Would these work on 2014 Ford Mustang ?

Ford explorer 2007 i have just one original key will this function for me...? i also have a ford explorer 2002 same situation....

You should be able to get the keys cut at some place like a Home Depot or hardware store. They will then work in the doors. I think you'll have to have a dealer or locksmith program at least on of the keys. there are plenty of YouTube videos about the procedure for programming the vehicle to recognize the keys. Contrary to how it sounds, you're not actually programming the keys. Each key has an RFID (Radio Frequency Identifier) chip in it that transmits it's unique identification number when it is placed in an appropriate energy field (it's generally in the steering column and/or the ignition lock housing). If the number matches one which the body controller recognizes, it will allow the vehicle to start & run the engine so it can be driven, otherwise it won't and the vehicle is not drivable. What you are doing is telling the body controller to remember the transponder code from a given key's RFID chip as a legitimate key so the vehicle can be driven. The remote door lock controllers work similarly - the instructions for programming the remotes can be found in the owner's manual for your specific vehicle. Sorry I could not be more helpful.

I have an original key and one I had programed by the dealer will they work for duplicating a new chip key

As long as you have 2 working keys you can program the new keys.
