Ford Mondeo Flip key Repair 2010-2017

Okay, we’re finally fixing the flip key today. It’s for a Ford Mondeo 2012, and when you press the button, and that’s as far as it (the blade) goes. You have to pull it all the way out with your finger to get it out. A bit sad looking, and not very good, really.

So we’re going to show you how to swap it into this repair case. This is one that we’ve been sent by our postal customer. And this one springs out nice. We’re just going to swap the electronics over. The first thing you’ll need to do is get the key blade out, and we need to open the case, which is really straightforward.

Again, as always, these are our best friends.

These Circlip pliers are the best tool we have for the job.

Ford Mondeo Flip Key Repair Stage 1- Opening the key

These are unusual pliers, because when you squeeze the handle, the jaws open.

This is what we use to open up most keys. So you need to put the end of the pliers into the gap as shown.

Give it a squeeze. And that has opened up the key nice and easy. The key is only glued together, there are no screws or rivots.

Once it’s open, we don’t need these broken parts anymore.  Save the ring, to put into the new key.

Ford Mondeo Flip Key Repair Stage 2 – Remove the electronics

We’re going to take this electronics board out . So rather than trying to get a screwdriver in there and damage something, if you just turn it over and tap it, that will just come out nice and easy.

Let me show you something really important.

This part here is really important. It’s the aerial that allows the transponder to be seen by the car and it gets damaged. When this happens, your Ford Mondeo will stop starting, which is bad. We believe that in the next 3-5 years, this is going to be a big problem.

This is just because we’ve seen a similar system fail in the other manufacturers keys. Okay, so the new case has obviously got to come open. So once again, pliers in those and it should come open nice and easy. Open it up, and the little spring mechanism is going to come out. That’s no problem. We’ll just keep it all safe.

Next thing is to pop the circuit board into the new key case. That should just sit in there nicely.

Ford Mondeo Flip Key Repair Stage 3 – Swapping the blade?

Next, we’ve got the blade mechanism.

Firstly, this part here is different to this. It’s been made differently, so you can’t just put this old bit into a new case. It won’t work, okay? So forget about that. The next thing is: Can you take this blade out and put it into this key?

You might be able to, but the trouble is the little tail that’s in there, is different to the little tail on the end of this one. So if you want to put this old key blade into this new hinge mechanism, you’re going to need to file it down slightly and mess about.

We’re just going to cut this key, it’s just going to be no bother. But you can have a go at doing that if you want. To swap the blades you’ll need to knock out the pins from both.

KEY REPAIR WARNING  This is when most of the key repair projects fail. This is because, we see owners hitting hell out of the old and new cases, just trying to get the blade out. It’s easy to damage the new mechanism, or make the hole too big so that the old blade is wobbly. We think you should find someone to cut it. But that’s easy for us to say!

Ford Mondeo Flip Key Repair Stage 4 – Rebuilding new key

Okay, so the next thing is to build up the flip mechanism, and we just need to pop this flip button into the hinge hole. It’s just a little bit fiddly. Excuse the sight of my hands, I’ve been stripping locks today, and they’re a bit sore.

Okay, next thing is to pop the spring into the flip button. So it’s the end without the tail. That goes into there. Next thing we’re going to take the blade mechanism, and it needs to go onto this half of the repair key. This little spigot here lines up with that hole. So you’ve just got to bear with me while we line it up.

Okay, and then you have to remember that it’s going to flick clockwise, so you have to wind it anti-clockwise. So wind it around. Okay. So that’s all caught.

That’s all good, the next thing is we need to marry the two parts of the key case. It might be easier if you let the blade slightly out. That’s it, flick the blade out. Then give it a bit of a squeeze. Okay, now we’ve got that all together.

The blade folds over and flicks just fine, so that’s good. The only thing we have forgotten is this end here has a ring, and that should be through there. I’m just going to open it up quickly and put that on there.

So all I did there was I just opened it up slightly, and pushed the ring into there and the ring’s in there now.

Ford Mondeo Flip Key Repair Stage 5 – Fitting the key battery

The next thing is to put a battery in. I’ve got a Maxell 2032.

We’re going to slide it in, a bit fiddly. That end has to go in first, and then it disappears inside. Then don’t forget, we’ve got a little screw that needs to go into there, that’s going to keep the key together. Don’t have a screw loose. So let’s just screw that. I should have had a decent screwdriver, but anyway.

Okay, so that’s all good. The last thing is these clips need to go into the key. Just pop that one in first. Okay, so that’s that cover on. Just by pushing each tab, eventually it clicks into place.

This video will help change the key battery.

Ford Mondeo Flip Key Repair Stage 6 – Cutting the key

The last thing now we need to do is cut this key blade. Okay, so if you can, get your key cut by someone that’s got a machine that can cut it to code, because you have a better finish and it means that it was as the original key was. Okay, so there we go. The blade has been cut, so that’s all good to go, same as the customer’s blade, and it flips out nice.

So with a three button Ford Mondeo key, you are good to go.
