Rated 5.0 out of 5.0 by Perfect replacement The lock set was the perfect replacement for my mail box lock. August 25, 2015
Rated 4.0 out of 5.0 by Mailbox lock Before I started working on Condos and apartments, I didn't know that this was a product sold at Home Depot. Within the last 2 years, I have purchased and installed approximately 10 replacement locks kits, largely due to lost keys. I have not had a single failure with any of Nickel Universal Mailbox Locks that I had installed. With this said, I have used these same lock kits on several different types of group or cluster mail boxes. And most importantly I have always been able to complete the installation using one of the several different lock latches supplied in the kit. It is very important for me to complete an proper installation, without having to run back and forth to the store for more parts. Because of the many types of mailbox door units out there, the Nickel Universal Mailbox Lock kit comes with an array of latches that you can easily attach for a perfect locking- fit. In addition, the full lock assembly and latch is easily installed into the door by slipping it into the door and then securing it in a one step, snap-in clip. The steel clip secures the lock to the door. This lock assembly is an easy install for a novice. Its also reliable and very inexpensive. August 11, 2015
Rated 3.0 out of 5.0 by universal mailbox lock Lock seems sturdy. Mailbox lock opening seems to vary depending on type of mailbox therefore installation is little more tricky...not as easy as some vidoes I've seen. But I did it!! May 12, 2015

Rated 3.0 out of 5.0 by Mailbox Lock Exactly the same as broken lock I replaced. Inserting key into lock isn't smooth so I imagine key will break in lock at some point, just like what happened with old lock ! April 8, 2015
Rated 5.0 out of 5.0 by What a relief! I lost my mailbox keys and panicked when USPS told me they would replace it for $85. After doing a lot of online research, I purchased this and did it myself. Our post lady was very helpful and my new lock works great. A little adjusting due to it not fully turning to the correct lock angle when initially installed, but it finally worked out. Glad I saved $80!!!! Remember, this unlocks counter clockwise. March 6, 2015
