Sargent 82-5434 – Frequently Asked Questions

1) What does the Sargent 82-5434 spring actually do inside the lock?
The 82-5434 is the guard bolt spring. It supplies the tension that pushes the guard bolt (the small auxiliary bolt that rides against the strike and deadlocks the latch) back out when the door opens. When that spring weakens or breaks, the guard bolt stops returning, the latch no longer deadlocks, and the lock feels sluggish. Replacing the spring restores the tension without touching the rest of the lock case.
2) Do I have to replace the whole Sargent lock if the guard bolt stopped springing back?
No. If the fault is the guard bolt losing tension, the 82-5434 spring is the serviceable part, and swapping it restores lock function without pulling the lockset off the door and buying a new one. For a property manager running a lot of Sargent openings, that is the difference between a parts order and a hardware replacement across the building.
3) Is the Sargent 82-5434 a genuine Sargent part or an aftermarket spring?
Genuine Sargent OEM. It is supplied under Sargent's own part number 82-5434 and built to Sargent's original specifications, so it drops into the guard bolt assembly it was made for rather than needing to be stretched, cut, or shimmed to fit.
4) Is the Sargent 82-5434 spring for commercial locks or will it fit a residential Sargent knob?
It is a commercial part. The 82-5434 is catalogued for Sargent commercial mechanical lock assemblies, so it belongs in commercial mortise and cylindrical lock service work rather than residential-grade hardware.
5) How do I make sure I am ordering the right Sargent spring for my lock?
Order by the Sargent part number stamped in the parts breakdown for your lock: 82-5434 is the guard bolt spring specifically, not the latch return or retractor spring. Sargent parts numbers are model-specific, so match the number on the exploded view for your lock series before ordering. Only the one SKU, 82-5434, is offered here, so there is no finish or size choice to make.
6) Will a Corbin Russwin lock part work in place of the Sargent 82-5434?
No. Sargent lock internals are not interchangeable with Corbin Russwin. A part like the Corbin Russwin Swivel Spindle Pin X Set Screw is a different component in a different lock platform (it is a spindle pin and set screw, listed for 1-3/4 inch doors), not a guard bolt spring. If your chassis is Sargent, stay with the Sargent 82-5434.
7) My lever is loose on the spindle, not the latch bolt. Which part do I need?
A lever that turns loose on the spindle is a spindle retention issue, which is what the Corbin Russwin 499F838 swivel spindle pin and set screw addresses on a 1-3/4 inch door. The Sargent 82-5434 spring serves the guard bolt mechanism, so it is the part to order when the bolt itself is sluggish to retract or extend rather than when the trim is loose. Match the part to the brand of lock already in the door.
8) Where does a guard bolt spring like the Sargent 82-5434 typically get used?
Anywhere Sargent commercial locks are in daily service: office buildings, schools, hospitals, retail, government and municipal buildings, warehouses, and multi-tenant residential. High-cycle openings are where guard bolt springs fatigue first, so MRO shops standardized on Sargent often keep a few on the shelf.
9) Can I replace the whole commercial lock instead of ordering the 82-5434 spring?
Replacing the lockset is always an option, but the Sargent 82-5434 exists so that a worn or damaged guard bolt spring can be swapped without pulling the full assembly, restoring lock functionality on installed commercial hardware. It is a genuine OEM Sargent replacement part matched to compatible Sargent mechanical lock assemblies, so the rest of the lock and its keying stay as they are. Trim-level parts such as the Corbin Russwin 499F838 swivel spindle pin with set screw serve a different repair on a different brand of lock.
