Probably best to go with a Master brass bodied padlock such as No140, or a rekeyable Master such as 220/230 as suggested previously. No140 is a step up from normal pins and is only a four pin lock. Rekeyable Master 220/230 is a little trickier - 5 pin with (normally) 4 spool top pins. The earlier 220/230's had no top spools to my knowledge, so make sure you get a current model.

If it ain't broke.....pull it down and see how it works anyway!
