What you did was you turned off the feature (not all trims had MyKey). Which clears the MyKey restrictions for your specific key. If I understand correctly, once you turned it back on the restrictions remained removed?

All Focccus does is rewrite the Central Car Config which pushes options out to various modules. Thankfully Ford has moved away from this, instead storing the settings independently in each module in newer car lines.

I don't like CCC and try not to mess with it even with dealer tools. On later cars it's not a concern because you can only flub up the specific module you edit, not the whole car.
Correct. When switched to "0", MyKey was no longer an option & had no restrictions. Back to "1" and it added MyKey back as if it never had MyKey activated.

It would be nice to use that feature of the software myself, but I have 1 key and want the max of 4 so I need to have someone with the right equipment set me up properly and they want good money to do so. Also need to cut these security keys and that requires a specific milling machine.

Sigh... It's just money right?

The moment I say that I don't need more than 1 key is the day I'll regret saying it. I have a friend that works at a Ford Dealership so he gets a discounted price on the blade but the programming price doesn't very much.

FoCCCus doesn't do anything with the keys and their functionality. You're not able to add keys or remove keys.

All I did was switch a "1" to a "0" and it removed MyKey from the menus. I switched it back to "1" and MyKey was added back with no Admin functionality enabled, it had been disabled. Thus me not having to buy another key to just turn off the MyKey limitations.
Turns out the carkeysexpress company doesn't have the right OBDII computers that can access the titanium models. All he could do was cut my key blanks.

Do you think it's worth it to try this focccus program? How much are the parts?

I'm weighing my options. I have to get more keys added and I hate that ford is charging an arm and a leg to perform this service. IMO it should be a manufacturer lifetime freebie.

If you're talking the keyless access style, and with a Titanium you prob. are, the fancy fob programming is in another category.

Sounds like you just learned that.

From what im understanding your problem is. Is your mykey is set to a low speed. You can change all that if you plug your key where a normal key would go. Pop the cover off, then go into mykey settings. Youll find it.

Somehow my car has been set to the MyKey settings which limit speed to 80mph and alert you at 75mph. Not a huge deal except there's no hysteresis used. 75mph and I get an alert, slow to 74 and go back to 75, get another alert, on and on and on. Kind of annoying.

I only have one key for the car. Maybe it was like that when I bought it. Don't know, just been living with it for so long I've forgotten. The key I have apparently isn't an Admin key as it won't allow me to turn it off. So I guess I'm dealer bound? ...... which means I'm just living with it because ZERO chance I'm paying the dealer $100 for 30 seconds to clear it.
You might be able to clear it with focccus or even a tuner.
^^^

I used it to remove it. Worked fine. Still only have one key and no more Admin.
I'm buying the hacked obd2 module and will download the software. Any chance you can walk me through the process of disabling mykey? I'm having a tough time finding tutorials.

It's a push button ignition system, and I only was given one key fob when I bought the car. The other admin transponder is floating around the world somewhere, so I can't reset mykey without a hack or pay the dealership to do it.

What hacked OBD2 module? You don't need no "hacked" module.

I guess that'll work. I just used a cheapo $12 Bluetooth ELM327 that I bought back in 2013. I guess there is more safety behind a wired vs BT.
I wanted to use the system known to work properly. Many OBDII components apparently have the wrong hardware to access functions.

edited:

Finally got the software to work, and the hardware I bought did have about 3 failed attempts out of 4, but eventually it worked successfully and it didn't damage my BCM since the write to BCM is the final step in programming. Any failure aborts the write.

I'm so happy I could dance. The issues I had with FoCCCus not working were because I wasn't using the most updated version. It took some digging but I Was able to find FoCCCus 0.8.6 and with that and the OBDII I purchased I was able to access the system and learn how to TURN OFF MYKEY! I left it off. I don't want to accidentally turn it on again or my wife accidentally turn it on.

So happy right now. No more training wheels!

Since my car is a Titanium there really isn't much else I would ever mess with or try to turn on. I might turn off the seatbelt warning chime if I ever get annoyed by it. Otherwise my car is fairly well decked out.

The one other thing I want to do with this car is figure out how to add more key transponders to the vehicle, and delete the one that some random person has. I think I can do it with FORscan when I get a licensed code to unlock the features.

Working on tuning my engine/transmission now. That's going to take a while.

Thanks, If you check my most recent post it explains a few things.

Hello everyone, I wanted to post because I am so happy i finally DISABLED MYKEY! (WITH ONLY ONE KEY!!!)

I have to say, I would have never tried this or thought of this, if it wasn't for this Thread, and @novus in particular.
So thanks guys.

Okay, so i just bought a pre-owned 2016 Focus ST from a local Ford Dealership and it only came with one key. After a week of owning, I accidentally enabled the MyKey feature, not knowing what it actually was lol. (Big mistake)

So I searched everywhere for a way to disable this feature, preferably without having to buy a new key from the dealer.

Using the free Windows Application FoCCCus
**Message me for link**

And a USB corded OBD-II Scan Tool from amazon for $32

**Message me for link** or search Amazon for: ScanTool 425801 OBDLink SX USB: Professional OBD-II Scan Tool for Windows


1. So first things first, you need to install that application to your laptop.

2. If you purchased the same OBD Scan tool as i did, you will need to install it's drivers on to your computer. They can be found on the website listed on the instructions sheet it comes with ( You will ONLY need the drivers. Not the application the Scan tool is made for.)

3. Once you have the that done, your computer should be able to communicate with the OBD-II cord. Now you will go to your Focus, get in and close the door. DO NOT start car, just tap the ON button without pushing in the clutch or brake (Accessory Mode). Plug in your OBD-II to the car under the driver side dash and usb in to the computer. Load up the FoCCCus App.


Click the "Open" button


Now Click "Read from BCM"
There will be a progress bar on the bottom of the screen and the the FoCCCus app will read your car's ECU to get all the correct values.

4. Once done, I advise waiting about 30 seconds before unplugging the OBD-II from the car. Then turn off the car. Open and close the door to ensure it is off.

(Your car will start throwing you a number of random error codes on the screen, and give check engine light and every other kind of light. This is just part of the process and will need to be cleared later.)

5. Now you are ready for the last part. With all the value you uploaded into the FoCCCus app, scroll down to #239 MyKey. When i did it, the value was set to "2". You should click and change the value to "0".
Once you change it to "0" you can plug it back in to the car and follow the previous procedure (Put car in accessory mode). Then click "Write to BCM"
This will make you car have 0 MyKeys.
After, you will have repeat the process but this time changing the value of #239 to a "1" and rewrite it to the BCM, which will turn off The MyKey feature!
(WITH ONLY 1 KEY!!!)

To clear the error codes and check engine light afterwards, you can either use a Cobb access port, a SCT tuner, Forscan application, or have Autozone/Advanced Auto Parts do it for free.

Hope this helped!
I wanted to post this to back @novus 's claim. It really works! Even tho my dealer told me "it can't be done".

Why didn't you demand a second key when you bought the car?


I asked, and they told me the original owner only gave them the one key, and if they came across another Focus key they would call me and reprogram it to my car.
But you're right, i should have demanded. Lol oh well.

Now, that you've managed to clear it, do your self a favour and cut two extra keys. Good locksmiths can "clone your key" with the proper key coding machine so all the keys are indentified as the same key by the ecm/bcm etc... Just think what would happen if the lost the single key that you have....

Tried Focccus on 2013 SE, didn't work

Ok so I read this thread and was hoping this would work. But I tried it yesterday and it didn't. Here are the steps i did, please take a look and see if I did something wrong.

Background: 2013 Focus SE Hatch, bought for my daughter for college, only came with one key and it was a mykey. I purchased the elm hs/ms-can device from Amazon and downloaded Forscan and Focccus. Tried Forscan first on car to make sure things communicated and everything was fine.

Steps I did:

1, Pluged ELM device into obd port, turned key to on and loaded focccus. Device left in HS-CAN position.
2, Had focccus read BCM, saved baseline to file.
3, Changed mykey input from 2 to 0. Wrote to BCM.
4, Turned car off, waiting a min, disconnected elm and turned key back to on.
5, Turned car on, said "Normal mode" on screen but still recognized mykey key and still had limitations.
6, Checked settings and it still showed 1 mykey, 1 admin key. So based on setting it to 0, the BCM didn't remove the feature.
7, Plugged ELM back in and loaded Focccus, read BCM, confirmed it was set 0.
8, Set mykey flag to 1, wrote to BCM. Repeated step 4.
9, Same as step 5. No change.
10, Did step 7 again, loaded baseline bcm program and put back loaded back to BCM.



So does anyone see anything I did wrong? I was using this a trial run because I wanted to see if Focccus worked on her car because I want to do the fog lamp install because I have the fuse 75 with a 15 amp in it.

Looks to me like you followed the instructions perfect, I'm not expert on any of this, i just happened to get it to work and shared what i did.
Also my car is a 2015 Focus ST with keyless entry. Idk if that has anything to do with it, but i would try setting it to "2", then back to "0". And then to "1". A final time. Make sure you you are in accessory mode and wait in between reads and writes to the car. Good luck.
