So im in charge of getting the mail at my office. And you'd think it would be hard to mess up such a menial task, but I lost the key somehow to our P.O. box-style mailbox. Bought this and replaced the lock and put the key in the office. No one has noticed yet and the lock looks pretty similar to the original.Install was easy and lock/key function how you'd expect.

The mailbox lock at my rental property was broken.This lock very simlar to the lock that is already on the mailbox so I was hopeful that this new lock will work.This lock was very easy to install.The lock came with several latches of different sizes.I tried multiple latches and found the right one that fits.

Lots of options to install the lock, but the key is not smooth at all. I may try some graphite in there to make it more smooth.
