Just wanted to add my great experience with the "flip Key". I ordered the flip key off e bay about 1 week ago. It came today. First I programmed the lock-unlock which worked perfectly the first time and took about 5 minutes. Then I went to the dealer because some of you have said the dealer would cut the key for free. The dealer could not get the blade into the key machine so I took the key head off as some of you have described and the dealer cut it for free. Then I programmed the transponder. It also worked the first time. All told took less 30 minutes to get fully operational. A question was asked about does it hang down or interfere with leg space? Again no problem.
So the experience so far has been great.
However one question I have is the transponder and the car have to have the same code or the car won't start. If Welly's fob is not as reliable as the Ford OE fob and the transponder fails you might not be able to start the car. Is anyone carrying an OEM fob just in case?
