MOST of such locks (called "cam lock") have a standardized mounting, 
although the "cam"/latch bar may differ.
You can replace the lock with one of your choice.
There are even COMBINATION cam locks, giving you the opportunity to forget 
the combination that you set, instead of losing the key.

With a larger mounting hole, you can get cam locks with Interchangeable 
Core, or with house-hey keyways to rekey to match your residence key.
