Hi unlisted iv got a about ten padlocks,no branders i call them and ones given to me by friends who lock their sheds and lose the keys

i always try to spp them not rake them,i got a kaba drawer lock i posted about thats my goal at the moment,i think im going the wrong way as to learning because im trying 6pinned union euros i got from scrap doors on the building site and the kaba before i can pop the padlocks every time,im dying to ask what brand of rekeyable lock to get in the uk so i keep looking through the posts to find out.
if everyone who tried something new liked it but didnt bother telling anyone else there would never be anything new to try...
