Ford Focus MK1 - Brief Overview of Keys, Immobiliser & Programming 

Thanks I found this video helpful as I recently bought a Focus and two of the central locking microswitches on the key fob don't work. I bought a new 3-button key and programmed the central locking on th new key using your video. What I didn't fully appreciate is the procedure only fixes the central locking, not the engine immobilser, so the new key won't start the car. Just want to stress this point for anyone else who might think the "turn the key four times" process will mean your new key starts the car, as it won't.

I did it with a Ford Mondeo key after a battery change and the key works perfectly again after the first try programming. Thanks for this video 👍

I just program the key fob for a ford fiesta 2011 and it work perfectly fine with this instructions.

This is interesting matter! My 1.6 has only one key (with fob). My scrap 1.4 has three original keys: two with the fob and one plain key. All three have an immobilizer chip. I'm planning on switching the whole lot over. Cylinders and GEM. From what I've read, the immobilizer chips need to be programmed into the ECU. PS; It passed MOT with zero remarks! And Ford still has a small stock of those vacuum-lines. €38 VAT included.

My key locks and unlocks the car but it doesn’t start the car. I have to use my spare key to start. Does it mean it is already programmed or if I re-programme would it start?

Hello, i did it a few years ago, but now, after no longer being able to open the doors with remote control, I can't get the beep, I've tried every way, I even disconnected the battery for 1 day. Any ideas? What I can do? Thanks

Yes it dose work my circular board broken key still works

Hello! Thanks for the video, it worked first try! I was wondering if maybe you could tell me if the Focus MK1 has any other way to lock the doors, besides the key remote. Mine doesn't seem to have in the console a dedicated button for this. Thanks!

I did this and now my key won’t even start the car, luckily I have a spare key but it doesn’t have any of the locking functions on it. I noticed my key wouldn’t lock or unlock the car, so we got a new shell and tried to connect it. Made the beep noise but still didn’t lock or unlock and now won’t even start the engine. Anyone have any idea what’s happened here?

Does the immobilizer work after you program the key yourself like you did in the video?

On my Mk1 if you use the key on passenger door, all doors will lock and unlock but with drivers door key all doors work except the passenger, same with the fob. If passenger door is not locked from the inside then using fob or drivers door key the rears and drivers lock and unlock straight away. I've cleaned the door connector looms. Not sure if the problem is in the drivers door actuator or the passenger, any ideas?

My car only came with one key. Obviously I’d like a spare but my local Ford dealer told me they are the only ones who could program me a new one (I’m sceptical!). He quoted me over £300 for the privilege. Anyone else had a similar situation?
