Hi,

I have two keys and was looking to program a third for my 2007 Ford Expedition. The first key will enter programming more, but the 2nd one refuses to. Any ideas on what I can do??

Thanks

 

I guess I don't understand your question completly? If the Expedition programming is like the F-150's all you have to do is put the first programmed key in - then go from the "on" to the off" position - then do the same with the second programmed key - then lastly put the "new" key and do the same. After that the last key should start the vehicle. I'd check in the owners manual for the actual directions, it is quite simple.

 

The 3rd key, is this from a locksmith, or from a dealer ?

Usually locksmiths clone the PATS info on the key, so it looks like the one you gave them to make the copy from.

If the new key is a clone, should be no need to program it.

If the 2nd key you are using to enter programming mode is a copy of the first, the truck will never enter programming mode, as you are trying to do this with 1 key ( 2nd key is a clone of the 1st ).

Little more info on the keys ( the 2 that are programmed, and what the 3rd key is ) are needed.

 

SSCULLY, do you know if a third key programmed by two "original" keys has a unique code? In other words, if you now have the two original keys and a third, home programmed key like I have, and if I lose one of the original keys, can I still program another spare with an original and my duplicate?

This was the hypothesis I was going on when I obtained and programmed the third key. I wonder if it was right?

Hope you had a good Christmas! We did.

Unless you have a "cloned" key, each key has its own unique RFID "serial" number.

The PATS system has the capacity (typically) to store eight unique code ID numbers.

It takes two unique, already programed ID numbers and an open memory slot in order to program a new unique ID number into the system.

Thanks, Steve. I think you said that having programmed a third key with two original keys, that I could lose one of the originals and still program a fourth with the two remaining ones, right?

I know you asked the other Steve, but yes this is correct. one factory key, and the 3rd key you programmed can program a 4th key, the 3rd and 4th key can program the 5th, etc.

The RFID tag on the key has to be programmed into the system with 2 pre existing keys. Which 2 it does not matter. Steve pointed out that with the default program, 8 keys can be added into the system, so the only time you would have to have a dealer or lock smith do anything is when you are out of key programming slots.
At this point the HEC needs to be erased and the first 2 keys put in ( and turned to on ) are the ones that the HEC stores, and fro here it looks like the factory run again.

 

This is what I've done for the last four F-150's we've owned. I always buy two spare keys the day the truck comes home, have them cut to the OEM key and then program them. So, now there's a total of four keys that work in the locks and start the truck. I take the two keys that came with the truck, put them on a key ring and place them in my fire safe. Now, the copies go on our key chains to be used every day. This is only from experience of having to pay top dollar to have original keys re-programmed. Never again. It's a small price to pay (for the spare keys) for piece of mind!

Thanks to both Steve's! It's good to find out I made a wise decision when I learned about PATS keys. And, Steve1, (SSCULLY) I sort of wondered what happened after 8 keys had been programmed - thanks!

Happy New Year to you both!
