Not easy i'm afraid, i've just done the wifes!
You have to take the interior door trim off first, remove the plastic cover from the locking mech, tricky if its a back door!
Get your self a good light so you can see what you are doing and be prepared to fiddle for 5 hours! i took the opposite lock off so i could understand how it worked and what part operated what and it was more a stroke of luck that when i hit it with a screw driver and hammer it opened! remember if your child lock is on you will have to trying the door with the outside handle.
Also a new lock is around £90..........get one from a breakers for around £20-£25
