Question: Can i replace the mail box lock?
Document: We have had this box for more than 5 years. It has been pried at on the top and bottom doors and someone has tried several times to break the lock. I had to replace the lock a few months ago - it was easy and cheap. They sell locks at Home Depot that work great. My only complaint is that it does leak. I have had to install it out of level a bit, dipped down in front, so the rain doesn't come in. It fits small packages, too!
Bought this with the 4" square Architectural Mailboxes post, which works perfectly with this box.Fit and finish is really nice. No rough surfaces or sharp edges, and the paint job looks great. It feels quite sturdy, even the flag.My only suggestion for an improvement is to replace the hex bolts used to secure the box with carriage bolts, and add lock washers to the installation.
This mailbox is large and sturdy. I have no complaints. I installed it in about 45 minutes on a standard post, but I did have to go to Lowe's to get the correct hardware and I made my own mounting bracket out of wood. This was due to the strange post I have and I didn't want to replace it.The lock is pretty secure as far as I can tell.

This mailbox was easily broken into by thieves with what appears to be a simple screwdriver. They popped it right open without damaging the lock. Now the box is bent and doesn't close completely allowing water to damage mail.
I choose a large mail box so I could receive packages. But the way this one is set up you can only get very small packages in it. It would be fine if you receive a lot of mail. Hopefully the lock on it will keep people from steeling our mail!
I purchased this as I am having to replace my super dupervery expensive deluxe WHITEHALL Estate box (the mailbox door hinges fell apart...)  The box looks sleek and modern- and I have mounted artwork on the sides of it. My neighbors all like it a lot!AND-  It has a piano hinge so it won't fall apart like the WHITEHALL hinges... which have two tiny wires about the size of a paperclip holding a heavy door in place.
This is a good product. I needed a mailbox that would lock, and eliminate anyone from being able to reach in and grab waiting mail. The box is neat--the mail carrier opens the top of box by pulling down the handle. There is a angled panel the mail is placed on, and when the box is closed, the panel angles downward and the mail drops into the secure portion in the bottom of the box.
If you have zero tolerance for mail theft it will cost you $200 plus for a secure mailbox. Try Fort Knox boxes. If you don't believe me buy this box and try and pry it open with a large screwdriver or wonder bar. You'll realize the only reason to lock it is to keep the door from flapping in the wind.Search "Oasis Jr Locking Mailbox Vulnerable to Fishing and Prying " on youtube1:47 well spent
When it came time to replace my old mailbox, I was looking for something a little larger and more durable. Both of my wishes were met with this mailbox. A stonemason created the new case for the mailbox and it fits beautifully and looks good. It is secure and seems to protect my mail especially with the locking feature.
Answer: yes
