IM guesing since its aftermarket key dealer wont help.You deffinetly need it programmed.Just recently only dealers did programming but a locksmith in my ares does it payed 40 for spare.The key wont program itself.

 

According to both Ford dealers, it is a Ford OEM key.

Here is the new key at top, and the original keys at the bottom.

The car itself should program the key. According to the instructions, it requires two already working keys to do it.

Right, just like my 2004. The 2015 process is unknown to me, but here is a easy video for you to see how us older Focus people do it. Same or similar for you... or what?

You can start a 2004 with a cut and non-programmed key IF you hold a programmed key "head-to-head" during start. So....

If I was you: I would buy another different or similar style key and do not cut it yet. Follow programming steps again and hold the uncut key head-to-head with the cut (non-programmed) key during programming. If the process is done correctly, the uncut key will program. This will prove the programming steps are being done proper/successfully AND prove the cut key is incompatible or dead.

If the 2015 does not do the head-to-head trick like my 2004 did, you will have to break down and cut-it, and re-try the programming. Buying/having a total of 4 PATS keys is not stupid. It is a great security blanket.

What im saying is since you didnt purchase through ford dealer they wont help.

That is not true, -or only true if the Service people are absolute total but-holes. They make money on both, the key and the programming. Plus, 99% of them want to make you happy when they can.

Moved to the MkIII section where you might find more info..

A number of key threads here for reference, but I haven't seen one for 15's yet (may or may not be differences).

 

Finally! I got the key working!

After try after try, I finally went to the second dealership on Sept 23 to have them program the key. They couldn't do it right then and said I need to make an appointment. "Ok, go ahead", I said... They didn't have an opening until Monday Oct 5! [80?]

Very well, ok...

In the mean time I got brave. After removing the battery cover, I noticed a small philips screw. Removed the screw and popped it apart.

I see a circuit board, the blade and flip/button/spring assembly. Hmm, I pull the circuit board out, and underneath, out falls a piece of plastic. "Whats this?", I thought.

Well, I started to reassemble it and wondered where that little piece of plastic belongs. I could not find any decent spot under the circuit board for it.

It dawned on me that it just might be the RF transponder chip. The only spot it fits comfortably is up by the flip-key assembly. That is NOT where it came from.

I reassembled the key and gave yet another whack and programming it.

Holy crap, it WORKED!!!

I now have my key working!

I suppose the trasponder position inside of the key is important! It NEEDS to be in the little nook next to the key flip assembly!

The only bad part is it rattles. I guess I need to disassemble it once again and insert a small piece of foam or something to cushion it.

Bothersome piece of plastic!

Nice!
Good work!

 

I'm looking at ordering this.... Does it still require the dealer to program the immo like on prior Foci with PATS?

 

As long as you have two already programmed keys you can program the new one.
