afternoon all

Please help. if any ideas.

i have a 06 plate focus with the rounded 3 button key fob.

when trying to unlock the car it takes a few times of pressing the button before anything happens and when the doors sound like they unlock only the drive door acutally unlocks. i then have to press the unlock button a few more times to get the other doors to unlock.

also have the issue when locking the doors but they do all lock together eventually.

i have chaged the battery in the fob but still the same problem.

does it mean i need a new fob? are just reprogram the key? are maybe somethin else?

thanks
