was exploring the menus I stumbled upon the MyKey option. I thought « Why not create one! » without ever knowing all the nightmare it would induce. I lost all performance options including Track mode, Line-Lock, Launch Control and many other important features that the Premium PP1 offers. And the worst of all is that I could not revert back and clear that MyKey since I only had one key fob. I was desperate. More over I had a drag race coming in few days and could not use the track features. Fortunately the pony won the race anyways but with a much slower time and colder slicks. And last week I found this forum. I ordered this
OBD2 module, installed FORScan, followed the workaround procedure provided in this forum and the MyKey is now cleared from my car's computer. Everything is back to normal with Track mode, Line-Lock, Launch Control, as if nothing ever happened. I'll never thank enough FORScan team and the smart user who gave us this workaround!
Here's what I did:
1.
Install this version of FORSCan on a windows 10 - 64bit laptop.
2. Plug the OBD2 – USB module on the laptop. Windows recognized it after a few seconds. Toggle switch to HS-Scan. Keep laptop powered on and unplug module from usb port.
3. Step into my car, install the OBD2 module into the car port, then plug the module into computer usb.
4. Press car push-button without starting the engine.
5. Establish connection with FORScan and let the software read car data.
6. Once I made sure that a good connexion was established between the car and FORSCan I started the engine and let it run for a few seconds. Stop radio, shut windows, and keep steering straight.
7. In FORScan, click on the fourth button that contains test options and choose Key On Engine Running.
8. Launch the test and follow the on-screen procedure until the end of the test.
9. Open driver window, hold the keyfob outside and stop the car.
10. Press push-button to start the system without starting the engine while holding the keyfob outside.
11. Go in settings, MyKey and clear MyKey.
12. That's it!
