im not 100% what this lock is, but if its anything like the cash boxes we have in the UK, the locks are wafer locks, these are fairly easy to pick, but it sounds as though yours is broken inside.
if it is a wafer lock, you unscrew a screw at the back of the lock, take off the clip that actually locks the lid in place along with any washers, then put your key in and the lock barrel should pull out of the front. if it doesnt, you may have to take off a very small round clip holding it in place. it is a fairly simple process if it is the right type of lock. you can then either take it to a locksmith to get it repaired of buy another lock the same to replace it. ebay often has a lot of locks like it.
