you stiil have to use a plug follower to put them back in (top pins and springs) if you take a look at a plug follower they have a groove cut out at one end,which then you can insert the follower into the shell of the lock,line the groove so it's vertical with the first hole,drop your spring in and then your pin,pushdown on pin with small screwdriver and gently push the follower over the hole thus trapping it in.then go onto the next ect ect.
hope that was'nt to confusing (or was it!!!!!

)
