Not sure about the app, but i'm sure it would work
That app does work to unlock the car. And, while the app's "unlock" command might save you in an emergency, I personally wouldn't purposely
rely on the app to get you back in your car.
Remember that the app does not communicate directly with the car. The app commands first travel over the internet (via your phone's internet connection), are processed by the MyFord Mobile servers, and are then sent to the car (via the car's wireless data connection). If any of the links in that chain are not working when you need to get back in your car, then you could be suck out of it for a while.
For example, what if your phone doesn't currently have a signal and/or internet service? Or, what if your phone's battery simply died? What if your car is out of cell range (on whatever wireless network Ford uses in your area)? What if the MFM servers are down for maintenance?
