Went from This Key fob to....that

[Incognito27]

Well for my year of car there weren't any. it was snaps . But i think newer ones are behind the Ford Sticker

[qweesy]

Does anyone know if this style will work i like it better..... it says it wont fit but Im thinking cause of the PATS chip which ill take from my old key and put in this new Fob but says its fits 2005-2009 focus.

It doesn't seem like it would. The original key fob has a square with the buttons and contacts located in the corners. This other fob has 3 on the front and one on the side. You could really only tell if it would work if you saw the inside of it. There's a possibility that the new fob had it's own chip that has to be programmed and all you need is the transponder.

thats a vw/audi key. wont work. your ford chip will not fit in that like the other one will.

I have this exact style key. I had a ford dealership do all the dirty work but it worked fine for me.

if you got a different circuit board inside then you can get the dealership to reprogram it to the car

I bought one of these. Had the local hardware store cut it to match one of my keys. Followed the programming instructions in the owner's manual with my two other keys. Works like a charm. Keep it on the keychain that I keep the key to the wife's VW on. Works great for me. Would highly recommend. Oh, my car's an 07 focus. Even with the remote removed from the assembly, the car will still start - so it has a PATS chip in in.

There are a lot of Ford keys that can interchange with each other... The big difference is getting the right PATS chip. Older (00-05) Focus use a chip like a pill and was only shared with a couple cars like the Escapes (01-04) and Lincoln Ls (00-02). Other Ford vehicles use that style but a different coding to the pill

Older pats key with chip pulled out


Short of pulling the "pill" and taping it to your column or inside one of those larger body keys there isn't many options

If you have a newer focus (06-11) the chip is the same as every other car with that shape of key and even some with the square keys like an 06 Grand Marquis or a Town Car. The Integrated Fob keys out of cars like Fusion, Edge, 08up Escape etc. have the same key chip built in. This means you could program a Fusion style key to your car as well as some of the flip/blade keys you see. It seems like its a more poplar chip. Most fords use it from the 2000's on.

Newer "round" key


Fusion key


I broke apart one of the fob keys i got from the junk yard.



The integrated keys are like a fob and chip internal on the same board. The long skinny chip on the left is the PATS chip I believe. The chips in these will not work on the 05 and older cars but the Fob portion can still be programmed to your car and have one cut to match. I am probably going to stuff a pill from one of my keys into one and then program the fob to see if it will work.

The integrated keys are NOT screwed together... they are GLUED and not intended to be taken apart other than the back cover coming off to service the battery. The 2012 keys are also LASER cut like a VW key and you wont find a hardware store cutting those things. Even some dealers don't have the machines to do it seeing they can cost up to like $8000

IF you want a key fob that won't break get a billet aluminum one. No more broken busted keyring loop. Put it on a lanyard and swing it at someones head you'll get a nice goose egg!

UPR makes a couple

I'm thinking of doing this too, what are the chances of me messing this up somehow? (I do have bad luck sometimes)

Also, what is the quality of the fob?
