Hi

I've a 2004 Fiesta LX with only one key.

I changed the battery yesterday and since then the remote unlock doesn't work. The key will open the door and start the car, so Im guessing the chip is still ok - its never given problems unlocking remotely before.

I've tried loads of online suggestions, key to II then I four times then hold the unlock etc but all to no avail. I get a beep which I believe indicates learning mode, but that's as far as I get.

Anyone got any other ideas please

Thanks
