Using Kwikset Keys to Match Your Weiser Locks

Posted by Brian Hermansen on

You've just stumbled across The Key Armory and you are fascinated by the gorgeous designs, the shiny detail and the ability to choose either a Kwisket or Schlage, one of which will SURELY fit your lock! Right?

But wait! You gaze across the room to where your keys dangle from a dusty hanger. You glance back at The Key Armory's prepared Keyway Reference Guide. From this distance, it doesn't look like the head of your key matches EITHER of the pre-determined keyways. You move in to get a closer look, the square head coming cleanly into your view.

And then you see it - the dreaded "67" engraved into the side of your key beneath the bolded logo "Weiser" - but The Key Armory doesn't carry Weiser keys! How could this be? Where did you go wrong? 

You drop to your knees, holding back the rage - nay, the hatred - you suddenly feel towards your keyring. And then you hear it - a soft chime. A notification from The Key Armory, leading you to their newest blog post - Using Kwikset Keys to Match Your Weiser Locks. You click the link as you dab your tears away with a cloth and begin to read...


Here at The Key Armory, we carry two different key ways, or shapes, to match most locks throughout the United States. These same key ways, Kwikset and Schlage, actually work in several other countries, as well, though they are less common.

Check out the quick Keyway Guide that is shown on all of our product images below:

As you can see, most key ways can instantly be determined by the shape of the head. If your key looks similar to the key on the left, a Kwikset, then our Kwikset option will match KW1, KW10, 66, 6, 65, & 5 keys (these numbers can often be found engraved into the head of your key). If your key looks more similar to the key on the right, a Schlage, then our Schlage option will match SC1, 68 and C keys!

However, there is a third key that is fairly common in the states - this is the Weiser, which is most commonly sold as a 67 or WR5. Weiser keys are generally square, and one of the engravings can normally be found on the head of the key. I recently moved into my new place and found that the existing locks were Weiser, shown below:

Often times, and the same goes for Kwikset and Schlage keys, you can find the type of key engraved into your lock:

Up to this point, I had HEARD that our Kwikset key way would fit into a Weiser lock (though the opposite cannot be said, meaning that Kwisket key should work in a Weiser lock, but a Weiser key will not work in a Kwikset lock). 

With little hope, I chose one of my favorite keys, The King's Blade, in a KW1 key way and headed to my local Home Depot. The nice lady at the cutting machine took a look at my keys and said, "I don't think we can duplicate this." I told her that I understand that if the key is duplicated incorrectly, I won't blame them and that I would assume full responsibility for replacing the key (by the way, you can check out our Returns Policy here). She inserted the key with some heavy skepticism and ran the machine.

Once the machine spit out the freshly cut key, she held them both up and sighed. "I told you so," she said, handing them back to me. Disappointed, I looked down at the freshly cut King's Blade. When aligning the key tips, it appeared as though she were right - it almost looked as if the key hadn't been pushed in all the way, as the bottom of the King's Blade had an additional few millimeters of uncut space that couldn't be seen on the original key. See pictures below:

I returned home that day and nearly forgot about the incorrectly cut key. I hadn't really even given it too much thought, as it looked like it was, indeed, cut wrong. I dug for it for a moment, and then put it into the lock. After a moment of fiddling, I was shocked and delighted to find that the key actually DID work. I knew that in theory, it might, but it was great to actually feel it turn and see it unlock the door.

While my experience cutting the Weiser key may not reflect the experience of others, I can now say that I do know that it is possible. Since then, I have done some research and found that while it will usually work, it's not recommended by professional locksmiths. If you're worried about wearing down the locks or doing any type of damage, we highly recommend not using a Kwikset key way in your Weiser locks.

With all that said, we can confirm that a Kwikset key way will work in a Weiser lock. Due to it's nature, however, it's important to note that if you willingly purchase a Kwikset key way knowing that your key way is a Weiser WR5 or 67, we do not offer refunds or exchanges if it is cut incorrectly.
