Ford Focus remote central locking - Philj
My wife's Focus has developed an intermittant problem with the central locking. Sometimes it works, sometimes total silence.

New battery fitted to Key - no improvement.

Is this likely to be a faulty keyfob? Or prob with car?

Try using the key in the door lock for a bit, and see if the problem still occurs.

You can still get the (2 press on key fob) dead-lock function to work by turning to open and then lock with-in 2 secs...confirmed by the indicators flashing twice...and also the window function by holding the key in either position for a few secs.

Assuming this is the previous version Focus of course...
