S-Max replacement key.

Hi,

I'm trying to sort a replacement second key for my 2012 S-Max 2.0 Titanium X. Basically the original second got very wet when climbing a mountain recently and now does not work (well it does, but it's having some very strange issues - like dropping all windows when you press a button and randomly reporgramming the 2 push function etc.). 

Anyway, have FORScan, have the reader/programmer module (USB), have a laptop, looking at blanks and slightly confused. I have the push button start model, so have one working key, one not working key, and blank keys are confusing me. I know I need to backup, wipe both keys and re-program. Got instructions. But I have two issues - one the blank key - according to Ebay, there are ones with and without an additional OEM chip - which should I go for? How can I tell? Also these are 4D63 fobs - not sure how to tell what my current key fobs are - does anyone know a way, and whether I can identify whether I need the additional OEM chip of not please? Thanks. Ebay links below:

Any help greatly appreciated please.

Hello @SiW0020 The chip in question is the Passive Transponder. It is quicker and easier if you can just transfer it from your old keyfob to the new one.

If you post a picture of the circuit board of your keyfob (both sides) then I can probably tell you which type you have,

Thank you, I will post in the morning. 

The circuit board was all wet when I took the key apart to work out what was happening, absolutely filled with water. So looks like it's 'toast' - tried drying and PCB cleaner, but no joy. 

TIA,

SW

Hi, I would use this one on eBay - Please understand this is only a suggestion and I can not guarantee 100% that it will be ok.

The transponder chip is not on your circuit board so it must be moulded in to the back cover of your keyfob. Swaping the back cover of your old keyfob over should mean there will be no need to programme the security system. you will of course still have to programme the lock/unlock buttons.

Excellent 😀 👍

Thats the transponder chip. All you need to do is transfer that to the new keyfob 🙂

You will still need to programme up the lock / unlock buttons but thats easy !!

Brilliant. Okay I'll work out how to do that next then. I have a key fob, do I still need the one you recommend please?

Hi, so after a load of back and forth ordered a different key - basically the one from the link above ‘got lost in the post by royal mail’ then the seller cancelled the purchase!?!?!? Not being funny, but smell a rat there…..anyway got a second, but can’t get it programmed for the car. Any idea on process anyone please? Believe I can do via some process of pressing start/stop button so many times but no joy. Swapped battery in new fob, but nothing so far…..or have got a rubbish Chinese knock off? Ta……https://www.ebay.co.uk/itm/124357524385

 

regards,

Si

Yes I did, my chip doesn't seem to show the contacts though, so may be a bit mucky....may try wiping some very fine sandpaper over just to expose contacts.

Shame they don't put an LED in the key fob so you can at least confirm it's working!!

Strange then unless the circuit board does not work - does anyone know the process for getting the car to initiate the programming mode? I can see for the key operated vehicles this is turning 0 <> 1 so many times in so many seconds, but can't find ones for push start.

You should be able to use FORScan to programme the remote operation buttons.

OR option 1:

  1. Shut the car doors, then open the driver-side door. Press the UNLOCK button the driver-side door.
  2. Now, turn the ignition from OFF to RUN 8 times. ...
  3. Press any button on the Ford remote to program it. ...
  4. Have more than one key fob? ...
  5. Lastly, turn the ignition OFF.

OR option 2:

  1. STEP 1-Turn on the ignition. You should sit in the driver's seat with both the ignition key and the key fob with all doors closed. ...
  2. STEP 2-Press the lock button. ...
  3. STEP 3-Turn off the ignition. ...
  4. STEP 4-Repeat the process with other key fobs. ...
  5. STEP 5-Restart the process.

Hi there, tried this, still no joy. The push button system doesnt' enter the programming mode, not sure why. I will try the Forscan software this weekend.
