I have a few problems with my focus, it's a 2000 1.6 Zetec problems are:

• While driving the car the central locking has a habit of flicking on and off, most of the time it doesn't succesfully lock it just seems to make a sound
• At idle there is a ticking sound, I'm not sure if it is injector noise, it isn't that loud, just something I want to know about
• The locking wheel nut key is missing (auction car) I have read that ford have a set of master keys, but is this type of locking key original ford or aftermarket

Thanks for your help


Edit:

Also the the central locking fob doesn't work, I think there might be a piece missing out of the fob for the positive battery connection, Anyone got a fob for reference?
