Lab LMD3N1 – Frequently Asked Questions

1) Will the LAB LMD3N1 Mini Dur-X pin kit rekey Kwikset, Schlage and Weiser cylinders?
That's exactly what the LMD3N1 covers. It's a 3-in-1 kit carrying only the pin sizes and springs needed to re-pin Kwikset, Schlage and Weiser cylinders, with a location chart telling you which pocket goes with which brand. If you service other manufacturers as well, this is the wrong kit for those, you'd want a universal kit instead.
2) What pin sizes and springs come in the LAB LMD3N1 pin kit?
The kit is laid out as 23 bottom pin sizes, 3 top pin sizes and 1 cylinder spring pocket, roughly 25 pins per pocket. The heavy bottom-pin count is what lets you bit a key for all three brands; the top pins are limited because standard rekeying of these cylinders doesn't change driver height.
3) How big is the LAB LMD3N1 pin kit case, and will it fit in a service van tool drawer?
Case measures 8 x 5 x 1-3/4 inches, which is the point of the Mini Dur-X format, it's a flat tray sized for a truck drawer or a service bag rather than a bench box. The body is polyethylene with a platform insert and a reusable protective cover over the pockets, so pins stay in their pockets in a moving vehicle.
4) Do the pins in the LAB Mini Dur-X 3-in-1 kit use the .003 universal system?
Yes, the LMD3N1 is stocked with LAB .003 universal pins, so refills come out of the same .003 increment system rather than brand-specific pin stock. If your bench already runs LAB .003, this kit refills from what you have.
5) How do I know which pocket to pull from when rekeying with the LAB 3-in-1 Mini Dur-X kit?
The chart does the work. Pins and chart are color-coded to each other, and the location chart is removable with bitting information printed on the reverse side, so you can pull it out, read the bitting for the brand you're working on, and pick the pocket by color. That's what makes this workable for a maintenance tech who rekeys occasionally rather than daily.
6) Does the LAB Mini Dur-X 3-in-1 kit include tools, or just pins?
Pins and springs only. Contents are 23 bottom pins, 3 top pins and 1 cylinder springs pocket in the tray. A follower, plug holder, tweezers and a key gauge are separate purchases, so if you're setting up a bench from scratch, order those alongside the kit.
7) Is the LAB LMD3N1 rekeying kit meant for commercial work or just residential locks?
LAB classes the LMD3N1 as commercial door hardware, and it's built for the volume side of that: property managers and MRO crews standardizing Kwikset, Schlage and Weiser cylinders across a building on turnover. It only holds the three-brand pin range though, so a locksmith carrying mixed high-security or interchangeable-core work needs broader stock alongside it.
