A combination lock is effective because the combination is theoretically known only to the owner of the lock, or whoever has permission to gain access. Some types of combination locks can have the access code set up by the owner, which makes them unique. There's really only one drawback: what if you need to change the combination? That could be a problem if the lock is on an item you desperately need to get at, or on the entrance to a location you've got to get into. The good news is, in the case of most combination locks there is a solution to this problem.
Resettable combination locks give owners the ability to change the sequence of numbers required to open the device. Not all combination locks are resettable, though; be sure to check whether yours is when you begin using it. In order to reset a combination lock, consult the manual or directions that came with the lock.
Thanks and Regards,
