Remote Spare Key Reprogramming

[sandyman]

Can anyone help. I have a 2010 Focus and changed the remote key battery. It didn't work initially but after following guide on reprogramming on youtube(moving key in position 2 to 1 in ignition four times) I thought I had solved the problem as it worked immediately. However, my wife's spare remote key no longer worked. I reprogrammed it using the same technique and it worked but then my key no longer worked!

My problem is now I can only have one key programmed to operate the car at the one time.

Any suggestions?

thanks

you have to do both at the same time

I've just tried reprogramming the one immediately after the other but it still only works for the last one reprogrammed

Thanks anyway

when you start the first programing press the buttons on both keys that's it done

thanks a lot dezwez. Both keys working fine now, much appreciated. Glad I joined the forum!
