My wife drives an '11 Edge that has an integrated key/fob combo that I really like since it's compact and is 1 less thing to carry in my pocket. Mine is an '04 FX4.

I did a little research and found some on eBay and amazon for under $20, but the reviews are mixed. So I'm curious if anyone has had any success that can point me to a link of one you've used.

I currently only have 1 key and 2 fobs, but noticed some of the descriptions say you need 2 of each to program them without having to go to a locksmith or dealer.

I'd prefer the flip key style to maximize compactness, but the standard key style with the integrated fob would suffice.


Thanks in advance!

Tough to tell. I had a flip out key in my 02 that worked just fine. I tried one of these in my 07 and the chip would not program to the truck. You WILL need TWO keys to program yourself or else pay a dealer or locksmith.

I needed a 40bit transponder key chip for my 06 Lincoln Mark LT .. an 80bit chip wont work

I bought one of those flip switchblade type 2 button keys on ebay for $20 however it came with an 80bit transponder chip. I couldnt figure out why it wasnt able to program until I came across a site mentioning that older years like ours required a 40bit chip. I then purchased a 40bit chip on ebay for $3

As mentioned above, you will need 2 original keys aswell

Thanks for the info. How can I tell if my key is the 40 or 80hz?

If its an aftermarket ebay key there is a small little square that goes inside the fob. I couldnt see any numbering/indication on it that determines what Bit it is. Thats why I thought id try my luck and bought a 40bit chip from an ebay seller for a few bucks.

Look at your OEM key, there will be a marking stamped on the key:

S keys are Ford old PATS (passive aint-theft system) 40 bit encryption, the newer SA is an 80 bit encrytion

Were 80s and 40s both used in 04?

I think the 80bit started in 09

My 07 has an SA on it.

BadFish523 - That makes sense as I've seen Mark LT keys with SA .. Must have started in the 07's

My 06 has an S on the original Key .. im assuming the OP will have an S aswell

Appreciate all the info.

How come you need two factory keys to do your own coding of additional keys?

If I have two non-factory programmed keys would I still be able to self program one of those key/fob combo units?

Are they pretty easy to program?
