Hi all, my focus has suddenly developed the fault of locking and unlocking whenever I'm in the car. I haven got a clue what's brought this on does anyone have any ideas what this could be many thanks. As its really annoying when it keeps locking me in all the time

i had this problem with my focus, and it was because the battery needed replacing in the key

i had the same problem witch was down to the c.l.m central locking modulater. its easy to replace i had 2 if i find them ill pm you and we will go from there
