Product Description

Each lock has a unique key (KD).

Questions & Answers

What is the number of keys included with each lock?

Each lock comes with two keys.

For the C9100, do you have a blank key?

The most likely blank is D4301, but the determining factor is which way the keyway groove faces. The other challenge is duplicating the key itself; if you take the original to Lowes, they will most likely try to make a copy on a NA 15 blank, but because the cuts on the key are so small, you will get a key that works but never as good as the original; I literally replace hundreds of these a year and when people want an extra copy, I make them.

Is there a set of keys included?

Yes, each lock comes with its own set of keys.

This new lock will be used to replace the old one. Is it necessary to get permission from the USPS for a CBU unit?

I'm not aware of anything because I own the mailboxes and the post office has the key to the back. I frequently ask the mailman to open the back door so I can remove the nut from the lock and replace it. Otherwise, I'll have to drill the lock out, which will be difficult due to the hardness of the steel.

STOPPING THE SCALPING IS NOT AN OPTION! The product is fantastic, but I'd like to get people on board with STOPPING the SCALPING that Amazon allows
5/5

Products are literally stolen from online shopping carts and relisted at three times their original price!.

It's a good deal and it's simple to set up
5/5

A perfect replacement that is well-made and simple to install. It was also delivered ahead of schedule, which was a bonus. It doesn't come with a hasp, but since you'll be removing the old one to install the new one (which was never damaged), it'll be installed in no time. Make sure the key turns in the right direction!.

It's simple to set up and does its job
5/5

These are the mailboxes that I use for my HOA. They're reasonably priced and look exactly like the ones that came with the cluster mailboxes.

I looked in local supply stores for these locks and found them to be perfect
5/5

Buying one at a time is way too expensive; these fit mailbox doors perfectly and take only five minutes to replace.

Our requirements must be met
5/5

As promised, the order was shipped and received on time. The locks function exactly as they should. We've ordered these a few times now, and each time the service has been excellent and the locks have lived up to our expectations. We have a large townhouse complex where we are forced to change the locks more frequently than we would like.

It's great, but it needs some direction
4/5

They just don't come with any instructions on how to put them together.

Locks are designed to fit precisely into mailbox lock openings and to work with existing locks
4/5

The locks fit perfectly into the mailbox lock opening and make use of the old lock's existing cam. There is no need to file the lock to make it fit.
