Sargent 10-3036 – Frequently Asked Questions

1) What exactly is the Sargent 10-3036, and does it come with trim or a cylinder?
The 10-3036 is the mortise lock body (the case and its internal mechanism) for Sargent 10-Line locks, built for the 38 function and set up to take a large format interchangeable core. It is sold as a replacement lock case only, so levers, roses, escutcheons, and the LFIC cylinder itself are separate items you reuse from the existing lock or order alongside it.
2) Will a Sargent 10-3036 lock body work in my 8200 or 7800 series mortise lock?
No. The 10-3036 case is built for the Sargent 10-Line mortise family only. Sargent's other mortise lines use their own case assemblies, so pulling a 10-Line body into a different series is not a swap. Check the number stamped on the existing case or the lock's original 10-Line designation before ordering.
3) My Sargent 10-Line lock has a standard mortise cylinder, not an interchangeable core. Is this the right case?
Not likely. The 10-3036 is the LFIC configuration, meaning it is set up to accept a large format interchangeable core. If the door currently uses a conventional threaded mortise cylinder, you need the conventional-cylinder version of the 10-Line case, or you convert the opening over to LFIC cores and rekey the building's master system to match.
4) What is the 38 function on a Sargent 10-Line mortise lock?
The 38 is the function code that defines how that lock case behaves, which levers are free, which is locked, and how the cylinder controls it. The 10-3036 is built specifically to the 38 function, so it has to match the function of the lock you are servicing. If the existing case is stamped a different function number, this body will change how the door operates even though it physically fits the same 10-Line prep.
5) Can I replace just the lock case instead of the whole mortise lock?
Yes, that is the point of the 10-3036. When the mechanism inside the case fails but the trim, cylinder, and door prep are fine, you drop in the replacement body and reuse everything else. It saves recutting the mortise pocket and keeps the existing lever design matched to the rest of the openings.
6) Does using an LFIC lock body let me rekey doors without pulling the lock apart?
Yes. Because the 10-3036 takes a large format interchangeable core, a control key removes and replaces the core at the door, so rekeying a suite or turning over a tenant does not mean disassembling the lock or taking it off the door. That is why facilities standardize on LFIC across a building's master key system.
7) Is the Sargent 10-3036 suitable for high traffic commercial doors, or is it a light duty part?
It is a commercial part, built for the 10-Line mortise locks that go on office, school, healthcare, government, and multi-tenant openings. This is not residential hardware, and it is not intended for tubular or cylindrical locksets.
8) Is this a genuine Sargent part or an aftermarket lock case?
It is a genuine Sargent component, model 10-3036, made for the 10-Line system. For a facility standardized on Sargent, that matters because the case has to index correctly with the original trim, spindle, and core.
