the answer is no. The keys use the same 80 bit system, but when you program a key to one car, it will not work another. A key programmed to the focus will only work the focus. if you were to successfully program it to the edge, it would no longer work on the focus.
ps, the dealer should have charged $20-$30 to install those tires. If they were already mounted and balanced on wheels, then technically, its just a tire rotation.
