Hi, how on earth do you change the locks on a coupe door??? Have bought a door and need to change the barrel to fit my cars key. Any help please!!!1

If it's like my Punto there's a slide in locking "u piece" of metal that holds the barrel onto the door skin.

Thanks, all done. I found it easier to take off the door handle and replace the complete piece. The hardest part was locating the bolts for the handle. You have to take out the window guide and take out the 2 bolts. Then disconnect the catch/lock push rods and then job done...Took about 20 mins.
