Sargent 439 – Frequently Asked Questions
1) Will the Sargent 439 construction keying kit work on Signature and XC cylinders, or only conventional Sargent cylinders?
All three. The 439 lost ball kit handles Sargent conventional, Signature and XC cylinders, so a locksmith carrying one kit can construction-key a job that mixes those cylinder lines. What it will not do is cross brands: it is built around the Sargent lost ball method and the Sargent cylinder body, so Schlage, Best or Corbin Russwin cylinders on the same project need their own construction keying approach.
2) What is in the Sargent 439 keying kit, and do I need to buy anything else to construction key cylinders in the field?
The 439 kit ships with the drilling block, drill bit, knurled pin, hex key, and the collar and set screw assembly, plus 500 replacement balls under P/N 13-1103. That is the full tool set for the lost ball procedure, so nothing further is required beyond the cylinders themselves and the keys being cut for the job. The 500 ball count is what makes it a project kit rather than a one-off: each cylinder consumes a ball, so the pack covers a large construction phase before a refill is needed.
3) How does the Sargent lost ball construction keying system actually work on a job site?
A steel ball is placed in a drilled passage in the cylinder so the contractor's construction key operates the lock during the build. When the permanent key is first turned, the ball drops out of the way and is lost inside the cylinder, and the construction key stops working from that point on. No return trip, no re-pinning, no factory return. That is why the 439 kit includes the drilling block and drill bit: the ball passage is created in the field with those tools, not ordered from the factory.
4) Should I use lost ball construction keying or a construction master key on a new commercial build?
Lost ball suits a job where you want the contractor's key voided automatically and permanently the moment each tenant or owner key is used, with no locksmith visit at turnover. A construction master key pinned into the cylinder instead needs the cylinders re-keyed or the construction combination removed at handover, which is a second labor pass across every opening. On a large phased project, the 439 kit's 500 ball supply is sized for the first approach. On a small job of a handful of doors, the drilling step may cost more time than it saves.
5) Do I have to buy a whole new Sargent 439 kit when I run out of construction keying balls?
No. The balls are a stocked consumable under Sargent P/N 13-1103, so once the tools from the 439 kit are in the van, refills are the only recurring item. The kit ships with 500 of them. The drilling block, bit, knurled pin, hex key and collar assembly are reusable across jobs.
6) Is the Sargent 439 kit for commercial work, and what kind of projects is it sized for?
Commercial, and sized for volume. Sargent lists the 439 as commercial door hardware, and the 500 ball supply points it at multi-opening work: office and government buildings, schools and healthcare renovations, industrial facilities, and multi-tenant residential. A single-door replacement does not need it. A general contractor turning over a floor or a building of Sargent cylinders does.
7) Which Sargent key system does the 439 construction keying kit belong to?
The 439 sits in the Sargent conventional key system, and it works on conventional cylinders as well as Signature and XC. If a facility is standardized on a Sargent conventional keyway, the kit drops straight into that program, and the construction phase can run on the same cylinders that will carry the permanent keying afterward.
