Hello,

I have changed the battery in my ford fiesta key, now it wont work at all. I have tried the process in the manual ( turning from position 0 to 2 four times within 6 seconds and pressing a button). When i do this, there is a beep after the 4 turns, but no conformation beep when i press a button on the key.

Could anyone help?

When you say "won't work at all" do you mean for manually opening the doors/starting the engine? If so it sounds like you've managed to cancel the keycode on the key, have you a spare working key that you can recode it with? The instructions will be in the service manual.

Next time u see an RAC or AA man at side of the road stop n ask him. That's what I did out of desperation when mine was playing up and I'd lost my rag. He just fiddled with it for 2 mins (the key!) and that was it. They are all great guys n I'm sure would be happy to help. Especially if you send a female!

I agree with strawdog, sounds like it needs recoding by Ford. Could be expensive, try going in today and trying some Christmas sob story

sorry I should of been more clear, I mean the remote doesnt work at all anymore, i.e. none of the buttons work.

the key still starts the car and opens doors.

Have you tried cleaning the contacts in the remote, isopropyl alcohol (best things are those little swabs the doctors use to clean injection sites) sounds silly I know but mine went dead on my old jeep and that did the trick

I think the technical name is cotton buds.

Nope they're little squares of a cotton type stuff, cotton buds tend to leave fibres behind

It's not the keycode then which points to either the transmitter/receiver or the contacts within the key fob. Before you needed to replace the old battery did performance decrease over time (required multiple presses, angling/moving nearer for it to work, etc.)? This is the normal behaviour when the battery starts running low, if it didn't do this then it's likely a fault rather than a dead battery.

First steps would be to clean the contacts, as advised above, and check your service manual for where the receiver is inside the car to ensure there is nothing blocking the signal, also check whether your car uses infrared or radio for remote locking (if the key has a small glass eye on the fob it's IR). If your car uses IR make sure there's nothing blocking line of sight between the key and receiver (sticker/dirt on the fob, something hanging inside the car, etc.).

I think you will find they are generally called Sterets,have you ever seen a doctor using a cotton bud to sterilise skin before an injection?? :p

Try re syncing the remote , put the key in the ignition then turn key so the lights come on but don't start it , then keep one of the buttons on the key pressed and the door looks should go up or down , then take key out and try key fob , worked on my old Astra might work on your ford , worth a try

Programming procedure-



1. Insert Key and turn to II, then Turn Key from II to I and back to II four times within 3 seconds

2. The PATS LED (Flashing immobiliser light) should light up to denote that the programming phase is unlocked. Turn Key to Position 0.

3. Press the Unlock button and keep it pressed until the PATS LED flashes 4 times.

4. Turn to II and back to 0 to end.

I am having the same problem on my 06 focus, changed the battery as it had been playing up over time, since then tried all the different sequences but cannot get the fob to work. The chime will sound to indicate it is in learning mode, but does not want to recognise the key fob. Any sensible suggestions appreciated.

Absolutely - worked like a charm for me too! (08 Fiesta, mk 6 facelift). The immobiliser light didn't come on and stay on mine though - instead, it made the sound like you've turned the ignition off and left your lights on when you open your door. Apart from that though, everything else worked exactly as stated. Thanks for saving me some time and cash guys!
