I have a Brinks padlock model TSA007 it has a keyhole but it didnt come with a key, can i purchase a key just for backup?

Sorry we can't help with that kind of problem at this website, call a locksmith is my only suggestion

either buy a set of locks that are keyed alike a few places carry bulk locks --or buy locks that can be keyed to what ever key you want call a locksmith and ask for places to buy bulk verses interchangeable tumbler locks

If you have both pieces of the broken key, it can be duplicated.

I did not find that key code listed for Brinks, but perhaps you can get one from Brinks. A locksmith can make a key, check the cost. You really don't want to pay more than the cost of replacing the lock.

Do you mean duplicates of keys or do you have no working keys?

I think a local locksmith would either be able to make the keys or give you a reason why keys can not be made for your locks. Look up 'locksmith' in your local yellow pages.

Any locksmith should be able to cut you replacement keys. I cannot verify it, but the key code is likely the actual cuts of the key, and so it will be easy to cut them. If not, the locksmith may have to use the code to look up the cuts, which may cost a bit more. Even then, it will still likely be cheaper than trying to have them mailed from the manufacturer.

MINE IS ALSO A 50MM , NO.3979931

the lock combination is not working anymore, I can not open the lock, how I can reset the new combination
